Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Condensed Consolidated Balance Sheet as of May 26, 2024, which has been derived from audited financial statements, and the accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments (consisting of normal recurring accruals) have been made which are necessary to present fairly the financial position of the Company at November 24, 2024, and the results of operations and cash flows for all periods presented. Although the Company believes that the disclosures in these financial statements are adequate to make the information presented not misleading, certain information normally included in financial statements and related footnotes prepared following GAAP have been condensed or omitted per the rules and regulations of the Securities and Exchange Commission (the “SEC”). The accompanying financial data should be reviewed in conjunction with the audited financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended May 26, 2024.
Fiscal Period	The Company’s fiscal year is the 52- or 53-week period that ends on the last Sunday of May with quarters within each year ending on the last Sunday of August, November, and February; however, in instances where the last Sunday would result in a quarter being 12-weeks in length, the Company’s policy is to extend that quarter to the following Sunday. A 14th week is included in the fiscal year every five or six years to realign the Company’s fiscal quarters with calendar quarters. The results reported in these interim condensed consolidated financial statements are not necessarily indicative of the results that may be reported for the entire year.
Reclassification	During the second quarter of 2025, the Company changed the basis of presentation for certain items to improve the usefulness of the financial statements, none of which had a material effect to any of the periods presented: (i) in Note 8 – Inventories, the Company previously presented certain adjustments used to state inventory at net realizable value as a standalone caption titled "inventory reserve" and now presents those adjustments directly to raw materials; (ii) in the balance sheet and Note 9 – Property, Plant and Equipment, net, the Company previously presented the carrying value of certain types of software not yet placed into service as a component of other long-term assets and now presents those within the construction in process category of property, plant and equipment, with additions to that software presented as purchases of property, plant and equipment on the statement of cash flows; (iii) in the statement of cash flows, non-cash interest for periods ended in fiscal year 2024 were previously presented within both depreciation and amortization as well as the change in working capital and are now presented as a standalone caption for non-cash interest; and (iv) on the balance sheet, certain types of accrued liabilities were previously presented as accrued other liabilities and are now presented as accrued compensation, with changes to those liabilities reclassified to the applicable lines within operating activities on the statement of cash flows.
Statement of Comprehensive Income or Loss	Statement of Comprehensive Income or Loss In accordance with Financial Accounting Standards Board Accounting Standard Codification Topic 220, Comprehensive Income, a statement of comprehensive income has not been included as the Company has no items of other comprehensive income or loss. Comprehensive income or loss is the same as net income or loss for all periods presented.
Basis of Consolidation	Basis of Consolidation The condensed consolidated financial statements are presented on the accrual basis of accounting in accordance with GAAP and include the accounts of the Company and its subsidiaries. All material inter-company transactions and balances have been eliminated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. The accounting estimates that require management’s most significant and subjective judgments include revenue recognition; recognition and measurement of current and deferred income tax assets and liabilities; the recoverability assessment of inventories; the valuation and recognition of stock-based compensation; and the valuation of the debt derivative liability. These estimates involve the consideration of complex factors and require management to make judgments. The analysis of historical and future trends can require extended periods of time to resolve and are subject to change from period to period. The actual results may differ from management’s estimates.
Reportable Segments	Reportable Segments The Company operates as one reportable segment. This is based on the objectives of the business and how our chief operating decision maker, the President and Chief Executive Officer, regularly reviews and manages the business, monitors operating performance and allocates resources.
Concentrations of Risk	Concentrations of Risk Cash and trade accounts receivable are financial instruments that potentially subject the Company to concentrations of credit risk. Our Company policy limits, among other things, the amount of credit exposure to any one issuer and to any one type of investment, other than securities issued or guaranteed by the U.S. government. The Company maintains cash in U.S. bank accounts, the balance of which may at times exceed the federally insured limit.
Per Share Information	Per Share Information Accounting guidance requires the presentation of basic and diluted earnings per share. Basic earnings per share is computed using the weighted average number of common shares outstanding during the reporting period. Diluted earnings per share reflects the potential dilution as if securities or other contracts to issue the Company’s common stock, par value $0.001 per share (“Common Stock”) were exercised or converted into Common Stock. The Company’s diluted common equivalent shares consist of convertible preferred stock, stock options, restricted stock units (“RSUs”), and performance share units (“PSUs”). Dilution related to stock options, RSUs and PSUs is calculated using the treasury stock method, which includes the assumed repurchase of common shares from cash received upon stock option exercises, and unrecognized compensation expense. The potential dilutive effect of the Convertible Preferred Stock is calculated using the if-converted method assuming the conversion as of the earliest period reported or at the date of issuance, if later, but are excluded if their effect is anti-dilutive.
Fair Value Measurements	Fair Value Measurements The Company uses fair value measurement accounting for financial assets and liabilities and for financial instruments and certain other items measured at fair value. The Company has not elected the fair value option for any of its other eligible financial assets or liabilities. Applicable accounting guidance establishes a three-tier hierarchy for fair value measurements, which prioritizes the inputs used in measuring fair value as follows: •Level 1 – observable inputs such as quoted prices for identical instruments in active markets. •Level 2 – inputs other than quoted prices in active markets that are observable either directly or indirectly through corroboration with observable market data. •Level 3 – unobservable inputs in which there is little or no market data, which would require the Company to develop its own assumptions.
Related Party Transactions	Related Party Transactions The Company has reflected related party balances on the face of its financial statements beginning in the period which Alcon Research, LLC (“Alcon”) became a related party, which was as of May 22, 2023 at the time Alcon provided financing to the Company. Prior to providing financing, and continuing subsequently, Alcon was a customer of the Company.

Basis of Consolidation

The condensed consolidated financial statements are presented on the accrual basis of accounting in accordance with GAAP and include the accounts of the Company and its subsidiaries. All material inter-company transactions and balances have been eliminated.

The actual results may differ from management’s estimates.

Reportable Segments

The Company operates as one reportable segment. This is based on the objectives of the business and how our chief operating decision maker, the President and Chief Executive Officer, regularly reviews and manages the business, monitors operating performance and allocates resources.

Concentrations of Risk

Cash and trade accounts receivable are financial instruments that potentially subject the Company to concentrations of credit risk. Our Company policy limits, among other things, the amount of credit exposure to any one issuer and to any one type of investment, other than securities issued or guaranteed by the U.S. government. The Company maintains cash in U.S. bank accounts, the balance of which may at times exceed the federally insured limit.

Applicable accounting guidance establishes a three-tier hierarchy for fair value measurements, which prioritizes the inputs used in measuring fair value as follows:

•Level 1 – observable inputs such as quoted prices for identical instruments in active markets.

•Level 2 – inputs other than quoted prices in active markets that are observable either directly or indirectly through corroboration with observable market data.

•Level 3 – unobservable inputs in which there is little or no market data, which would require the Company to develop its own assumptions.

Related Party Transactions

The Company has reflected related party balances on the face of its financial statements beginning in the period which Alcon Research, LLC (“Alcon”) became a related party, which was as of May 22, 2023 at the time Alcon provided financing to the Company. Prior to providing financing, and continuing subsequently, Alcon was a customer of the Company.
