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.一種人工晶狀體，包括光學器件，所述光學器件具有光學器件前表面、光學器件後表面、以及在所述光學器件前表面與所述光學器件後表面之間延伸的光學器件邊緣。所述光學器件邊緣包括：凸形部分，所述凸形部分從所述光學器件前表面的周邊延伸；以及平坦部分，所述平坦部分從所述光學器件後表面的周邊延伸，使得在所述光學器件邊緣與所述光學器件後表面之間形成拐角邊緣。所述平坦部分與所述凸形部分相交以形成所述光學器件邊緣。這種光學器件邊緣可以消除眩光或對視覺品質有不利影響的其他不希望的效應。
