Basis of Presentation

Accounting Policies [Abstract]
Basis of Presentation	(1) Basis of Presentation Principles of Consolidation. The accompanying consolidated financial statements have been derived from the historical cost basis of the assets and liabilities, financial condition and cash flows of Presbia PLC and Presbia Ireland, Limited, both organized in Ireland, Presbia Investments, a direct subsidiary of Presbia PLC organized in the Cayman Islands, and Presbia Ireland, Limited’s subsidiaries, Presbia USA, Inc., and OPL, LLC. Presbia USA, Inc. and OPL, LLC are both entities organized in the United States, and include Presbia USA, Inc.’s subsidiaries, Visitome, Inc. and PresbiBio, LLC, both organized in the United States, and OPL, LLC’s direct and indirect subsidiaries, PIP Holdings, C.V and Presbia Cooperatief U.A., both organized in the Netherlands, and PresbiOptical LLC, organized in the United States (collectively, including Presbia PLC, the “Company”). The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company’s fiscal year ends on December 31. The entities presented in the consolidated financial statements have been under common control during the periods presented. All intercompany accounts have been eliminated in consolidation. Basis of Presentation. The accompanying unaudited consolidated financial statements as of June 30, 2016 and for the three and six months ended June 30, 2016 and 2015, respectively, have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting, and with the instructions to Form 10-Q and Article 8 of Regulation S-X, which do not conform in all respects to the requirements of U.S. GAAP for annual financial statements. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements presented in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2015. The accompanying condensed balance sheet as for December 31, 2015 has been derived from the audited financial statements at that date but does not include all the information and footnotes required by GAAP for complete financial statements. The results of operations for the three and six months ended June 30, 2016 are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2016, or any other period. In the opinion of management, the accompanying consolidated financial statements reflect all adjustments which are necessary for a fair presentation of the results of operations and cash flows for the periods presented. The results of operations for such interim periods are not necessarily indicative of results of operations to be expected for the full year. References to amounts in the consolidated financial statement sections are in thousands, except per share data, unless otherwise specified. Reclassification of Prior Year Presentation. Certain prior year amounts have been reclassified for consistency with the current period presentation. These reclassifications had no effect on the reported results of operations and cash flows. Liquidity The Company has incurred significant operating losses since inception and had relied on funding from Presbia Holdings (the “Parent”) to fund operations prior to its IPO on February 3, 2015. Presbia Holdings was dissolved on November 25, 2015 and ceased to be the Parent of Presbia PLC. At June 30, 2016, the Company has an accumulated deficit of $63.2 million. As the Company continues to incur losses, its transition to profitability will depend on the following: (i) the completion of its U.S. staged pivotal trial, obtaining FDA approval of its microlens and, if approval is received from the FDA, the commercialization of its product within the United States and (ii) the successful commercialization of its product in certain jurisdictions outside the United States in which the Company has market approval, including the European Economic Area. The Company may never achieve profitability, and unless and until it does, it will need to continue to raise additional capital. Management expects that existing cash as of June 30, 2016, coupled with anticipated revenues outside of the United States will be sufficient to meet the Company’s anticipated cash requirements, including funding the initial payment for the acquisition of assets from Neoptics, through the second quarter of 2017

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies During the three months and six months ended June 30, 2016 there have been no changes to the Company’s significant accounting policies as described in the Annual Report on Form 10-K for the fiscal year ended December 31, 2015, except for the adoption of new accounting standards as discussed below. Foreign Currency The functional currency of subsidiaries outside the United States of America is the U.S. Dollar. Transactions in foreign currencies during the year are re-measured at rates of exchange on the dates of the transactions. Gains and losses related to re-measurement of items arising through operating activities are accounted for in the statement of operations and comprehensive loss and included in general and administrative expense. Aggregate foreign exchange loss was $7,000 and 16,000 for the three and six month periods ended June 30, 2016, respectively, and aggregate foreign exchange loss was $14,000 and $0 for the three and six month periods ended June 30, 2015, respectively. Comprehensive Loss Comprehensive income or loss is defined as a change in equity of a company attributable to all transactions excluding those transactions resulting from investment with owners and distributions to owners. There were no differences between net loss and comprehensive loss in the three and six month periods ended June 30, 2016 and 2015, respectively. Deferred Offering Costs During the three and six month periods ended June 30, 2015, the Company incurred approximately $0.2 million and $1.2 million, respectively, in costs related to its IPO which was completed on February 3, 2015. Upon completion of the IPO, the Company netted approximately $2.0 million in offering costs against the gross proceeds in shareholders’ deficit. Recent Accounting Standards In March 2016, the Financial Accounting Standards Board issued Accounting Standard Update (ASU) 2016-09 Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 modifies multiple provisions intended to simplify various aspects of accounting for share-based payments including income tax consequences, accounting for forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 will be effective for the Company beginning in the first quarter of 2017. The adoption of this standard is not expected to have a material impact on the Company's financial position or results of operations. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard requires lessees to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets and eliminates certain real estate-specific provisions. ASU 2016-02 will be effective for the Company in the first quarter of 2019. ASU 2016-02 will be adopted on a modified retrospective transition basis for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating the impact of ASU 2016-02 on its consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The new standard requires management to assess, at each annual and interim reporting period, an entity's ability to continue as a going concern within one year after the date that the financial statements are issued and to provide related footnote disclosures. ASU 2014-15 will be effective for the Company beginning in the first quarter of 2017. The Company is currently evaluating the impact of ASU 2014-15 on its consolidated financial statements. In June 2014, the FASB issued ASU 2014-12, Compensation - Stock Compensation (Topic 781): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period. The new standard requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. The Company adopted ASU 201-12 effective as of January 1, 2016, and the adoption of this standard had no impact on the Company's financial position or results of operations. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The new standard is based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will be effective for the Company in the first quarter of 2018 and allows for full retrospective or a modified retrospective adoption approach. The Company has not yet assessed the potential impact of ASU 2014-09 on its consolidated financial statements.

Loss per Share

Loss per Share	6 Months Ended

Earnings Per Share [Abstract]
Loss per Share	(3) Loss per Share Basic net loss per ordinary share is calculated by dividing net loss allocated to ordinary shareholders by the weighted average number of ordinary shares outstanding during the reporting period. Diluted net loss allocated to ordinary shareholders per share is calculated based on the weighted average number of Ordinary Shares and dilutive potential Ordinary Shares outstanding during the period. Dilutive potential ordinary shares consist of the shares issuable upon the exercise of options and upon the vesting of restricted shares under the treasury stock method. In net loss periods, basic and diluted net loss per share are identical since the effect of potential ordinary shares is anti-dilutive and therefore excluded. Basic and diluted loss per share for the three and six months ended June 30, 2016 and 2015 were calculated as follows: Three-Months Ended June 30, Six-Months Ended June 30, 2016 2015 2016 2015 Net Loss $ (3,882 ) $ (5,319 ) $ (7,649 ) $ (9,912 ) Weighted average shares outstanding - basic and diluted 13,337,042 13,333,334 13,337,042 12,539,787 Net loss per ordinary share - basic and diluted $ (0.29 ) $ (0.40 ) $ (0.57 ) $ (0.79 ) Antidilutive securities, which consist of options and restricted shares that are not included in the diluted net loss per share calculation, consisted of an aggregate of approximately 1,111,968 and 1,040,573 for the three months ended June 30, 2016 and 2015, respectively, and 1,112,087 and 844,024 weighted average shares for the six months ended June 30, 2016 and 2015, respectively.

Share Based Awards	(4) Share Based Awards Equity Issued by Parent Liquidation of Presbia Holdings As described in the Company’s Annual Report on form 10-K for the fiscal year ended December 31, 2015, in May 2015 pursuant to a plan to liquidate the Parent and distribute all of its assets to its ordinary shareholder by August 2015, the shareholders of the Parent approved a plan in which all options and unvested restricted shares outstanding as of May 13, 2015 were to become fully vested immediately, and, in the case of the options, the expiration date of the options were accelerated to June 15, 2015. By November 2015, the Company’s Parent was dissolved, and, as such, no share-based compensation expense was recognized in the three and six months ended June 30, 2016. Options Prior to 2014, the Parent granted options to purchase its ordinary shares to both employees and non-employees of the Company and share-based compensation related to such awards was recognized as expense in the Company’s Consolidated Statements of Operation and Comprehensive Loss for all reported periods including the three and six months ended June 30, 2015. Information regarding awards granted in periods prior to 2014 is available in the Company's Annual Reports on Form 10-K for the fiscal years ended December 31, 2015 and 2014. Restricted Shares No restricted shares were granted by the Parent during the three and six months ended June 30, 2015, and, similarly, as of June 15, 2015, the Parent accelerated vesting of all unvested restricted shares. As of June 30, 2015, there were no unvested restricted shares of the Parent and approximately $104,000 was recognized as incremental stock-based compensation expense due to the acceleration of the vesting dates in the three and six month periods ended June 30, 2015. Unrecognized Share-based Compensation As of June 30, 2015 and 2016, there was no unrecognized stock-based compensation expense related to the awards issued by the Parent Equity Issued by Presbia PLC Presbia Incentive Plan On January 14, 2015, the Company approved a compensation incentive plan (the “Presbia Incentive Plan”). The Presbia Incentive Plan permits the Company to grant awards of options, restricted shares, share appreciation rights, restricted share units, performance shares, performance share units, dividend equivalent rights in respect of awards and other share-based and cash-based awards, including annual and long-term cash incentive awards. A total of 1,800,000 ordinary shares were authorized for issuance under the Presbia Incentive Plan of which approximately 14,889 were available on June 30, 2016 for future grants and awards. Subsequently, on August 4, 2016, the Company’s shareholders approved an amendment to increase the shares authorized for issuance under the Presbia Incentive Plan by 400,000. The exercise price of each option award shall be determined by the Board of Directors (or a committee thereof) at the date of grant in accordance with the terms of the Presbia Incentive Plan awards, and generally vest 20% annually over a five-year period and expire no later than 10 years from the grant date. The Presbia Incentive Plan terminates on January 14, 2025, unless terminated earlier by the board of directors. Awards under the Presbia Incentive Plan may be granted to employees, directors, consultants and other persons who perform services for the Company or a subsidiary of the Company. The following table shows share-based compensation expense based upon all equity awards issued by Presbia PLC included in the Consolidated Statements of Operations and Comprehensive Loss for the three and six months ended June 30, 2016 and 2015. Three-Months Ended June 30, Six-Months Ended June 30, 2016 2015 2016 2015 Research and development $ 103 $ 81 $ 163 $ 107 General and administrative 414 424 729 1,220 Sales and marketing 26 46 67 76 $ 543 $ 551 $ 959 $ 1,403 Options The following table sets forth the Company’s option activity for the six months ended June 30, 2016: Number of Presbia Shares Weighted Average Exercise Price Per Share Aggregate Intrinsic Value Balance, January 1, 2016 1,084,583 — — Granted — — — Exercised — — — Forfeited/cancelled/expired (17,583 ) $ 8.49 — Balance, June 30, 2016 1,067,000 $ 9.74 — Vested and expected to vest, June 30, 2016 1,030,371 $ 9.76 — Exercisable, June 30, 2016 339,484 $ 9.85 — Employee Options The Company utilizes the Black-Scholes valuation model for estimating the fair value of granted stock options with the following assumptions in addition to the closing price of the Company’s ordinary shares on the date of the grant: (i) the Company estimates the expected term of the option utilizing the simplified method because of its limited history of option exercise activity and its options meet the criteria of a "plain-vanilla" option as defined by the Securities Exchange Commission (ii) due to its limited stock price volatility history, the Company uses a peer group average as permitted under Accounting Standards Codification (“ASC”) 718 consistent with the expected term of the stock option at the time of the grant and (iii) applies a risk-free interest rate based on the U.S. Treasury securities yield consistent with the expected term of the option at the time of the grant. The simplified method calculates the expected term as the average of the weighted average vesting period and contractual terms of the award. The following table presents the grant date assumptions used in the Black-Scholes model for determining the fair value of 0 and 12,500, and 0 and 1,022,500 employee options issued during the three and six months ended June 30, 2016 and 2015, respectively: Three-Months Ended June 30, 2016 Three-Months Ended June 30, 2015 Six-Months Ended June 30, 2016 Six-Months Ended June 30, 2015 Stock price per share — $ 8.67 — $ 8.89 Expected term — 6.5 Yrs. — 5.5 - 6.5 Yrs. Volatility — 84.5% — 76.8% - 84.5% Dividends — — — — Risk-free rate — 1.8% — 1.3% - 1.8% The weighted-average grant date fair values of employee options granted during the three and six months ended June 30, 2015 was $5.71 and $6.98 respectively, per share. For those options granted to employees, stock-based compensation expense was based upon the fair value of the option as of the grant-date and attributed to future reporting periods on a straight-line basis over the vesting period, or the requisite service period. The forfeiture rate, which reduces the amount of expense that is recorded reflecting the anticipated number of options that ultimately will vest in future periods, is subject to review and may be adjusted based upon experience. During 2015 and for the three months ended March 31, 2016, a 5% annualized forfeiture rate was applied. Based upon review of pre-vesting forfeitures, commencing with the second quarter of 2016, the forfeiture rate was reduced to 3%. Non-Employee Options During the three and six months ended June 30, 2016 and 2015, 0 and 54,000, and 0 and 66,500 options, respectively, were granted to non-employee consultants and medical advisors. The following assumptions were used in the Black-Scholes valuation model to determine the option fair values: Three-Months Ended June 30, 2016 Three-Months Ended June 30, 2015 Six-Months Ended June 30, 2016 Six-Months Ended June 30, 2015 Stock price per share $ 4.52 $ 8.22 $ 4.52 $ 8.22 Expected term 9.0 Yrs. 9.9 Yrs. 8.7 - 9.4 Yrs. 9.9 Yrs. Volatility 66.1% 78.8% 66.1% 78.8% Dividends — — — — Risk-free rate 1.5% 2.4% 1.5% 1.9% - 2.4% In contrast to the determination of the fair value of options granted to employees, which are determined based upon the grant-date assumptions and applying the Black-Scholes model, the fair values for non-employee options and the related stock-based compensation expense are remeasured each financial reporting period based upon the assumptions applicable on the dates in which the financial statements are prepared, which are disclosed in the preceding table. Because the performance criteria of these grants is based solely upon a requisite service period, but are subject to forfeiture if the service conditions are not met, stock-based compensation expense is determined by a straight-line attribution of the remeasured expense (mark-to-market) over the requisite service period subject to a forfeiture rate of 3%. As described in the preceding section, the annualized forfeiture rate was reduced from 5% to 3%. Restricted Shares On January 19, 2016, the Company’s board of directors approved a grant of 15,968 restricted ordinary shares of the Company, with a grant date value of $5.01 and a five-year vesting period consisting of 20% on each annual anniversary date commencing one-year following the date of grant, to Dr. Gerald Farrell upon joining the board. No additional restricted share awards were granted during the six-month period ended June 30, 2016. During the three and six month periods ended June 30, 2015, 0 and 9,270 The following table sets forth the Company’s restricted share activity for the three and six months ended June 30, 2016 and 2015: Unvested Number of Shares Weighted Average Fair Value per Share Balance, December 31, 2015 20,289 Granted 15,968 $ 5.01 Vested (1,854 ) $ 8.63 Forfeited/cancelled — Unvested, June 30, 2016 34,403 $ 6.51 Vested and expected to vest, June 30, 2016 32,549 $ 6.68 Vested, June 30, 2016 3,708 $ 8.63 Restricted Share Units On April 28, 2016, the Board of Directors approved the award of 682,500 restricted share units (“RSU” or “RSU’s” or “RSU Plan”) to officers and employees in accordance with the guidelines provided by the Presbia Incentive Plan, which includes a provision that that recipient must be employed as a condition of vesting. Generally, under an RSU program, an entity will issue new shares of its common stock, at a future date subject to a plan expiration date, to recipients of RSU’s, if and when, some or all, stated objectives under the plan are met. The Presbia RSU Plan authorizes the issuance of 20% of each recipient’s total RSU award for the first occurrence that the closing price of the Company’s ordinary shares exceed, for a period of 20 consecutive business days, price thresholds of $10.00, $15.00, $20.00, $25.00 and $30.00, respectively. The RSU Plan also provides for a one-year “wait” or service period prior to any vesting permitted under the plan. The RSU Plan has a seven-year expiration period following the date of the grant. Fair value of the 682,500 RSU’s awarded on April 28, 2016 was determined using a Monte Carlo Simulation (“MCS”) methodology, which considers the separate probabilities that each of the price thresholds or market conditions will be achieved under the RSU Plan guidelines. Each probability is weighted by its respective price threshold, or its intrinsic value, which provides the basis for an aggregate fair value of approximately $2,016,000, or a weighted average fair value of $2.95 per RSU. The Company used the following key inputs in determining the fair value using the MCS model: (i) the volatility of the entity’s common stock and (ii) the closing price of the entity’s stock as of the measurement date of the RSU award. The volatility of the Company’s stock and the closing price as of April 28, 2016 was approximately 83.9% and $3.85, respectively. In accordance with GAAP, the Company recognizes as stock-based compensation expense, using a straight-line attribution method, the aggregate fair value of $2,016,000 over future periods based upon the respective derived service periods and fair values for each of the price thresholds as provided by the MCS model. A 3% forfeiture rate was applied to account for future cancellations and forfeitures. During the three and six months ended June 30, 2016, approximately $110,000 was recorded as stock-based compensation related to the RSU Plan. No such expense was recognized in the same periods in 2015. As of June 30, 2016, 680,000 RSU’s were outstanding with none vested. Unrecognized Share-based Compensation As of June 30, 2016 and 2015, there were $4.0 million and $5.5 million, respectively, of unrecognized compensation expense related to employee and non-employee options of the Company, which collectively is expected to be recognized by the Company over the weighted average vesting period of 3.4 and 4.0 years, respectively. Unrecognized compensation expense for the same periods related to restricted shares was $177,000 and $151,000, respectively, and is expected to be recognized over the weighted average vesting periods of 4.3 and 4.7 years, respectively. As of June 30, 2016, there was approximately $1.7 million of unrecognized compensation expense with respect to the RSU’s granted in April 2016 over a weighted average remaining derived service period of 3.3 years.

Income Tax Disclosure [Abstract]
Income Taxes	(6) Income Taxes Deferred income tax assets and liabilities are recognized for temporary differences between financial statement and income tax carrying values, using tax rates in effect for the years such differences are expected to reverse. Due to uncertainties surrounding the Company's ability to generate future taxable income and consequently realize such deferred income tax assets, a full valuation allowance has been established. The Company continues to maintain a full valuation allowance against its deferred tax assets as of June 30, 2016. The impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more likely than not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. There have been no material changes in the Company's unrecognized tax benefits since December 31, 2015; and, as such, disclosures included in the Company's 2015 Annual Report on Form 10-K continue to be relevant for the period ended June 30, 2016.

Subsequent Events [Abstract]
Subsequent Event	(8) Subsequent Event On August 2, 2016, Presbia Ireland, Limited, a wholly-owned subsidiary of the Company, entered into an asset purchase agreement (the “Agreement”) with Neoptics AG (“Neoptics”) pursuant to which the Company acquired certain assets from Neoptics for an aggregate purchase price of 1.5 million Swiss Francs (approximately $1.5 million based on the exchange rate between the Swiss Franc and US Dollar on August 2, 2016) payable in three equal installments on each of August 2, 2016, December 31, 2017 and December 31, 2018. The assets being acquired include patents, pending patents, specified trademarks, equipment, inventory, technical documents and other related documents. Effective August 2, 2016, the Company shall be responsible for all expenses associated with such assets. Pursuant to the terms of the Agreement, the acquisition closed on August 2, 2016. On August 4, 2016, the Company’s shareholders approved amendments to the Presbia Incentive Plan to increase the number of ordinary shares available for awards by 400,000 ordinary shares and to approve the material terms of Section 162(m) performance goals.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation. The accompanying consolidated financial statements have been derived from the historical cost basis of the assets and liabilities, financial condition and cash flows of Presbia PLC and Presbia Ireland, Limited, both organized in Ireland, Presbia Investments, a direct subsidiary of Presbia PLC organized in the Cayman Islands, and Presbia Ireland, Limited’s subsidiaries, Presbia USA, Inc., and OPL, LLC. Presbia USA, Inc. and OPL, LLC are both entities organized in the United States, and include Presbia USA, Inc.’s subsidiaries, Visitome, Inc. and PresbiBio, LLC, both organized in the United States, and OPL, LLC’s direct and indirect subsidiaries, PIP Holdings, C.V and Presbia Cooperatief U.A., both organized in the Netherlands, and PresbiOptical LLC, organized in the United States (collectively, including Presbia PLC, the “Company”). The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company’s fiscal year ends on December 31. The entities presented in the consolidated financial statements have been under common control during the periods presented. All intercompany accounts have been eliminated in consolidation.
Basis of Presentation	Basis of Presentation. The accompanying unaudited consolidated financial statements as of June 30, 2016 and for the three and six months ended June 30, 2016 and 2015, respectively, have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting, and with the instructions to Form 10-Q and Article 8 of Regulation S-X, which do not conform in all respects to the requirements of U.S. GAAP for annual financial statements. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements presented in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2015. The accompanying condensed balance sheet as for December 31, 2015 has been derived from the audited financial statements at that date but does not include all the information and footnotes required by GAAP for complete financial statements. The results of operations for the three and six months ended June 30, 2016 are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2016, or any other period. In the opinion of management, the accompanying consolidated financial statements reflect all adjustments which are necessary for a fair presentation of the results of operations and cash flows for the periods presented. The results of operations for such interim periods are not necessarily indicative of results of operations to be expected for the full year. References to amounts in the consolidated financial statement sections are in thousands, except per share data, unless otherwise specified.
Reclassification of Prior Year Presentation	Reclassification of Prior Year Presentation. Certain prior year amounts have been reclassified for consistency with the current period presentation. These reclassifications had no effect on the reported results of operations and cash flows.
Liquidity	Liquidity The Company has incurred significant operating losses since inception and had relied on funding from Presbia Holdings (the “Parent”) to fund operations prior to its IPO on February 3, 2015. Presbia Holdings was dissolved on November 25, 2015 and ceased to be the Parent of Presbia PLC. At June 30, 2016, the Company has an accumulated deficit of $63.2 million. As the Company continues to incur losses, its transition to profitability will depend on the following: (i) the completion of its U.S. staged pivotal trial, obtaining FDA approval of its microlens and, if approval is received from the FDA, the commercialization of its product within the United States and (ii) the successful commercialization of its product in certain jurisdictions outside the United States in which the Company has market approval, including the European Economic Area. The Company may never achieve profitability, and unless and until it does, it will need to continue to raise additional capital. Management expects that existing cash as of June 30, 2016, coupled with anticipated revenues outside of the United States will be sufficient to meet the Company’s anticipated cash requirements, including funding the initial payment for the acquisition of assets from Neoptics, through the second quarter of 2017
Foreign Currency	Foreign Currency The functional currency of subsidiaries outside the United States of America is the U.S. Dollar. Transactions in foreign currencies during the year are re-measured at rates of exchange on the dates of the transactions. Gains and losses related to re-measurement of items arising through operating activities are accounted for in the statement of operations and comprehensive loss and included in general and administrative expense. Aggregate foreign exchange loss was $7,000 and 16,000 for the three and six month periods ended June 30, 2016, respectively, and aggregate foreign exchange loss was $14,000 and $0 for the three and six month periods ended June 30, 2015, respectively.
Comprehensive Loss	Comprehensive Loss Comprehensive income or loss is defined as a change in equity of a company attributable to all transactions excluding those transactions resulting from investment with owners and distributions to owners. There were no differences between net loss and comprehensive loss in the three and six month periods ended June 30, 2016 and 2015, respectively.
Deferred Offering Costs	Deferred Offering Costs During the three and six month periods ended June 30, 2015, the Company incurred approximately $0.2 million and $1.2 million, respectively, in costs related to its IPO which was completed on February 3, 2015. Upon completion of the IPO, the Company netted approximately $2.0 million in offering costs against the gross proceeds in shareholders’ deficit.
Recent Accounting Standards	Recent Accounting Standards In March 2016, the Financial Accounting Standards Board issued Accounting Standard Update (ASU) 2016-09 Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 modifies multiple provisions intended to simplify various aspects of accounting for share-based payments including income tax consequences, accounting for forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 will be effective for the Company beginning in the first quarter of 2017. The adoption of this standard is not expected to have a material impact on the Company's financial position or results of operations. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard requires lessees to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets and eliminates certain real estate-specific provisions. ASU 2016-02 will be effective for the Company in the first quarter of 2019. ASU 2016-02 will be adopted on a modified retrospective transition basis for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating the impact of ASU 2016-02 on its consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The new standard requires management to assess, at each annual and interim reporting period, an entity's ability to continue as a going concern within one year after the date that the financial statements are issued and to provide related footnote disclosures. ASU 2014-15 will be effective for the Company beginning in the first quarter of 2017. The Company is currently evaluating the impact of ASU 2014-15 on its consolidated financial statements. In June 2014, the FASB issued ASU 2014-12, Compensation - Stock Compensation (Topic 781): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period. The new standard requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. The Company adopted ASU 201-12 effective as of January 1, 2016, and the adoption of this standard had no impact on the Company's financial position or results of operations. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The new standard is based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will be effective for the Company in the first quarter of 2018 and allows for full retrospective or a modified retrospective adoption approach. The Company has not yet assessed the potential impact of ASU 2014-09 on its consolidated financial statements.
