ABSTRACT:
A posterior chamber intraocular lens implant having improved fixation where there is no posterior capsule remaining to serve as a fixation platform. In addition to ciliary sulcus haptics, the lens implant has two oppositely disposed loops which serve as suture sites for the suturing of the implant directly to the iris. The loops, which are only so large so as to accommodate a 9-0 size suture thread, extend anteriorly from the optical lens to act as a cushion between the lens and the iris of the eye, and radially such that they align with the striae of the iris when the implant has been positioned within the eye, whereby inflamation of the iris is minimized.
