Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview and Basis of Presentation	Note 1. Overview and B asis of Presentation Overview and Organization LENSAR, Inc. (“LENSAR” or the “Company”) is a global medical device business focused on the design, development and commercialization of advanced technology for the treatment of cataracts and management of astigmatism to achieve improved visual outcomes for patients. The Company is a public company whose stock is listed and trading under the symbol “LNSR” on The Nasdaq Stock Market LLC (“Nasdaq”). The Company’s revenue is derived from the sale and lease of the Company’s laser systems, which may include equipment, a consumable referred to as the Patient Interface Device (“PID”), procedure licenses, training, installation, limited warranty and maintenance agreements through extended warranty. The Company has developed its next-generation ALLY ® Adaptive Cataract Treatment System (“ALLY System”), which combines all of the features from the LENSAR Laser System with a dual-pulse laser, integrated in a small, compact cataract treatment system. The ALLY System, which has received clearance from the U.S. Food and Drug Administration (“FDA”), enables cataract surgeons to complete the femtosecond-laser-assisted cataract surgery (“FLACS”) procedure in a single, sterile environment. The Company executed a controlled and targeted initial launch of the ALLY System beginning in August 2022. The ALLY System is available to U.S. cataract surgeons and has also received regulatory clearance in India and the Philippines. In addition, the Company submitted the ALLY System for certification in the European Union, or EU, in September 2022 and, in 2023, submitted documentation to distributors in South Korea, Taiwan, and China for additional marketing or certification applications. The Company has incurred recurring losses and operating cash outflows since its inception and, as of March 31, 2024, had an accumulated deficit of $ 114,048 . The Company expects to continue to incur losses and cash outflows from operating activities for the near-term future. Pricing increases in component parts for the ALLY System resulting from inflationary pressures and related macroeconomic conditions may necessitate an increase in overall cost to customers, which in turn may have an adverse impact on customer demand. Management believes the Company’s cash and cash equivalents on hand, together with cash generated from the future sale and lease of products, will provide sufficient funds for its operating, investing, and financing cash flows for a period of at least twelve months from the date of issuance of these financial statements. The Company expects annual revenue and selling, general and administrative expenses to increase from current levels associated with the increase in ALLY System placements. In addition, the Company's growth depends in part on the Company’s ability to produce the ALLY System in sufficient quantities, within requested timelines and at an acceptable price to satisfy customer demand. The Company’s liquidity needs will be largely determined by the Company’s ability to successfully commercialize its products and the progression, additional regulatory clearances or certifications and launch of the ALLY System in additional jurisdictions in the future. In the future, the Company may need to raise additional capital through equity or debt financings, borrowings under credit facilities or from other sources in the future. The Company may issue securities, including common stock, preferred stock, warrants, and/or debt securities through private placement transactions or registered public offerings in the future. The Company’s ability to raise additional funds will depend, among other factors, on financial, economic and market conditions, many of which are outside of the Company’s control, and the Company may be unable to raise financing when needed, or on terms favorable to the Company. If the necessary funds are not available from these sources, the Company may have to delay, reduce or suspend the scope of its sales and marketing efforts, research and development activities, or other components of its operations. Basis of Presentation These condensed financial statements are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial information and, therefore, omit or condense certain footnotes and other information normally included. The condensed financial statements include all adjustments (consisting only of normal recurring adjustments) that management of the Company believes are necessary for a fair statement of the periods presented. These interim financial results are not necessarily indicative of results expected for the full fiscal year. The December 31, 2023 condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. The accompanying unaudited condensed financial statements and related financial information should be read in conjunction with the Company’s annual audited financial statements and the related notes thereto for the fiscal year ended December 31, 2023 , included in the Annual Report on Form 10-K (the “Annual Report”) as filed with the SEC.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Other than policies noted below, there have been no significant changes to the significant accounting policies disclosed in Note 2, Summary of Significant Accounting Policies , of the annual audited financial statements included in the Annual Report. Accounting Estimates The preparation of condensed financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed financial statements and accompanying notes to the condensed financial statements. The accounting estimates that require management’s most significant, difficult and subjective judgments include, but are not limited to, revenue recognition and allowance for expected credit losses, the valuation of notes receivable and inventory, the assessment of recoverability of intangible assets and their estimated useful lives, the valuation and recognition of stock-based compensation, operating lease right-of-use assets and liabilities, the recognition and measurement of current and deferred income tax assets and liabilities, and the valuation of warrant liabilities. Management evaluates its estimates on an ongoing basis as there are changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from these estimates. As of the date of issuance of these unaudited condensed interim financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update estimates, judgments or revise the carrying value of any assets or liabilities. Derivative Financial Instruments The Company evaluates financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, Derivatives and Hedging (“ASC 815”). For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the condensed statements of operations. Warrants issued by the Company that do not meet the criteria for equity treatment are recorded as liabilities. We do not use financial instruments or derivatives for any trading purposes. Fair Value Measurement The fair value of the Company’s financial instruments are estimates of the amounts that would be received if the Company were to sell an asset or the Company paid to transfer a liability in an orderly transaction between market participants at the measurement date or exit price. The assets and liabilities are categorized and disclosed in one of the following three categories: • Level 1—based on quoted market prices in active markets for identical assets and liabilities. • Level 2—based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3—based on unobservable inputs using management’s best estimate and assumptions when inputs are unavailable. Fair value measurements are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. Related Parties The Company follows ASC 850, Related Party Disclosures , for the identification of related parties and disclosure of related party transactions. In May 2023, the Company completed the Private Placement (as defined in Note 11, Redeemable Convertible Preferred Stock ) with NR-GRI Partners, LP (“NR-GRI”), an affiliate of North Run Capital, LP (“North Run”). Pursuant to the terms of the Private Placement, Thomas B. Ellis and Todd B. Hammer, co-managing partners of North Run, joined the Company’s Board of Directors following the Company’s 2023 Annual Meeting of Stockholders. Refer to Note 9, Warrant Liabilities , and Note 11, Redeemable Convertible Preferred Stock , for more details related to the Private Placement. In June 2023, the Company entered into an international distribution agreement in India with a company owned by an employee at that time. As of April 1, 2024, the owner is no longer an employee of the Company. The Company established the distributor relationship to gain regulatory and operational efficiencies, as well as to establish consistent operations with all other international markets where it conducts business. During the year ended December 31, 2023, the Company began transitioning transactions with customers in India to the distributor. The Company recognized $ 290 in product revenue, $ 301 in cost of product sales, and $ 119 in selling, general and administrative expenses for the three months ended March 31, 2024 associated with its Indian operations. There were no amounts due from, or due to, the distributor at March 31, 2024. Income Taxes Income tax expense/(benefit) from continuing operations for the three months ended March 31, 2024 and 2023 was $ 0 in each period, which resulted primarily from maintaining a full valuation allowance against the Company’s net deferred tax assets. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), certain substantial changes in the Company’s ownership may result in a limitation on the amount of net operating loss and tax credit carryforwards that may be used in future years. During the second quarter of 2023, the Company experienced a change in control event resulting from the Private Placement of Series A Redeemable Convertible Preferred Stock, triggering the application of Section 382 of the Code. Refer to Note 11, Redeemable Convertible Preferred Stock, for more details related to the Private Placement. The Company has not completed an analysis to determine whether any additional limitations have been triggered under Sections 382 and 383 of the Code as of March 31, 2024. The Company computed and applied limitations of tax deductions in the income tax provision computation for the year ended December 31, 2023; however, these limitations do not have a material impact on the financial statements. Due to the existence of the valuation allowance, future changes in the Company’s deferred taxes will not impact its effective tax rate or balance sheet. Recently Issued Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires enhanced disclosures about segment expenses on an annual and interim basis. This standard is effective for the Company’s annual financial statements for the year ending December 31, 2024 and for interim periods beginning in 2025. The Company is currently evaluating the impact of this standard on the financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures, which requires (1) disclosure of specific categories in the rate reconciliation and (2) additional information for reconciling items that meet a quantitative threshold. Additionally, the amendment requires disclosure of certain disaggregated information about income taxes paid, income from continuing operations before income tax expense (benefit) and income tax expense (benefit). The standard is effective for the Company’s annual financial statements for the year ending December 31, 2025. The Company is currently evaluating the impact of this standard on the financial statements.

The Company maintains an allowance for expected credit losses to provide for the estimated amount of receivables that will not be collected. The allowance is based upon an assessment of customer credit worthiness, historical payment experience, the age of outstanding receivables, collateral to the extent applicable and reflects the possible impact of current conditions and reasonable forecasts not already reflected in historical loss information.

Fair Value of Financial Instruments	Note 4. Fair Value of Financial Instruments The carrying value of the Company’s cash, cash equivalents, accounts receivable, accounts payable, accrued liabilities, and other current liabilities approximate fair value based on the short-term maturities of these instruments. The carrying value of the Company’s notes receivable also approximates fair value based on the associated credit risk. The Company classifies money market funds, U.S. treasury bills, certificates of deposit, and U.S. government securities as Level 1 within the fair value hierarchy as the fair value is based on quoted prices. The Company classifies U.S. government agency bonds as Level 2 within the fair value hierarchy as the fair value is based upon quoted market prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active for which all significant inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets. The Company classifies its warrant derivative liabilities as Level 3 within the fair value hierarchy as the Company estimates the fair value of the warrant liabilities using recently quoted market prices of the Company's common stock and the Black-Scholes option pricing model, refer to Note 9, Warrant Liabilities .

Certain intangible assets were established upon PDL BioPharma, Inc.’s acquisition of LENSAR in May 2017. They are being amortized on a straight-line basis over a period of 15 years. The intangible assets for customer relationships are amortized on a straight-line basis or a double declining basis over their estimated useful lives up to 20 years based on the method that better represents the economic benefits to be obtained. 2. LENSAR acquired certain intangible assets for customer relationships from a domestic distributor in an asset acquisition, which are being amortized on a straight-line basis over a period of 10 years. 3. LENSAR acquired certain intangible assets from a medical technology company in an asset acquisition, which are being amortized on a straight-line basis over a period of 15 years. 4.

Warrants and Rights Note Disclosure [Abstract]
Warrant Liabilities	Note 9. Warrant Liabilities In May 2023, the Company completed the Private Placement, which included the issuance of warrants (the “Warrants”) to purchase an aggregate of 4,367 shares of common stock (the “Warrant Shares”). Fifty percent of the Warrants have an exercise price equal to $ 2.45 per share (the “Series A Warrant”), and 50 % of the Warrants have an exercise price equal to $ 3.0625 per share (the “Series B Warrant”), subject in each instance to adjustments as provided under the terms of the Warrants. Refer to Note 11, Redeemable Convertible Preferred Stock , for more details related to the Private Placement. Upon the occurrence of certain transactions (“Fundamental Transactions,” as defined below), the Warrants provide that they are redeemable by the holder thereof for a value determined using a Black Scholes option pricing model with inputs calculated as described in the applicable Warrant, which includes a 100 % floor on the volatility input to be utilized. The Company has determined that this provision introduces leverage to the holders of the Warrants that could result in a value that would be greater than the settlement amount of a fixed-for-fixed option on the Company’s own equity shares. Accordingly, pursuant to ASC 815, the Company classified the fair value of the Warrants as a liability to be re-measured at the end of every reporting period with the change in value reported in the statement of operations. Of the $ 20,000 gross proceeds for the Private Placement, $ 5,605 was allocated to the Warrants and the remaining $ 14,395 was allocated to the Series A Redeemable Convertible Preferred Stock. The Company estimated the fair value of the warrant liabilities using recently quoted market prices of the Company's common stock and the Black-Scholes option pricing model. The fair value of the warrant liabilities was estimated using the following assumptions as of March 31, 2024 and December 31, 2023: March 31, 2024 December 31, 2023 Risk-free interest rate 4.3 % 3.8 % Expected term (years) 4.1 4.4 Expected volatility 55 % 55 % Dividends 0.0 % 0.0 % Expected term : The expected term for the warrant liabilities was based on the remaining contractual term of the Warrants. Risk-free interest rate : The risk-free interest rate was based on the rates paid on securities issued by the U.S. Treasury with a term approximating the expected term. Expected volatility : The expected volatility for the warrant liabilities was based on an index of the historical volatilities of a group of comparable publicly-traded medical device and other peer companies, which the Company believed was representative of the volatility of its common stock. Expected dividend yield : The Company does not intend to pay dividends for the foreseeable future. Accordingly, the Company used a dividend yield of zero in the assumptions.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 10. Commitments and Contingencies Purchase Obligation LENSAR is a party to various supply agreements for the manufacture and supply of certain components. The supply agreements commit LENSAR to a minimum purchase obligation of approximately $ 4,767 over the next nine months. LENSAR expects to meet these requirements. Royalty Payments The Company acquired certain intellectual property that require royalty payments at a rate of 3 % of certain revenue upon the phacoemulsification features being cleared for commercialization and operational in the ALLY System. Employee Retention Credit In March 2020, the United States enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). The CARES Act provides for an employee retention credit (“ERC”), which is a refundable tax credit against certain employment taxes paid in 2020 and 2021. During the quarter ended September 30, 2023 , the Company received a majority of the ERC. As such, the Company recorded $ 1,368 as a reduction of selling, general and administrative expenses, which represents the ERC net of professional fees in the quarter ended September 30, 2023. During the three months ended March 31, 2024 and 2023, no amounts were recorded related to the ERC. Legal Matters The medical device market in which LENSAR participates is largely technology driven. As a result, intellectual property rights, particularly patents and trade secrets, play a significant role in product development and differentiation. From time to time, we may become involved in various legal proceedings relating to matters incidental to the ordinary course of our business, including intellectual property, commercial, product liability, employment, class action, whistleblower and other litigation and claims, and governmental and other regulatory investigations and proceedings. We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. On August 14, 2023, stockholders Ryan Schaper and Christopher P. Bolster filed a Verified Amended Class Action Complaint against the Company and certain of its officers and members of the board of directors (“Defendants”) in the matter captioned Schaper v. LENSAR, Inc., et al., Case No. 1:23-cv-00692-GBW (D. Del.). On August 18, 2023, the parties filed a joint stipulation extending Defendants’ time to respond to the complaint until a lead plaintiff is appointed and plaintiffs file a second amended complaint or designate the Verified Amended Class Action Complaint as operative. On December 12, 2023, the Court appointed Ryan Schaper and Christopher P. Bolster as Lead Plaintiffs. On December 22, 2023, the parties filed a joint stipulation providing that Lead Plaintiffs' will file a second amended complaint or designate the Verified Amended Class Action Complaint as operative on or before January 12, 2024. On January 12, 2024, Lead Plaintiffs filed a Verified Second Amended Class Action Complaint. Defendants filed a motion to dismiss on February 26, 2024. The parties will complete briefing on the motion to dismiss in May 2024. The Company vigorously denies that the definitive proxy statement filed with the SEC on June 20, 2023 was deficient in any respect, or that that supplemental disclosures were required or necessary under applicable laws. At this time, the Company cannot predict the outcome, or provide a reasonable estimate or range of estimates of the possible outcome or loss, if any, in this matter. This matter or other such matters may be time-consuming, divert management’s attention and resources, cause us to incur significant expenses or liability or require us to change our business practices, even if we believe the claims asserted against us are without merit. Because of the potential risks, expenses and uncertainties of litigation, we may, from time to time, settle disputes, even where we believe that we have meritorious claims or defenses. Because litigation is inherently unpredictable, we cannot assure you that the results of any such actions will not have a material adverse effect on our business, results of operations, financial condition or cash flows.

Disclosure Convertible Preferred Stock [Abstract]
Redeemable Convertible Preferred Stock	Note 11. Redeemable Convertible Preferred Stock Series A Redeemable Convertible Preferred Stock In May 2023, the Company entered into a Securities Purchase Agreement (the “SPA”) with NR-GRI Partners, LP (“NR-GRI”), whereby it sold to NR-GRI, for an aggregate purchase price of $ 20,000 , 20 shares of Series A Redeemable Convertible Preferred Stock and the Warrants (the “Private Placement”). Refer to Note 9, Warrant Liabilities , for more details related to the Warrants. The Series A Redeemable Convertible Preferred Stock is convertible into 7,940 shares of common stock at the election of NR-GRI. On August 1, 2023, the Company’s stockholders voted to approve the issuance of shares of the Company’s common stock issuable upon conversion of the shares of Series A Redeemable Convertible Preferred Stock and exercise of the Warrants. As a result of the stockholders’ approval of the Private Placement, applicable ownership limitations under Nasdaq rules were lifted, and NR-GRI became entitled to convert shares of Series A Redeemable Convertible Preferred Stock or exercise Warrants up to the full amount purchased in the Private Placement. Holders of Series A Redeemable Convertible Preferred Stock are entitled to vote on an as-converted basis with holders of common stock. The Series A Redeemable Convertible Preferred Stock ranks senior to the common stock as to distributions and payments upon the liquidation, dissolution and winding up of the Company, and holders of Series A Redeemable Convertible Preferred Stock participate with the holders of the common stock on an as-converted basis to the extent any dividends are declared on common stock. The shares of Series A Redeemable Convertible Preferred Stock will automatically be redeemed in connection with certain transactions (“Fundamental Transactions”), including a merger, sale of all or substantially all the assets of the Company, recapitalization, or the sale by the Company of shares resulting in more than 50 % ownership by a person or group. In such event, the redemption price would be equal to the greater of the stated value of the shares of Series A Redeemable Convertible Preferred Stock or the consideration per share of common stock in the Fundamental Transaction (or in the absence of such consideration, the volume-weighted average price of the Company’s common stock immediately preceding the closing of the Fundamental Transaction). The Series A Redeemable Convertible Preferred Stock is classified as temporary equity in the condensed balance sheet because redemption automatically occurs upon a Fundamental Transaction. However, redemption is not considered probable; therefore, the Series A Redeemable Convertible Preferred Stock is not accreted to face value. The proceeds of the transaction were allocated first to the fair value of warrants due to the classification of the warrants as a liability on the condensed balance sheet and the remainder of the proceeds were allocated to the Series A Redeemable Convertible Preferred Stock. Offering costs of $ 901 were allocated ratably based on the allocation of proceeds; $ 253 was allocated to the general and administrative expenses and $ 648 was allocated to Series A Redeemable Convertible Preferred Stock. Series A Redeemable Convertible Preferred Stock is presented net of offering costs on the condensed balance sheet. In connection with the parties’ entry into the SPA, the Company and NR-GRI entered into a Registration Rights Agreement, pursuant to which the Company filed a resale registration statement on Form S-3 (No. 333-272930) with respect to the resale of the shares of the Company’s common stock issuable upon conversion of the shares of Series A Redeemable Convertible Preferred Stock and exercise of the Warrants.

Stock-Based Compensation	Note 13. Stock-Based Compensation Stock-Based Incentive Plans The 2020 Plan In July 2020, the Board of Directors approved the LENSAR Inc. 2020 Incentive Award Plan (the “2020 Plan”). The 2020 Plan provides for the grant of stock options, restricted stock, restricted stock unit awards and other stock-based awards to recipients. The amount and terms of grants are determined by the Company’s Board of Directors or a duly authorized committee thereof. Participants must pay the Company, or make provisions to pay, any required withholding taxes by the date of the event creating the tax liability. Participants may satisfy the tax liability in cash or in stock. A total of 3,333 shares of common stock were initially reserved for issuance pursuant to the 2020 Plan. The number of shares available for issuance under the 2020 Plan includes an annual increase on the first day of each fiscal year beginning fiscal 2021, equal to the lesser of (i) 5 % of the aggregate number of shares outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number of shares as determined by the Board of Directors. As of March 31, 2024 , the Company has reserved a total of 5,550 shares of common stock for issuance under the 2020 Plan. The Inducement Plan In February 2024, the Board adopted the 2024 Employment Inducement Incentive Award Plan (the “Inducement Plan”). The Inducement Plan provides for the grant of non-qualified stock options, stock appreciation rights, restricted stock awards, restricted stock units, and other stock or cash based awards (collectively, the “Inducement Awards”). The Inducement Plan was recommended for approval by the Compensation Committee of the Board and subsequently approved and adopted by the Board without stockholder approval pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules. A maximum of 100 shares of common stock were reserved for issuance pursuant to the Inducement Plan. In accordance with Rule 5635(c)(4) of the Nasdaq Listing Rules, Inducement Awards under the 2024 Plan may only be made to an employee who has not previously been an employee or member of the Board, or following a bona fide period of non-employment by the Company, if he or she is granted such Inducement Awards in connection with his or her commencement of employment with the Company and such grant is an inducement material to his or her entering into employment with the Company. A summary of the shares available for issuance under the 2020 Plan and Inducement Plan (collectively, the “Incentive Plans”) is as follows: 2020 Plan Inducement Plan Balance at December 31, 2023 294 — Authorized 566 100 Granted/Awarded ( 31 ) ( 4 ) Cancelled/Forfeited 140 — Balance at March 31, 2024 969 96 Stock Options The exercise price of incentive stock options (“ISOs”) and nonqualified stock options (“NSOs”) shall not be less than 100 % of the fair market value on the grant date of the option and the term may not exceed 10 years. The exercise price of ISOs granted to a 10 % stockholder shall not be less than 110 % of the estimated fair market value on the grant date of the option and the term may not exceed five years . To date, options have a term of 10 years and generally vest over one to four years from the grant date. Option award activity under the Incentive Plans is set forth below: Options Outstanding Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (In Years) Aggregate Intrinsic Value Outstanding at December 31, 2023 1,974 $ 5.31 8.0 $ 429 Options granted 34 $ 4.12 Options exercised ( 2 ) $ 2.65 Options cancelled/forfeited ( 108 ) $ 6.45 Outstanding at March 31, 2024 1,898 $ 5.23 8.1 $ 332 Vested and expected to vest at March 31, 2024 1,898 $ 5.23 8.1 $ 332 Vested and exercisable at March 31, 2024 1,088 $ 5.94 7.7 $ 107 The weighted average grant date fair value of options granted during the three months ended March 31, 2024 was $ 2.38 . The total fair value of options vested during the three months ended March 31, 2024 was approximately $ 540 . Total unrecognized compensation expense of $ 2,006 related to stock options will be recognized over a weighted average period of 2.0 years. The following table summarizes information about stock options outstanding and vested as of March 31, 2024: Options Outstanding Options Vested Exercise Price Options Outstanding Weighted Average Remaining Contractual Term (in Years) Weighted Average Exercise Price Number Exercisable Weighted Average Exercise Price $ 2.15 - $ 3.10 355 8.8 $ 2.66 102 $ 2.66 $ 3.23 422 9.2 $ 3.23 193 $ 3.23 $ 3.27 - $ 5.95 54 8.3 $ 4.63 12 $ 5.78 $ 6.04 413 7.7 $ 6.04 225 $ 6.04 $ 6.07 - $ 8.62 654 7.1 $ 7.44 556 $ 7.45 1,898 8.1 $ 5.23 1,088 $ 5.94 The Company estimated the fair value of stock-options using the Black-Scholes option pricing model. The fair value of stock options is being amortized on a straight-line basis over the requisite service period of the awards. The fair value of stock options was estimated using the following assumptions for the three months ended March 31, 2024 and 2023: Three Months Ended 2024 2023 Risk-free interest rate 3.9 - 4.2 % 3.5 - 4.2 % Expected term (years) 6 6 Expected volatility 58 % 70 % Dividends 0.0 % 0.0 % Expected term : The expected term for the Company’s stock-based compensation awards was based on an index of the expected terms of a group of comparable publicly-traded medical device and other peer companies, which the Company believed was representative of the expected term of its awards. Risk-free interest rate : The risk-free interest rate was based on the rates paid on securities issued by the U.S. Treasury with a term approximating the expected term. Expected volatility : The expected volatility for the Company’s stock-based compensation awards was based on an index of the historical volatilities of a group of comparable publicly-traded medical device and other peer companies, which the Company believed was representative of the volatility of its common stock. Expected dividend yield : The Company does not intend to pay dividends for the foreseeable future. Accordingly, the Company used a dividend yield of zero in the assumptions. Restricted Stock Units Restricted stock units granted to employees and non-employees generally vest over one to four years in annual equal increments. The fair value of restricted stock units is based on the Company’s closing stock price on the date of grant. Restricted stock unit activity under the Incentive Plans is set forth below: Restricted Stock Units Outstanding Number of Units Weighted Average Grant Date Fair Value Per Share Non-vested at December 31, 2023 483 $ 3.04 Restricted stock units granted 2 $ 3.55 Restricted stock units vested ( 84 ) $ 3.26 Restricted stock units cancelled ( 14 ) $ 2.65 Non-vested at March 31, 2024 387 $ 3.01 The total fair value of restricted stock units vested during the three months ended March 31, 2024 was approximately $ 274 . At March 31, 2024 there was approximately $ 656 of total unrecognized compensation expense related to restricted stock units, which is expected to be recognized over a weighted-average period of 0.9 years. 2020 Employee Stock Purchase Plan In September 2020, the Board of Directors approved the LENSAR, Inc. 2020 Employee Stock Purchase Plan (the “2020 ESPP”), under which eligible employees are permitted to purchase common stock at a discount through payroll deductions. A total of 340 shares of common stock were initially reserved for issuance. The number of shares available for issuance under the 2020 ESPP includes an increase on the first day of each fiscal year, beginning in 2022, by an amount equal to the lesser of (i) 1.0 % of the outstanding shares of common stock as of the last day of the immediately preceding fiscal year; or (ii) a lesser amount as determined by the Board of Directors. As of March 31, 2024 , the Company has reserved 564 shares of common stock for issuance under the 2020 ESPP. The price of the common stock purchased will be the lower of 85 % of the fair market value of the common stock at the beginning of an offering period or at the end of a purchase period. The 2020 ESPP is intended to qualify as an "employee stock purchase plan" within the meaning of Section 423 of the Code. As of March 31, 2024 , 304 shares of common stock have been issued to employees participating in the 2020 ESPP and 260 shares were available for future issuance under the 2020 ESPP. The grant date fair value of the shares to be issued under the Company’s 2020 ESPP was estimated using the Black-Scholes valuation model. The following table sets forth the total stock-based compensation expense recognized under the Incentive Plans and the 2020 ESPP in the Company's condensed statements of operations: Three Months Ended 2024 2023 Revenue – product $ 2 $ — Cost of revenue – product 51 83 Cost of revenue – service 29 46 Selling, general and administrative expenses 484 1,426 Research and development expenses 86 171 Total $ 652 $ 1,726 Total unrecognized stock-based compensation expense is expected to be amortized as follows: Fiscal Year Amount Remainder of 2024 $ 1,414 2025 1,000 2026 222 2027 26 2028 — Total unrecognized stock-based compensation expense $ 2,662 The amounts included in this table are based on restricted stock units and stock options outstanding at March 31, 2024 and assumes the requisite service period is fulfilled for all awards outstanding. Actual stock-based compensation expense in future periods may vary from those reflected in the table.

Accounting Policies [Abstract]
Accounting Estimates	Accounting Estimates The preparation of condensed financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed financial statements and accompanying notes to the condensed financial statements. The accounting estimates that require management’s most significant, difficult and subjective judgments include, but are not limited to, revenue recognition and allowance for expected credit losses, the valuation of notes receivable and inventory, the assessment of recoverability of intangible assets and their estimated useful lives, the valuation and recognition of stock-based compensation, operating lease right-of-use assets and liabilities, the recognition and measurement of current and deferred income tax assets and liabilities, and the valuation of warrant liabilities. Management evaluates its estimates on an ongoing basis as there are changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from these estimates. As of the date of issuance of these unaudited condensed interim financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update estimates, judgments or revise the carrying value of any assets or liabilities.
Derivative Financial Instruments	Derivative Financial Instruments The Company evaluates financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, Derivatives and Hedging (“ASC 815”). For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the condensed statements of operations. Warrants issued by the Company that do not meet the criteria for equity treatment are recorded as liabilities. We do not use financial instruments or derivatives for any trading purposes.
Fair Value Measurement	Fair Value Measurement The fair value of the Company’s financial instruments are estimates of the amounts that would be received if the Company were to sell an asset or the Company paid to transfer a liability in an orderly transaction between market participants at the measurement date or exit price. The assets and liabilities are categorized and disclosed in one of the following three categories: • Level 1—based on quoted market prices in active markets for identical assets and liabilities. • Level 2—based on observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3—based on unobservable inputs using management’s best estimate and assumptions when inputs are unavailable. Fair value measurements are classified in their entirety based on the lowest level of input that is significant to their fair value measurement.
Related Parties	Related Parties The Company follows ASC 850, Related Party Disclosures , for the identification of related parties and disclosure of related party transactions. In May 2023, the Company completed the Private Placement (as defined in Note 11, Redeemable Convertible Preferred Stock ) with NR-GRI Partners, LP (“NR-GRI”), an affiliate of North Run Capital, LP (“North Run”). Pursuant to the terms of the Private Placement, Thomas B. Ellis and Todd B. Hammer, co-managing partners of North Run, joined the Company’s Board of Directors following the Company’s 2023 Annual Meeting of Stockholders. Refer to Note 9, Warrant Liabilities , and Note 11, Redeemable Convertible Preferred Stock , for more details related to the Private Placement. In June 2023, the Company entered into an international distribution agreement in India with a company owned by an employee at that time. As of April 1, 2024, the owner is no longer an employee of the Company. The Company established the distributor relationship to gain regulatory and operational efficiencies, as well as to establish consistent operations with all other international markets where it conducts business. During the year ended December 31, 2023, the Company began transitioning transactions with customers in India to the distributor. The Company recognized $ 290 in product revenue, $ 301 in cost of product sales, and $ 119 in selling, general and administrative expenses for the three months ended March 31, 2024 associated with its Indian operations. There were no amounts due from, or due to, the distributor at March 31, 2024.
Income Taxes	Income Taxes Income tax expense/(benefit) from continuing operations for the three months ended March 31, 2024 and 2023 was $ 0 in each period, which resulted primarily from maintaining a full valuation allowance against the Company’s net deferred tax assets. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), certain substantial changes in the Company’s ownership may result in a limitation on the amount of net operating loss and tax credit carryforwards that may be used in future years. During the second quarter of 2023, the Company experienced a change in control event resulting from the Private Placement of Series A Redeemable Convertible Preferred Stock, triggering the application of Section 382 of the Code. Refer to Note 11, Redeemable Convertible Preferred Stock, for more details related to the Private Placement. The Company has not completed an analysis to determine whether any additional limitations have been triggered under Sections 382 and 383 of the Code as of March 31, 2024. The Company computed and applied limitations of tax deductions in the income tax provision computation for the year ended December 31, 2023; however, these limitations do not have a material impact on the financial statements. Due to the existence of the valuation allowance, future changes in the Company’s deferred taxes will not impact its effective tax rate or balance sheet.
Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires enhanced disclosures about segment expenses on an annual and interim basis. This standard is effective for the Company’s annual financial statements for the year ending December 31, 2024 and for interim periods beginning in 2025. The Company is currently evaluating the impact of this standard on the financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures, which requires (1) disclosure of specific categories in the rate reconciliation and (2) additional information for reconciling items that meet a quantitative threshold. Additionally, the amendment requires disclosure of certain disaggregated information about income taxes paid, income from continuing operations before income tax expense (benefit) and income tax expense (benefit). The standard is effective for the Company’s annual financial statements for the year ending December 31, 2025. The Company is currently evaluating the impact of this standard on the financial statements.
