Abstract
Apparatus and method for cutting an IOL optic from an IOL blank whereby the resultant IOL optic has a square edge and the cutting is performed in a combined linear and rotational cutting movement. In another aspect, an IOL optic is provided which includes a square edge and helically shaped striations formed therein to help reduce glare.
Claims11
A method for cutting an IOL optic having opposite anterior and posterior surfaces and a peripheral wall extending therebetween out of an IOL blank, said method comprising the steps of:
- a) providing a generally circular cutting edge;
- b) providing a lens press having a generally circular lens-engaging end;
- c) positioning said IOL blank between said generally circular cutting edge and said generally circular lens-engaging end of said lens press;
- d) moving said lens press and said cutting edge toward one another in a rotational translation with said cutting edge rotationally cutting through said IOL blank and thereby forming said IOL optic.
9-19. (canceled)
A method of cutting an intraocular lens blank to form an intraocular lens optic comprising the steps of:
- a) providing a generally circular cutting edge in the shape and size of the outer-most peripheral wall of the IOL optic to be formed;
- and
- b) cutting the intraocular lens blank with the cutting edge in a simultaneous linear and rotational movement to form the intraocular lens optic.
The method of claim 18, and further comprising the step of forming generally helically shaped striations in said peripheral wall.
