Abstract
An intraocular lens configured to be implanted in the cornea from the posterior aspect. The lens has an optic and a pair fixation members extending outward therefrom. One of the fixation members includes a single enlarged foot, while the other fixation member has two bifurcated feet. The fixation members are sized and shaped to fix within tunnels formed in the cornea. A method of the invention includes forming tunnels in the stroma layer of the cornea, and positioning the fixation members in the tunnels. The tunnels may be formed from outside or inside the cornea. The method may include inserting the folded intraocular lens into the anterior chamber, permitting the lens to unfold, inserting the fixation member with the enlarged foot in one of the tunnels, and bending the two bifurcated feet of the other fixation member together so as to fit within the other tunnel.
