Subsequent Events [Abstract]
Subsequent Events	15. Subsequent Events On July 26, 2022, the Center for Medicare & Medicaid Services (“CMS”) published in the Federal Register the calendar year (CY) 2023 Medicare Hospital Outpatient Prospective Payment System (“OPPS”) and ASC Payment System Proposed Rule (“Proposed Rule”). If the Proposed Rule is finalized, in the relevant part, without changes, it would result in loss of pass-through related separate payment for DEXYCU, when furnished in hospital outpatient department settings reimbursed by Medicare. This would reduce the amount of Medicare reimbursement provided to the Company’s DEXYCU customers and, if finalized without changes, result in a significant reduction in the Company’s DEXYCU product revenues (see Note 3). Furthermore, a significant reduction in the Company’s DEXYCU product revenues will result in a material impairment of the Company’s net intangible asset related to DEXYCU which has a carrying value of $21.5 million at June 30, 2022 (see Note 5). The Proposed Rule is currently in a comment period which ends on September 13, 2022. A Final Rule is expected to be issued in early November 2022. In the Final Rule, CMS may adopt or modify the Proposed Rule’s proposals related to DEXYCU. If the Proposed Rule’s proposals related to DEXYCU are finalized, they would be effective on January 1, 2023. The Company will monitor the status of the Proposed Rule and evaluate the impact on its operations, cash flows, intangible asset and its DEXYCU inventory balances when the rule is finalized. No adjustments have been made to the Company’s June 30, 2022 financial statements as a result of the Proposed Rule.
