An intraocular lens for implant in the anterior chamber has four fixation members extending from a lens body with the lens body having curved, opposed end peripheral edges and curved side peripheral edges, the radius of curvature of the end peripheral edges being less than the radius of curvature of the side peripheral edges and the fixation members extending from the junctions of the end and side peripheral edges and having continuously curved proximal legs, junction portions and distal legs terminating at footplates to be received in the angle of intesection of the cornea and iris such that the fixation members flex along their entire length in response to forces applied to the footplates.
