Posterior synechiae in extracapsular cataract extraction with posterior-chamber intraocular lenses.

Posterior synechiae formation was studied in 294 consecutive cases of extracapsular cataract extraction with posterior-chamber intraocular lens implantation. The synechiae are mainly a cosmetic blemish and may hinder future pupillary dilation. Formation can be reduced by elimination of the iridectomy, elimination of routine mydriatic drops, and minimization of iris trauma at the time of surgery.
