Prolonged exposure of intraocular lens implant with preservation of globe integrity and visual function

A 70-year-old woman had corneal ulcer and melting after complicated cataract surgery with polymethylmethacrylate lens implant insertion. A conjunctival flap was initially used to cover the defect with a plan to perform keratoplasty later. Fifteen months postoperatively, she presented with total absence of central corneal tissue and iris and exposure of the implant. The eye was not inflamed, painful, or hard on palpation and visual acuity was counting fingers at 3 m. The preservation of globe integrity despite exposure of the polymethylmethacrylate implant implies a stable adhesion between polymethylmethacrylate and residual corneal tissue and may prove useful in keratoprosthesis design.
