US Optics Company's single-focus crystal has had its selected qualification for centralized procurement cancelled.

On August 22, the drug regulatory department conducted product quality supervision and spot checks on the Acrylic Aspheric Intraocular Lens selected in the fourth batch of national centralized procurement of high-value medical consumables organized by the United States' CooperVision. It was found that some of the artificial lens products of the company did not meet the standard requirements for "diopters", and legal actions will be taken accordingly. The joint procurement office has decided to revoke the qualification for the selected single-focus lens from CooperVision.
