Method for fabricating intraocular lens with peripheral sharp edge

A method of forming the sharp posterior edge of an intraocular lens (IOL) by using a laser to cut or ablate the edge of the IOL substantially cylindrically around the lens axis. The IOL is manufactured with a radius slightly larger than the final lens radius, polished, and then trimmed with the lase...

Zusammenfassung:A method of forming the sharp posterior edge of an intraocular lens (IOL) by using a laser to cut or ablate the edge of the IOL substantially cylindrically around the lens axis. The IOL is manufactured with a radius slightly larger than the final lens radius, polished, and then trimmed with the laser to produce the desired final lens shape with the sharp posterior edge. The cutting or ablation process is programmed to avoid damaging the haptic extensions of the lens. The use of a laser cutting or ablation process simplifies and accelerates the production of the lens.
