ABSTRACT:
The capsular adhesion preventing ring includes a wristband-like member having a diameter larger than that of an anterior capsular opening. The ring has multiple engaging holes and multiple guide slots formed through the circumferential wall of the ring, and each guide slot extends from the lower or upper rims of the ring to a corresponding engaging hole. In this ring, each guide slot may have a slant angle to the rim of the ring, be opened to a corresponding engaging hole along a cutting line of the hole, and an engaging protrusion may be formed between the guide slot and engaging hole. The direction of the engaging holes and guide slots from inside to outside of the wall may be almost parallel to the direction of a corresponding part of the loops of the intraocular lens that is inserted into the capsular bag before the insertion of the ring. This ring prevents adhesion of the capsular bag, which is adopted to prevent adhesion of the anterior and posterior lens capsules at the incised edge of the anterior capsule after cataract surgery, and also prevents lens regeneration, so as to prevent secondary cataracts.
