RESULTS OF PENETRATING KERATOPLASTY IN ANIRIDIA

Eight aniridic patients with bilateral corneal scarring, vascularization, or edema underwent corneal transplantation in one or both eyes (11 eyes). Follow-up ranged from eight months to 5 1/2 years (average, three years). Six of 11 eyes (55%) had at least a two-line improvement in visual acuity and eight of 11 (73%) had at least one line of improvement. Best-corrected visual acuity was 20/200 or worse in nine of 11 eyes (82%), however. Postoperative complications included whorl keratopathy, persistent epithelial defects, central subepithelial scarring, peripheral vascularization with pannus, and graft rejection. Glaucoma was well controlled medically but five of nine patients (56%) with preexisting glaucoma needed an increase in medication for intraocular pressure control. Graft rejection occurred in seven of 11 eyes (64%) and three of these eyes required repeat transplantation.
