METHOD OF MAKING AN OCULAR IMPLANT

摘要

A method is provided for making a mask (6200) configured to improve the depth of focus of an eye of a patient. A substrate (6000) is provided with a mask forming feature (6008). The mask forming feature comprises an annular surface (6020) that has a curved profile (6016) that corresponds to the curvature of a corneal layer of the eye. A release layer (6080) is formed on the annular surface. A mask layer (6100) of a biocompatible metal is formed above the release layer. The mask layer is separated from the substrate.
