Patent ID: 7811319

Claim:
An intraocular lens, comprising: a center lens portion for focusing incoming light toward the retina of an eye; a surrounding lens portion; and a rough surface disposed on the surrounding lens portion for reducing glare due to non-focused light directed toward the retina from said intraocular lens, 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; wherein said surrounding lens portion includes a peripheral edge surface intersecting at least one of an anterior and a posterior surface to form a corner therebetween, the corner and the center lens portion having no surface roughening applied thereto, the surface roughness being disposed on one or more of the anterior and posterior surfaces.
