Transscleral sulcus fixation of a small-diameter iris-diaphragm intraocular lens in combined penetrating keratoplasty and cataract extraction for correction of traumatic cataract, aniridia, and corneal scarring

Abstract

We present the case of a 36-year-old Hispanic man who presented with photophobia and hand motion acuity from a lacerated cornea. Primary repair had been performed 13 years earlier. In addition to a densely scarred cornea and a fibrotic, partially resorbed cataract, more than 300 degrees of iris loss was noted. The patient was treated with penetrating keratoplasty, cataract extraction, and implantation of a transsclerally fixated, small-diameter aniridic intraocular lens (IOL). Despite the significant iris loss, a small-diameter IOL was chosen over a standard larger aniridic IOL to allow safer, more controlled insertion through an 8.0 mm trephination. Following surgery, the visual acuity improved to 20/25 with no symptoms of glare or photophobia.
