摘要：
Embodiments of the present invention provide an intraocular lens with an optic zone having a first surface topology and a haptic zone having a second surface topology. The surface roughness of the haptic zone may be greater than the surface roughness of the optic zone. The surface topology of the optic zone may have a first surface geometry and the surface topology of the haptic zone may have a second surface geometry. The first and second surface geometries may retain lubrication fluid in a space formed therein. The haptics formed by the manufacturing process may have a reduced ability to adhere to the optic zone, such as when the lens is folded or advanced through a cannula.
