| Accounting Policies [Abstract] | |
| Basis of Presentation and Principles of Consolidation | The Company’s condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. The unaudited interim financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results for the periods presented. All such adjustments are of a normal and recurring nature. The December 31, 2022 balance sheet data was derived from audited financial statements; however, the accompanying notes to the condensed consolidated financial statements do not include all of the annual disclosures required under GAAP and should be read in conjunction with the audited consolidated financial statements included in the Company’s 2022 Annual Report on Form 10-K filed with the SEC on March 6, 2023. The operating results presented in these unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for any future periods. 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. |
| Initial Public Offering and Reverse Stock Split | Public Offering On February 7, 2023 , the Company entered into an underwriting agreement with BofA Securities, Inc., in which the Company agreed to issue and sell 4,000,000 shares of the Company's common stock in a public offering (“Public Offering”), pursuant to the shelf registration statement. The shares of common stock were sold at a price to the public of $ 12.50 per share. Under the terms of the underwriting agreement, the Company also granted the underwriters an option exercisable for 30 days from the date of the underwriting agreement to purchase up to an additional 600,000 shares of common stock on the same terms and conditions. The underwriters' option was exercised in full on February 10, 2023 and closed on February 14, 2023. The Company received net proceeds of approximately $ 53.6 million from the Public Offering, after deducting underwriters' discounts and commissions of $ 3.5 million and offering expenses of $ 0.5 million. As of March 31, 2023 and December 31, 2022 the Company had cash, cash equivalents and short-term investments of $ 153.9 million and $ 105.8 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 three months ended March 31, 2023 and 2022, the Company incurred losses from operations of $ 13.1 million and $ 16.6 million, respectively. Based on the Company’s anticipated sales growth in relation to the anticipated costs associated with, among other things, its continuing research and development activities and the expansion of its sales and marketing activities, 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 condensed 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 condensed consolidated financial statements, though the Company expects to continue to incur operating losses and negative cash flows. The Company plans to continue to fund its losses from operations using its cash, cash equivalents and short-term investments as of March 31, 2023 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. If the Company raises additional funds by issuing equity securities, its stockholders may experience dilution. Any future debt financing into which the Company enters may impose additional covenants that restrict operations, including limitations on its ability to incur liens or additional debt, pay dividends, repurchase common stock, make certain investments or engage in certain merger, consolidation or asset sale transactions. Any debt financing or additional equity raise may contain terms that are not favorable to the Company or its stockholders. If the Company is required to enter into collaborations and other arrangements to address its liquidity needs, it may have to give up certain rights that limit its ability to develop and commercialize product candidates or may have other terms that are not favorable to the Company or its stockholders, which could materially and adversely affect its business and financial prospects. 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. |

| 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 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. At the time of filing the 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. ATM Offering As of March 31, 2023 , through the ATM offering, a total of 1,355,216 shares of the Company's common stock, for total net proceeds of $ 16.9 million, have been issued and sold, of which 879,341 shares of the Company's common stock, for net proceeds of $ 10.9 million, were sold during the quarter ended March 31, 2023. Public Offering On February 7, 2023 , the Company entered into an underwriting agreement with BofA Securities, Inc., in which the Company agreed to issue and sell 4,000,000 shares of the Company's common stock in a public offering (“Public Offering”), pursuant to the shelf registration statement. The shares of common stock were sold at a price to the public of $ 12.50 per share. Under the terms of the underwriting agreement, the Company also granted the underwriters an option exercisable for 30 days from the date of the underwriting agreement to purchase up to an additional 600,000 shares of common stock on the same terms and conditions. The underwriters' option was exercised in full on February 10, 2023 and closed on February 14, 2023. The Company received net proceeds of approximately $ 53.6 million from the Public Offering, after deducting underwriters' discounts and commissions of $ 3.5 million and offering expenses of $ 0.5 million. As of March 31, 2023 and December 31, 2022 the Company had cash, cash equivalents and short-term investments of $ 153.9 million and $ 105.8 million, respectively.

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 condensed consolidated financial statements and disclosures in the accompanying notes as of the date of the accompanying condensed consolidated financial statements. On an on-going basis, management evaluates the most critical estimates and assumptions for continued reasonableness. Actual results may differ materially from the estimates used in the preparation of the accompanying condensed consolidated financial statements under different assumptions or conditions. |
| Significant Accounting Policies | Significant Accounting Policies There have been no significant changes to the accounting policies during the three months ended March 31, 2023 , as compared to the significant accounting policies described in Note 2 of the “Notes to Consolidated Financial Statements” in the Company’s audited consolidated financial statements included in its Annual Report on Form 10-K filed with the SEC on March 6, 2023. |
| 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. |
| 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 condensed consolidated balance sheets. Realized gains and losses are included as other income (expense) in the accompanying Condensed 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 had $ 9,000 of unrealized gains and $ 75,000 of unrealized losses related to short-term investments as of March 31, 2023 and December 31, 2022 , respectively. |
| 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. A portion of the Company's operating cash is held in accounts in excess of the Federal Deposit Insurance Corporation (“FDIC”) insurance limits; however, 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. The Company is subject to the risks related to the global pandemic associated with COVID-19, including local, state, federal and other world-wide mandates imposed to reduce the spread of the virus which could interrupt or reduce the number of cataract surgeries, limit access to ambulatory surgery centers, doctors’ offices and manufacturing facilities, and the expansion of global lead times, particularly in Europe and Asia, leading to a supply interruption from the Company's suppliers. In addition, the Company is currently experiencing inflation and longer lead times and limited availability in its supply chain for certain components and has continued exposure to price and supply risk related to anticipated purchases of certain commodities, materials and products used in its business. |
| Accounts Receivable | Accounts Receivable The Company has a diverse customer base and as of March 31, 2023 and December 31, 2022 the Company did not have any customers who individually accounted for greater than 10 % of accounts receivable. The Company maintains an allowance for credit losses resulting from the inability of its customers, including ambulatory surgery centers, to make required payments. After evaluation of the collectability of accounts receivable, the Company did no t record any significant allowance for credit losses as of March 31, 2023 or December 31, 2022 . |
| Fair Value of Financial Instruments | Fair Value of Financial Instruments The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. 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. The Company’s financial instruments consist principally of cash, cash equivalents, short-term investments, accounts receivable, accounts payable, operating lease liabilities and a term loan. 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 amended term loan at March 31, 2023 and December 31, 2022 approximated their carrying values, based on the borrowing rates that were available for loans with similar terms as of such 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. |
| 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 condensed 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 condensed consolidated balance sheets. |
| Net 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:
Three Months Ended March 31,
2023 2022
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 1,814,375 1,986,088
Restricted stock units issued under the 2021 Equity Incentive Plan 478,610 53,545
Stock issuable in offering period under the 2021 Employee Stock Purchase Plan 51,180 46,733 |
| 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 from sales is recognized for LALs upon customer notification that the LALs have been implanted in a patient. For the three months ended March 31, 2023 and 2022, 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 three months ended March 31, 2023 and 2022, contract liabilities from sales activity recorded as liabilities on the Company's condensed consolidated balance sheets consisted of the following (in thousands):
Three Months Ended March 31,
2023 2022
LDD (including training) $ 6,475 $ 4,569
LAL 10,395 4,105
Service warranty, service contracts, and accessories 619 268
$ 17,489 $ 8,942 As of March 31, 2023 and December 31, 2022, the Company recognized contract liabilities on its condensed consolidated balance sheets of $ 1,388,000 and $ 1,187,000 respectively, related to the service agreement performance obligation. Revenue for service agreements is recognized ratably over the term of each contract. The following table represents the contract liabilities from sales activity for the three months ended March 31, 2023 and 2022, respectively (in thousands):
Three Months Ended March 31,
2023 2022
Balance at beginning of period $ 1,191 $ 540
Additions during the period 795 326
Revenue recognized during the period ( 598 ) ( 244 )
Balance at end of period $ 1,388 $ 622 For the three months ended March 31, 2023 and 2022 , the Company did not have any customers who individually accounted for greater than 10 % of revenue. |
| Stock-Based Compensation Expense | Stock-Based Compensation Expense The Company has three equity incentive compensation plans, the Calhoun Vision, Inc. 2006 Stock Plan (“2006 Plan”), the Calhoun Vision, Inc. 2015 Equity Incentive Plan (“2015 Plan”), and the 2021 Equity Incentive Plan (“2021 Plan”), which are collectively referred to as the (“Equity Plans”). The Company also has an employee stock purchase plan, the 2021 Employee Stock Purchase Plan (“2021 ESPP”). The purpose of the 2021 Plan and 2021 ESPP is to provide a means by which eligible participants may be given an opportunity to benefit from increases in the value of the common stock in order to retain or procure the services of the employees, members of the board of directors of the Company (the “Board”) and consultants and provide them with an incentive to promote the Company’s success and accomplish corporate goals. Stock option awards are granted with an exercise price of no less than 100% of estimated fair market value on the date of grant. Time based awards generally vest over four years as follows, subject to the optionee’s continuing service, (i) one fourth of the total number of shares vest and become exercisable on the one-year anniversary; 1/48th of the total number of shares subject to the option vest and become exercisable on each monthly anniversary thereafter for the remaining three years, or (ii) 1/48th of the total number of shares subject to the option vest and become exercisable each month over four years. 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 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. In determining the fair value of the stock options granted, the Company uses the Black-Scholes option-pricing model. 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, expected term, expected volatility, the risk-free interest rate, and dividend yield as discussed below. Each of these inputs is subjective and generally requires significant judgment. Expected term —The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding. The Company used the simplified method (based on the mid-point between the vesting date and the end of the contractual term) to determine the expected term. Expected volatility —Prior to the completion of the Company ’ s initial public offering (“IPO”), when the Company was privately held and did not have any trading history for its common stock, the expected volatility was estimated based on the average historical volatilities for comparable publicly traded medical device companies over a period equal to the expected term of the stock option grants. Comparable companies were chosen based on their similar size, stage in the life cycle and area of specialty. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of its own stock price becomes available.
