Allogenic Simple Limbal Epithelial Transplantation: An Approach to Bilateral Recurrent Pterygia and Limbal Stem Cell Deficiency

Abstract

A 44-year-old man presented with bilateral total limbal stem cell deficiency after multiple failed surgeries for recurrent pterygia in both eyes over the last 11 years. His best corrected visual acuity (BCVA) in both eyes at the time of presentation was hand movement, projection of rays accurate. Owing to bilateral involvement, allogenic simple limbal epithelial transplantation (Allo SLET) was performed in the right eye. The limbal biopsy was taken from the wife of the patient. Complete ocular surface epithelialization was achieved in 26 days. The patient has completed 15 months of postoperative follow-up with stable ocular surface and BCVA 6/12 in the RE. He is on systemic and topical immunosuppressants with no side effects to date.
