YAG laser resection for the membrane on anterior surface of intraocular lenses.
The results and methods of YAG laser resection for the membrane forming postoperatively on the anterior surface of intraocular lens (IOL) in 33 eyes (31 cases) were reported. A monomode single pulse YAG laser was used to do a circular incision along the pupilar margin and blow it up. A multimode defocus burst was used to peel off the shrunk flap from the lens surface. The membrane in 27 eyes (81.8%) was completely removed in the first resection. The mean burst number was 49.2 +/- 26.3. The average energy of each burst was 1.3 mJ and the average total energy of each treatment was 62.1 +/- 37.1 mJ. Except 3 eyes with little blood oozing from iris near the pupilar margin, 4 eyes having foggy spots on IOL surface and 2 eyes with mild transient increased intraocular pressure (IOP) after resection, there were no other complications. The resection is safe and effective, could be instead of the second operation for unabsorbable organized membranes or the membrane causing blockage glaucoma, could accelerate the recovery of visual acuity and shorten or substitute medical treatment for thick membranes.
