Small-incision cataract surgery using the Perrin intraocular cataract scissors and forceps.
An original operative technique for performing extracapsular cataract extraction through a small incision is described. The technique is both inexpensive and simple to perform. Intraocular cataract scissors are used to bisect the nucleus of the cataractous lens, and each of the halves of the bisected nucleus is removed with intraocular cataract forceps. Both the scissors and the forceps have been specifically designed for this task. The incision size of 7.5 mm allows insertion of currently available intraocular lenses. During the procedure viscoelastic is used to protect intraocular structures, in particular the corneal endothelium and the posterior capsule.
