Abstract
A method for polishing targeted areas of an IOL while leaving other areas unpolished such as sharp posterior edges designed to inhibit PCO. In the preferred embodiment, the polishing method utilizes a stream of polishing agent directed at the IOL which is mounted to a holder during the polishing operation. In this manner, only the targeted areas of the IOL polished while the other areas remain unpolished and sharp as intended. The method is suitable for in-line automated IOL manufacturing.
