摘要：
Disclosed is an intraocular lens with feature to reduce the adherence of the haptic zone to the optic zone. The lens comprises an optic zone, configured to replace a natural lens or to correct a malady in the natural lens of an eye, having a first surface topology, and a haptic zone, configured to hold the intraocular lens in the eye, having a second surface topology. The second surface topology reduces the ability for the haptic to adhere to the optic zone, by the second surface topology comprises one or more continuous geometry features over the second surface topology. The first surface topology comprises a first surface roughness and the second surface topology comprises a second surface roughness at least two times greater than the first surface roughness. The haptic is configured to hold the intraocular lens in a desired position and orientation, and configured to be folded inside the optic zone as the intraocular lens is compressed for insertion into the eye and wherein the second surface topology of the haptic forms a space between the haptic and the optic zone during insertion of the lens into the eye. The optic zone is configured to unfold in the eye.
