Patent ID: 8012203

Claim:
An intraocular lens, comprising: a center lens portion for focusing incoming light toward the retina of an eye; a surrounding lens portion having an anterior surface, a posterior surface, and a peripheral edge surface, said peripheral edge surface intersecting at least one of said anterior and posterior surfaces; a glare-reducing rough surface disposed on the surrounding lens portion, the rough surface having a surface roughness level of about Ra 180 μin, 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 at least one haptic coupled to the surrounding lens portion; wherein the rough surface is disposed on the peripheral edge surface, and the center lens portion having no surface roughening applied thereto.
