Abstract:
1. A process of fabricating an intraocular lens (IOL), the process comprising: providing a blank lens having a center lens optical portion, a surrounding lens portion, and at least one haptic coupled to the surrounding lens portion, roughening the peripheral edge surface such that the peripheral edge surface has a glare-reducing rough surface with a surface roughness level of about Ra 180 μ in; the rough surface having a Gaussian distribution width sigma of at least 1 when illuminated by an incident light beam, and scattering data from the illuminated rough surface is fitted to a Gaussian distribution model, the incident light beam having a wavelength of 633 nanometers and illuminating the surface at a 55 degree incident light angle; and wherein the center lens optical portion has no surface roughening applied thereto.
