| Accounting Policies [Abstract] | |
| Description of Business | Description of Business RxSight ® , Inc. (the “Company”) is a Delaware corporation headquartered in Aliso Viejo, California with one wholly owned subsidiary located in Amsterdam, Netherlands. The wholly owned subsidiary has a registered branch in the United Kingdom and a wholly owned subsidiary located in Germany. The Company is engaged in the research and development, manufacture and sale of light adjustable intraocular lenses used in cataract surgery along with capital equipment used with the lenses. The Company’s products, which include the light adjustable lens (“LAL ® ”) and a specially designed machine for delivering light to the eye, the Light Delivery Device (“LDD ”), are approved by the United States (“U.S.”) Food and Drug Administration (“FDA”) primarily for sale in the U.S. and have regulatory approval in the U.S., Europe, Canada and Mexico. The Company began marketing its products in 2019. The LAL is a premium intraocular lens (“IOL”) which is partially reimbursable under Medicare. The Company competes with other IOLs in the premium market in the U.S. and Europe. |
| Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of RxSight, Inc. and its wholly-owned subsidiaries, RxSight, B.V., located in the Netherlands, and RxSight GmbH, located in Germany. The Company translates the financial statements of its foreign subsidiaries using end-of-period exchange rates for assets and liabilities and average exchange rates during each reporting period for results of operations. All significant inter-company balances and transactions have been eliminated in consolidation. |
| Operating Segments | Operating Segments The Company determined its operating segment on the same basis that it uses to evaluate its performance internally. The Company’s chief operating decision-maker (“CODM”), its Chief Executive Officer, reviews its consolidated operating results for the purpose of allocating resources and evaluating financial performance. The Company determined that it operates and manages its business (including its non-U.S. subsidiaries) in one reportable segment: the research and development, manufacture and sale of light adjustable lenses and related capital equipment. |
| Liquidity | Liquidity |
| Initial Public Offering ('IPO') | Initial Public Offering ( “ IPO ” ) On July 22, 2021, the Company’s Board of Directors (“Board”) approved an amendment to the Company’s certificate of incorporation to effect a reverse split of shares of the Company’s common stock, excluding Series G and Series W common stock, and convertible preferred stock on a 1-for-10.33 basis (“Reverse Stock Split”). The par values of the common stock and convertible preferred stock were not adjusted as a result of the Reverse Stock Split. The Reverse Stock Split was effected on July 23, 2021. Accordingly, all common stock, excluding Series G and Series W common stock, options to purchase common stock, convertible preferred stock, share data, per share data and related information contained in the accompanying consolidated financial statements and notes have been retrospectively adjusted to reflect the effect of the Reverse Stock Split for all periods presented. Outstanding stock options were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased. The Reverse Stock Split resulted in an adjustment to the convertible preferred stock conversion prices to reflect a proportional decrease in the number of shares of common stock to be issued upon conversion. On July 29, 2021 , the Company completed its IPO which resulted in the issuance and sale of 8,248,549 shares of its common stock at a price of $ 16.00 per share. The aggregate net proceeds from the offering, which included 898,549 common shares sold upon the partial exercise of the underwriters’ over-allotment option, after deducting underwriting discounts and commissions of $ 9.2 million and other offering costs of $ 3.2 million, were approximately $ 119.6 million. Immediately prior to the completion of the IPO, (i) 14,376,272 outstanding shares of the Company's convertible preferred stock were converted into an aggregate of 14,725,309 shares of common stock and (ii) 225,945 warrants to purchase Series H convertible preferred stock were exercised and converted into 100,261 shares of common stock. |
| Shelf Registration Statement | Shelf Registration Statement On August 8, 2022, the Company filed a $ 200.0 million shelf registration statement on Form S-3 (“shelf registration statement”) which became effective on August 12, 2022. The shelf registration statement is effective for three years and permits the Company to sell, from time to time, up to $ 200.0 million in aggregate value of common stock, preferred stock, debt securities, warrants, and/or units. The shelf registration statement is intended to provide the Company with flexibility to access additional capital. Included in the $ 200.0 million shelf registration statement the Company also filed a prospectus supplement to sell up to an aggregate value of $ 50.0 million dollars of common stock through an “at-the-market” (“ATM”) offering. During the year ended December 31, 2022 the Company sold 475,875 common shares “at-the-market” for $ 6.0 million in proceeds after deducting underwriting discounts and commissions and other offering expenses. As of December 31, 2022 and 2021 the Company has cash, cash equivalents and short-term investments of $ 105.8 million and $ 159.3 million, respectively. The Company began generating revenue from its principal operations in 2019. The Company has a limited operating history, and the revenue and income potential of the Company’s business and market are unproven. The Company has experienced recurring net losses and negative cash flows from operating activities since its inception. For the years ended December 31, 2022 and 2021, the Company incurred losses from operations of $ 63.3 million and $ 52.8 million, respectively. The Company expects to continue to incur net operating losses into the foreseeable future. Successful transition to attaining profitable operations is dependent upon gaining market acceptance of the Company’s products and achieving a level of revenues adequate to support the Company’s cost structure. The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. The Company believes that existing cash resources will be sufficient to meet projected operating requirements for at least 12 months from the date of issuance of the accompanying consolidated financial statements. The Company plans to continue to fund its losses from operations using its cash, cash equivalents and short-term investments as of December 31, 2022 and meet its future capital funding needs through equity or debt financings, other third-party funding, collaborations, strategic alliances and licensing arrangements or a combination of these. There can be no assurance that the Company will be able to obtain additional financing on acceptable terms, or at all. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible and/or suspend or curtail planned programs. Any of these actions could materially harm the Company’s business, results of operations and future prospects. |
| Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make informed estimates, judgments and assumptions that affect the reported amounts in the consolidated financial The Company’s consolidated financial statements as of and for the year ended December 31, 2022 reflect the Company’s estimates of the impact of the macroeconomic environment, including the impact of inflation, higher interest rates, foreign exchange rate fluctuations and the COVID-19 pandemic. The duration and the scope of these conditions cannot be predicted; therefore, the extent to which these conditions will directly or indirectly impact the Company’s business, results of operations and financial condition, is uncertain. The Company is not aware of any specific event or circumstance that would require an update to its estimates, judgments and assumptions or a revision of the carrying value of the Company’s assets or liabilities as of the date of this filing. |
| Cash and Cash Equivalents | Cash Equivalents Cash equivalents consist of investments in money market accounts. The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase that can be liquidated without prior notice or penalty to be cash equivalents. Cash equivalents are recorded at face value or cost, which approximates fair market value. |
| Short-Term Investments | Short-term Investments Short-term investments are classified based on the maturity date of the related securities. Based on the nature of the assets, the Company’s short-term investments, which are government securities, are classified as available-for-sale and are recorded at their estimated fair value as determined by prices for identical or similar securities at the balance sheet date. The Company’s short-term investments consist of Level 2 financial instruments in the fair value hierarchy. Unrealized gains and losses are recorded as a component of Other Comprehensive Loss within Stockholders’ Equity on the consolidated balance sheets. Realized gains and losses are included as other income (expense) in the accompanying Consolidated Statements of Operations and Comprehensive Loss. The cost basis for realized gains and losses on available-for-sale securities is determined on a specific identification basis. Management determines the appropriate classification of its investments at the time of purchase and reevaluates such determination at each balance sheet date. The Company periodically reviews its investments for unrealized losses other than credit losses and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. In determining whether the carrying value is recoverable, management considers the following factors: • whether the investment has been in a continuous loss position for over 12 months; • the duration to maturity of investments; • intention and ability to hold the investment to maturity and if it is not more likely than not that the Company will be required to sell the investment before recovery of the amortized cost basis; • the credit rating, financial condition and near-term prospects of the issuer and • the type of investments made. The Company recognized $ 75,000 and $ 9,000 of unrealized losses related to short-term investments as of December 31, 2022 and 2021, respectively. At each reporting date, the Company performs an evaluation of impairment to determine if any unrealized losses are the result of credit losses. The Company did no t record an allowance for credit losses for these investments as of December 31, 2022 and December 31, 2021 . For additional information see Note 3 – Short-Term Investments. |
| Restricted Cash | Restricted Cash Restricted cash consists of cash held as collateral for a letter of credit as security for future facility lease payments and corporate credit cards at the Company’s bank. Restricted cash decreased $ 50,000 during the year ended December 31, 2022 to $ 761,000 as required for these operating activities. The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets to the amount reported in the Consolidated Statement of Cash Flows for the years ended December 31, 2022 and 2021 (in thousands).
Year Ended December 31,
2022 2021
Cash and cash equivalents $ 11,834 $ 24,361
Restricted cash 761 811
Cash, cash equivalents and restricted cash in the consolidated statements of cash flows $ 12,595 $ 25,172 |
| Concentration of Credit Risk and Other Risks and Uncertainties | Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments which potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents, short-term investments and accounts receivable. The Company’s policy is to invest cash in institutional money market funds and marketable securities of the U.S. government to limit the amount of credit exposure. The Company currently maintains a portfolio of cash equivalents and short-term investments in money market funds and U.S. treasury bills. Additionally, the Company has established guidelines regarding diversification of its investments and their maturities, which are designed to maintain principal and maximize liquidity. The Company has not experienced material losses on cash equivalents and short-term investments. The Company’s products require approval from the FDA and foreign regulatory agencies before commercial sales can commence. There can be no assurance that the Company’s products will receive any of these required approvals. The denial or delay of such approvals may have a material adverse impact on the Company’s business and may impact business in the future. In addition, after approval by the FDA, there is still an ongoing risk of adverse events that did not appear during the device approval process. The Company is subject to risks common to companies in the medical device industry, including, but not limited to, new technological innovations, clinical development risk, establishment of appropriate commercial partnerships, protection of proprietary technology, compliance with government and environmental regulations, uncertainty of market acceptance of the Company's products, product liability and the need to obtain additional financing. |
| Accounts Receivable | Accounts Receivable Accounts receivable pertain to contracts with customers who are granted credit by the Company in the ordinary course of business and are presented net of allowances for credit losses. Accounts receivable are typically due between 30 and 90 days after invoicing. The Company maintains an allowance for credit losses resulting from the inability of its customers, including ambulatory surgery centers, to make required payments. The allowance for credit losses is calculated quarterly and is developed using an aging of receivables where receivables are segregated into various categories based upon due date, and a historical loss percentage is applied to each category that is adjusted for current receivable composition, counterparty and specific risk and prevailing economic condition and supportable forecasted economic conditions. Once a receivable is deemed uncollectible after collection efforts have been exhausted, it is written off against the allowance for credit losses. The Company closely monitors the credit quality of its customers and has yet to experience a write-off of a receivable or uncollected receivable. The Company does not generally require collateral or other security on receivables. The Company has a diverse customer base and as of December 31, 2022, and 2021 the Company did not have any customer who individually accounted for greater than 10 % of accounts receivable. After evaluation of the collectability of accounts receivable, the Company did no t record any significant allowance for credit losses as of December 31, 2022 or December 31, 2021 . |
| Fair Value of Financial Instruments | Fair Value of Financial Instruments Fair value is measured as the price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques that are consistent with the market, income or cost approach are used to measure fair value. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels: Level 1—Observable inputs such as unadjusted quoted prices in active markets that are accessible at the measurement date for identical unrestricted assets or liabilities. Level 2—Inputs (other than quoted prices included in Level 1) that are either directly or indirectly observable for the asset or liability, for substantially the full term of the asset or liability, through correlation with market data. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and inputs to valuation models or other pricing methodologies that do not require significant judgment because the inputs used in the model, such as interest rates and volatility, can be corroborated by readily observable market data. Level 3—One or more significant inputs that are unobservable and supported by little or no market activity and reflect the use of significant management judgment and assumptions. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques and significant management judgment or estimation. These include the Black-Scholes option-pricing model which uses inputs such as expected volatility, risk-free interest rate and expected term to determine fair market valuation. Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification at each reporting date. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The Company did not have any transfers of assets and liabilities between the levels of the fair value measurement hierarchy during the years presented. Cash, cash equivalents, accounts receivable and accounts payable are carried at their estimated fair value because of the short-term nature of these assets and liabilities. The Company’s short-term investments in government securities are carried at fair value, determined based on publicly available quoted market prices for identical securities at the measurement date. The Company believes the fair values of its operating lease liabilities and term loan at December 31, 2022 and 2021 approximated their carrying values, based on the borrowing rates that were available for loans with similar terms as of that date. |
| Inventories | Inventories Inventories consist of raw materials, work-in-process and finished goods. Raw materials are comprised of chemicals and parts used in the production of the Company's lenses, cartridges, and LDDs. Finished goods are comprised of lenses, cartridges, accessories and LDDs. Inventories are valued at the lower of cost or net realizable value. Cost is computed using standard cost, which approximates actual cost on a first-in, first-out basis. The carrying value of inventories is reviewed for potential impairment whenever indicators suggest that the cost of inventories exceeds the carrying value and management adjusts the inventories to its net realizable value. The cost of finished goods and work-in-process is comprised of raw materials, direct labor, other direct costs and related production overhead to the extent that these costs do not exceed the net realizable value of the goods produced. The Company periodically reviews inventories for potential impairment, estimated losses from obsolescence, material expirations or unmarketable inventories or excess inventories and writes down the cost of inventories to net realizable value at the time such determinations are made. Net realizable value is determined using the estimated selling price, in the ordinary course of business, less estimated costs to complete and dispose. |
| Long-Lived Assets | Long-Lived Assets Property and equipment and leasehold improvements are recorded at cost, net of accumulated depreciation and amortization. Property and equipment are depreciated over the estimated useful lives of the related assets, generally three to five years , using a straight-line method. Leasehold improvements are amortized on the straight-line method over the shorter of the lease term or their estimated economic lives. Repairs and maintenance costs are charged directly to operations as incurred, while renewals and betterments are capitalized. All long-lived assets are reviewed for impairment whenever circumstances such as events or changes in the business indicate that an asset or asset group’s carrying value may not be recoverable based on undiscounted future operating cash flows to be derived from their use. Factors that are considered important that could trigger an impairment review include a current period operating or cash flow loss or a history of operating or cash flow losses and a projection or forecast that demonstrates continuing losses or insufficient income associated with the use of a long-lived asset or asset group. Other factors include a significant change in the manner of the use of the asset or a significant negative industry or economic trend. This evaluation is performed based on estimated undiscounted future cash flows from operating activities compared with the carrying value of the related assets. If the undiscounted future cash flows are less than the carrying value, an impairment loss is recognized, measured by the difference between the carrying value and the estimated fair value of the assets. Fair value is determined primarily using the discounted cash flows expected to be generated from the use of assets. Significant management judgment is required in the forecast of future operating results that are used in the preparation of expected cash flows. |
| Leases | Leases Lease right-of-use assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized when the Company takes possession of the leased property (“Commencement Date”) based on the present value of lease payments over the lease term. The Company estimates the incremental borrowing rate based upon the cost of its own debt financing, current market interest rates and quoted offerings or the rate implicit in the lease. Operating lease right-of-use assets also include any lease payments made at or before lease commencement and exclude any lease incentives received. The lease terms used to calculate the right-of-use asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Rent expense on noncancelable leases containing known future scheduled rent increases is recorded on a straight-line basis over the term of the respective leases beginning on the Commencement Date. The difference between rent expense and rent paid is accounted for as a component of operating lease right-of-use assets on the accompanying consolidated balance sheets. Landlord improvement allowances and other such lease incentives are recorded as property and equipment and as reduction of the right-of-use leased assets and are amortized on a straight-line basis as a reduction to operating lease costs. Leases with an initial term of 12 months or less are expensed as incurred and are not recorded as right-of-use assets on the consolidated balance sheets. |
| Net Income (Loss) per Share | Net Loss per Share Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average shares of common stock outstanding for the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average shares of common stock and potentially dilutive securities outstanding for the period determined using the treasury-stock and if-converted methods. Diluted net loss per share is calculated by dividing net loss by the weighted-average number of shares of common stock and potential dilutive securities outstanding during the period. The following outstanding potentially dilutive securities were excluded from the calculation of diluted net loss per share attributable to common stockholders because their impact under the treasury stock method was anti-dilutive for the periods presented:
Year Ended December 31,
2022 2021
Stock options issued and outstanding under the Calhoun Vision, Inc. 2006 Stock Plan, Calhoun Vision, Inc. 2015 Equity Incentive Plan and the 2021 Equity Incentive Plan 1,926,226 2,144,860
Restricted stock units 543,538 223,716
Stock issuable in offering period under the 2021 Employee Stock Purchase Plan 48,594 8,248 |
| Revenue Recognition | Revenue Recognition The Company’s revenue is generated from the sale of LALs used in cataract surgery along with a specifically designed machine for delivering light to the eye, the LDD, to adjust the lens post-surgery, as needed. Revenue is recognized from sales of products in the U.S. and Europe. Customers are primarily comprised of ambulatory surgery centers, hospitals, and physician private practices. The Company recognizes revenues when promised goods or services are transferred to customers at a transaction price that reflects the consideration to which the Company expects to be entitled in exchange for those goods and services. Specifically, the Company applies the following five steps to recognize revenue: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, the Company satisfies a performance obligation. The Company applies the five-step model to contracts when it is probable that it will collect the consideration to which it is entitled in exchange for the goods or services it transfers to the customer. At contract inception, the Company assesses the goods promised within each customer contract to determine the individual deliverables in its product offerings as separate performance obligations and assesses whether each promised good or service is distinct. The transaction price is determined based on the consideration expected to be received, based either on the stated value in contractual arrangements or the estimated cash to be collected in non-contracted arrangements. The Company recognizes revenue as the amount of the transaction price that is allocated to the respective performance obligation when, or as, the performance obligation is satisfied, considering whether or not this occurs at a point in time or over time. The Company elected to account for shipping costs as fulfillment costs rather than a promised service and excludes from revenue any taxes collected from customers that are remitted to government authorities. The Company’s LDD contracts contain multiple performance obligations bundled for one transaction price, with all obligations generally satisfied within one year. For these bundled arrangements, the Company accounts for individual products and services as separate performance obligations if they are distinct, that is, if a product or service is separately identifiable from other items in the bundled package, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company’s LDD contracts include a combination of the following performance obligations: (i) LDD capital asset and related components, (ii) training and (iii) device service (initial year). Each of these three performance obligations are considered distinct. The LDD capital asset is distinct because the customer can benefit from it together with other resources that are readily available to the customer. Training on the use of the machine is offered as a distinct activity after installation of the LDD to enhance the customer’s ability to utilize the machine by having an industry professional provide best practices and customize training to the specific needs of the customer. Each LDD comes with a twelve-month manufacturer’s warranty (service-type) that includes preventative maintenance, unscheduled service (labor and parts) and software updates. After the first year, service contracts can be purchased separately on a standalone basis. The Company recognizes revenue as performance obligations are satisfied by transferring control of the product or service to a customer. Specifically, revenue for the LDD capital asset is recognized at a point in time at installation. Revenue for training is also recorded at a point in time, generally 60 days after installation. Revenue for the device service is recognized ratably over time after installation, generally 12 months. The Company has determined that the transaction price is the invoice price, net of adjustments, if any. The allocation to the separate performance obligations is based upon the relative standalone selling price. Standalone selling prices are based on observable prices at which the Company separately sells the products or services. The Company estimates the standalone selling price using the market assessment approach considering market conditions and entity-specific factors including, but not limited to, features and functionality of the products and services, geographies, type of customer and market conditions. The Company regularly reviews and updates standalone selling prices as necessary. LALs are generally held at customer sites on consignment. The single performance obligation is satisfied, and revenue is recognized for LALs upon customer notification that the LALs have been implanted in a patient. For the years ended December 31, 2022 and 2021, credits related to returns and rebates on list prices were not significant. The Company has adopted the practical expedient permitting the direct expensing of costs incurred to obtain contracts where the amortization of such costs would occur over one year or less, and it applied to substantially all the Company’s contracts. Revenue for service agreements is recognized ratably over the term of each contract. For the years ended December 31, 2022 and 2021, contract liabilities from sales activity recorded as liabilities on the Company's consolidated balance sheets consisted of the following (in thousands):
Year Ended December 31,
2022 2021
Balance at beginning of period $ 540 $ 345
Additions during the period 2,052 793
Revenue recognized during the period ( 1,405 ) ( 598 )
Balance at end of period $ 1,187 $ 540 For the year ended December 31, 2022 and 2021 , the Company did not have any customers who individually accounted for greater than 10 % of revenue. |
| Cost of Sales | Cost of Sales Cost of sales consists of materials, labor and manufacturing overhead incurred to produce the Company’s products as well as the cost of shipping and handling. Overhead costs include the cost of quality assurance, material procurement, inventory control, facilities, equipment and operations supervision and management, including stock-based compensation. Cost of sales also includes depreciation expense for production equipment and certain direct costs such as royalty and license fee expenses. |
| Research and Development Expense | Research and Development Expenses Research and development expenses are expensed as incurred. Research and development expenses consist of upfront fees and milestones paid to collaborators and expenses incurred in performing research and development activities for new products and technology. The expenses include personnel-related costs, including compensation and benefits and stock-based compensation, consultants hired to perform research projects, costs incurred at clinical trial sites, regulatory and manufacturing engineering costs related to FDA premarket approval submission preparation, various laboratory and research supplies, write-off of pre-approved inventory utilized for clinical trial and research purposes, costs incurred in the development of manufacturing processes in excess of capitalizable value, fees paid to contract research organizations and direct FDA related costs. The Company also accrued the costs of ongoing clinical trials associated with programs that have been terminated or discontinued for which there is no future economic benefit at the time the decision is made to terminate or discontinue the program. |
| Stock Based Compensation | Stock-Based Compensation The Company recognizes compensation expense for equity-based awards on the date of grant to employees, board of directors and consultants based on the estimated grant date fair value of the award Equity-based payments include stock options, restricted stock units and employee stock plan purchases. The fair value of the option awards are estimated using the Black-Scholes option-pricing model and recognized in expense in the consolidated statements of operations and comprehensive loss over the requisite service period, which is generally four years. The Company amortizes the stock-based compensation for equity awards with service conditions on a straight-line basis over the vesting period of the awards. Compensation cost for stock options with performance conditions is recognized based upon the probability of that performance condition being met. Forfeitures of unvested stock option awards are recognized as reductions of expense as they occur. The Black-Scholes option-pricing model requires the use of assumptions about a number of variables, such as the fair market value of the Company’s common stock, the risk-free interest rate, dividend yield, expected term and expected volatility: • Prior to the Company's shares being traded on the Nasdaq Global Market, the fair value of the Company’s common stock was determined by the Company’s Board at the time of each option grant by considering a number of objective and subjective factors. These factors included the valuation of a select group of public peer group companies within the medical device industry that focus on technological advances and development that the Board believed were comparable to the Company’s operations. Operating and financial performance, the lack of liquidity of the common stock and trends in the broader economy and medical device industry also impacted the determination of the fair value of the common stock. In addition, the Company regularly engaged a third-party valuation specialist to assist with estimates related to the valuation of the Company’s common stock. For all grants subsequent to the Company's shares being traded on the Nasdaq Global Market in July 2021, the fair value of common stock was determined by using the closing price per share of common stock as reported on the Nasdaq Global Market; • The risk-free interest rate used is based on the published U.S. Department of Treasury interest rates in effect at the time of stock option grant for zero coupon U.S. Treasury notes with maturities approximating each grant’s expected term; • The dividend yield is zero as the Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future; • Due to the lack of historical exercise history, the expected term for options granted is calculated using the “simplified method” and represents the average time that options are expected to be outstanding based on the mid-point between the vesting date and the end of the contractual term of the award; • Expected volatility is derived from the historical volatilities of a select group of comparable peer companies, for a look-back period commensurate with the expected term of the stock options, as the Company has limited trading history of common stock. |
| Income Taxes | Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The likelihood of realizing the tax benefits related to a potential deferred tax asset is evaluated, and a valuation allowance is recognized to reduce that deferred tax asset if it is more likely than not that all or some portion of the deferred tax asset will not be realized. Deferred tax assets and liabilities are calculated at the beginning and end of the year; the change in the sum of the deferred tax asset, valuation allowance and deferred tax liability during the year generally is recognized as a deferred tax expense or benefit. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the Consolidated Statements of Operations and Comprehensive Loss in the period that includes the enactment date. Significant judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities and the valuation allowance recorded against net deferred tax assets. The Company assesses the likelihood that deferred tax assets will be recovered as deductions from future taxable income. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis and includes a review of all available positive and negative evidence. Factors reviewed include projections of pre-tax book income for the foreseeable future, determination of cumulative pre-tax book income after permanent differences, earnings history and reliability of forecasting. The Company recognized a valuation allowance on deferred tax assets as of December 31, 2022 and 2021 after evaluating that it is more likely than not that deferred tax assets will not be realized as of those dates. The Company evaluates the accounting for uncertainty in income tax recognized in the consolidated financial statements and determines whether it is more likely than not that a tax position will be sustained upon examination by the appropriate taxing authorities before any part of the benefit is recorded in its consolidated financial statements. For those tax positions where it is “not more likely than not” that a tax benefit will be sustained, no tax benefit is recognized. Where applicable, associated interest and penalties are also recorded. The Company has no t accrued any liabilities for any such uncertain tax positions as of December 31, 2022 or 2021. The Company is subject to U.S. federal and state tax authority examinations for all the years since inception due to net operating loss and tax credit carryforwards. The net operating losses and tax credits are subject to adjustment until the statute closes on the year the attributes are ultimately utilized. The Company’s income tax returns are based on calculations and assumptions that are subject to examination by the Internal Revenue Service and other tax authorities. In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. While the Company believes it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcomes of examinations by tax authorities in determining the adequacy of its provision for income taxes. The Company continually assesses the likelihood and amount of potential revisions and adjusts the income tax provision, income taxes payable and deferred taxes in the period in which the facts that give rise to a revision become known. The Company is required to file federal and state income tax returns in the United States, United Kingdom, Germany and Netherlands. The preparation of these income tax returns requires the Company to interpret the applicable tax laws and regulations in effect on such jurisdictions, which could impact the amount of tax paid. An amount is accrued for the estimate of additional tax liabilities, including interest and penalties, for any uncertain tax positions taken or expected to be taken in an income tax return. The accrual for uncertain tax positions is updated when more definitive information becomes available. |
| Comprehensive Loss | Comprehensive Loss All components of comprehensive loss, including net loss, are reported in the consolidated financial statements in the period in which they are recognized. Comprehensive loss is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources, including unrealized gains and losses on marketable securities and foreign currency translation adjustments. |
| Operating Segments | Operating Segments Operating segments are defined as components for which discrete financial information is available for evaluation by the chief operating decision maker to make resource allocation decisions and conduct performance assessments. The Company determined that it operates and manages its business (including its non-U.S. subsidiaries) in one reportable segment: the research and development, manufacture and sale of light adjustable lenses and related capital equipment. |
| Emerging Growth Company Status | Emerging Growth Company Status The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has irrevocably elected to not take this exemption and, as a result, will adopt new or revised accounting standards on the relevant effective dates on which adoption of such standards is required for other public companies that are not emerging growth companies. |
| Recently Adopted Accounting Pronouncements | Recent Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASU”). ASUs not listed below were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s consolidated financial statements. In June 2020, the FASB issued ASU No. 2020-06, “Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, ” ( “ ASU No. 2020-06”) which is intended to simplify the accounting for convertible instruments. This new guidance eliminates certain models that require separate accounting for embedded conversion features and eliminates certain of the conditions for equity classification for contracts in an entity’s own equity. Accordingly, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The new guidance can be adopted through either a modified retrospective method of transition or a fully retrospective method of transition. ASU 2020-06 is effective for public business entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. The Company adopted ASU 2020-06 effective January 1, 2022 using the modified retrospective method and the adoption did not have a material impact on the Company’s consolidated financial statements. |
