ABSTRACT:
An IOL implantable in an eye including an optic having an optical portion for directing light toward the retina of the eye and a cell barrier portion for inhibiting cell growth from the eye in front of or in back of the optical portion. The cell barrier portion circumscribes the optical portion, is incapable of focusing light on the retina and includes an irregularly configured structure, for example, irregular grooves. At least one elongated fixation member is coupled to the optic for use in fixing the optic in the eye.
