Abstract

Transscleral suture fixation of posterior chamber lenses is preferred to angle-supported anterior chamber lenses in cases of complicated cataract surgery with loss of the capsule. One of the disadvantages of suture fixation is the time needed to fix the suture to the haptic of the intraocular lens and to the sclera. Up to now it has been necessary for sutures to be tied separately to the haptic of the posterior chamber lens. With a modified one-piece PMMA posterior chamber lens, which has positioning holes at the vertex of the haptic (Morcher G 48), this is no longer necessary. Using a loop technique, it is possible for a specially designed single-arm loop suture (Ethicon X900G/STC-6) to be fixed safely to this new lens without any knots. Fixation of the sutures can thus be performed more easily and quickly, and there is no more danger of the suture slipping off the haptic. For the first time it has become possible to fix the sutures to the haptic without putting the intraocular lens down in the perioperative field. Reducing the manipulation time on the intraocular lens may also reduce the risk of intraoperative contamination.
