Actual results could differ materially from those estimates and assumptions. Management considers many factors in selecting appropriate financial accounting policies and controls and in developing the estimates and assumptions that are used in the preparation of these consolidated financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of reasonable estimates of the ultimate future outcomes, and management must select an amount that falls within that range of reasonable estimates. The most significant estimates in the accompanying consolidated financial statements for the year ended December 31, 2021 relate to revenue recognition, the incremental borrowing rate related to the Company’s leased assets, and stock-based compensation expense. For the years ended December 31, 2020 and December 31, 2019, in addition to the aforementioned estimates, the fair value of the liability component of the Company’s Convertible Notes and the valuation of certain intangible assets related to the Company’s Avedro Merger were significant estimates.<span style="color:#0000ff;"> </span>Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, this process may result in actual results differing materially from those estimated amounts used in the preparation of the consolidated financial statements.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;text-indent:36pt;margin:0pt;">The Company’s consolidated financial statements as of and for the year ended December 31, 2021 reflect the Company’s estimates of the impact of the ongoing COVID-19 pandemic. The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition, including sales, expenses, reserves and allowances, manufacturing, clinical trials, research and development costs and employee-related amounts, will depend on future developments that are uncertain, including the duration and severity of the COVID-19 outbreak, the severity and transmission rates of new and more contagious/and or vaccine-resistant variants of COVID-19, and the actions taken to contain it or treat COVID-19, including the availability, distribution, rate </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt;">of public acceptance and efficacy of vaccines for COVID-19, as well as the economic impact on local, regional, national and international customers and markets. As a result, there may be changes to the Company’s estimates regarding the impact of COVID-19 in future periods. </p>

The Company maintains deposits in federally insured financial institutions in excess of federally insured limits and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. Additionally, the Company has established guidelines regarding investment instruments and their maturities </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt 0pt 9pt 0pt;">which are designed to maintain preservation of principal and liquidity. The Company believes that the concentration of credit risk in its accounts receivable is mitigated by its credit evaluation process, relatively short collection terms and the level of credit worthiness of its customers. During the years ended 2021, 2020 and 2019, none of the Company’s customers accounted for more than 10% of revenues. </p>
