Abstract
Apparatus and methods for protecting the edge geometry of an intraocular lens during polishing are disclosed. The apparatus comprises a protective device having a cavity configured to receive the lens and an annular peripheral portion for surrounding and protecting at least one edge corner of the lens. In one embodiment, the peripheral portion has a constant inner diameter and receives the lens in an interference fit. In another embodiment, the lens is trapped between flanges which extend radially inwardly from the peripheral portion. A lens that is encased in the protective device will have a polished central portion and an unpolished peripheral portion after the polishing process has been completed and the protective device has been removed.
Claims8
A combination comprising:
- an intraocular lens having an anterior surface, a posterior surface, and a peripheral edge having at least a portion susceptible to rounding;
- and
- an apparatus positioned relative the lens for protecting at least the susceptible portion of the peripheral edge during polishing of the anterior and posterior surfaces.
