On April 24, 2024 Alcon Canada was notified of an increase in customer reports of dull or knife not sharp for specific ClearCut® Dual Bevel Sideport and A-OK® Corneal/Scleral V-lance ophthalmic knives. Knives that do not meet customer sharpness expectations could result in the use of increased penetration force during surgery when compared to a sharper knife. The initial scope was based on an observed in-process data shift for a specific knife family. Based on the new complaint signal, out of an abundance of caution, Alcon is now including all blades, of all models, made August 1, 2023 to March 2, 2024. Recall start date: April 26, 2024
