Реферат: An intraocular lens includes an optic having an anterior optic surface, a posterior optic surface, and an optic edge extending between the anterior optic surface and a posterior optic surface. The optic edge includes a convex portion extending from a periphery of the anterior optic surface and a flat portion extending from a periphery of the posterior optic surface such that a corner edge is formed between the optic edge and the posterior optic surface. The flat portion intersecting the convex portion to form the optic edge. Such an optic edge may eliminate glare or other undesired effects that adversely impact quality of vision.
