Patent

CA 2427768

A unique anterior chamber phakic lens and methods for implantation are provided. The foldable optical zone portion of the lens is secured to a pair of diametrically opposed haptic members extending outwardly from the optical zone periphery to the angle of the eye. Each of the haptic members comprises an elongated arm portion and a distal arcuate portion with an inward curvature having an abraded surface. The inventive phakic lens is angle fixated by inducing a slight amount of scar tissue where the distal ends of lens haptics rest in the angle. Accordingly, the unique phakic lens and implantation methods minimize lens related etiology such as iris chafing, glaucoma, uveitis, distortion of the iris, and/or corneal decompensation.
