Boston Type I Keratoprosthesis for Visual Rehabilitation in a Patient With Gelatinous Drop-Like Corneal Dystrophy

Abstract

To report the use of a Boston type I keratoprosthesis as a primary penetrating procedure to treat gelatinous drop-like corneal dystrophy (GDLD), with presentation of pathologic findings and discussion of other surgical options. A 49-year-old woman with GDLD in both eyes and history of recurrent corneal opacification following multiple superficial keratectomies is presented. Best corrected visual acuity (BCVA) was counting fingers in both eyes. A Boston type I keratoprosthesis was implanted in her left eye after optical iridectomy, extracapsular cataract extraction, and anterior vitrectomy. The surgery was uneventful and one month after surgery, best corrected vision improved to 20/20 and has been maintained for a period of more than 14 months. No post-operative complications were observed. Histopathology of the corneal specimen is presented. GDLD is a rare disorder of amyloid deposition. Recurrence of this condition following surgery is extremely common. Boston type I keratoprosthesis is an effective procedure for restoring vision in affected patients.
