ABSTRACT:
The invention contemplates an intra-ocular-lens structure for implantation in place of a cataracted natural lens. The construction features a lens element of requisite prescription power, and multiple-sheet fenestrated haptic structure engaged to the lens extends radially outwardly for stabilizing contact with wall features of the anterior chamber of the eye. The haptic sheets are in permanently bonded laminated relation to each other, with circumferentially continuous supporting engagement to front and back sides of the rim of the lens element.
