Scleral cyst formation following extracapsular cataract extraction

Abstract

Two patients who underwent extracapsular cataract surgery through corneal incisions developed scleral cysts 2 and 6 years later, respectively. The cysts involved the sclera without extension into the cornea or anterior chamber. To prevent further thinning of the sclera, only the anterior walls were excised and the posterior walls were mechanically debrided using alcohol and sponges. Histopathologic examination supported the clinical diagnosis of scleral cysts. No recurrence was seen. Scleral cyst formation may be encountered as a late complication of cataract surgery. Excision of the anterior wall coupled with removal of the epithelial lining of the posterior wall with alcohol may considerably lessen the likelihood of recurrence.
