ABSTRACT:
The invention contemplates improved techniques for making lens implants for use in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens. The lens of the invention is particularly adapted for posterior-chamber implantation, with position stability derived from the inner wall of the natural-lens sac (from which cataracted material has been removed). A manipulative tool in combination with the lens assembly (1) provides safe stabilizing support during storage and transit prior to the surgeon's access for operative use, and (2) is configurated to facilitate operative placement of compliant retaining feet within the sac, permitting posterior-chamber positioning of the lens prior to tool removal.
