A stitch in time saves my (ne) (vision).

BACKGROUND: Corneal melt with iris prolapse is a rare complication of autoimmune diseases, especially rheumatoid arthritis.

PURPOSE: To highlight a challenging case of a peripheral ulcerative keratitis (PUK) with corneal melt and iris prolapse in a patient's only eye.

SYNOPSIS: A 56-year-old Asian Indian male presented with blurring of vision in the right eye and was diagnosed with cataract. He was a known type 2 diabetes mellitus and a rheumatoid arthritis patient and was not on treatment. He had been previously diagnosed with PUK in the left eye and was lost to follow-up due to coronavirus disease 2019 (COVID-19) after therapeutic penetrating keratoplasty and lost his vision in that eye. Cataract surgery in the right eye was done under cover of immunosuppression. Subsequently, he developed PUK and was treated with a glue and bandage contact lens. Again, he was lost to follow-up and then presented a few months later with corneal melt with iris prolapse in the right eye. We describe in the video the surgical and medical challenges and successful salvage of both the eyeball and the vision.

HIGHLIGHTS: Highlights include the following: 1. A rare case of corneal melt with iris prolapse. 2. Demonstration of surgical technique of patch graft. 3. Anterior segment optical coherence tomography before and after the procedure.
