Modified head inversion technique for pterygium and pseudopterygium surgery combined with keratopigmentation

Abstract

Purpose: We describe a single sitting modified technique of pterygium surgery along with corneal tattooing for combined cosmetic rehabilitation in eyes with corneal opacity and pterygium or pseudopterygium. Method: Five patients with corneal opacity due to healed keratitis/optically failed therapeutic grafts along with pterygium or pseudopterygium underwent combined pterygium surgery by head inversion technique and corneal tattooing in the same sitting. All patients had no visual prognosis in that eye and surgery was indicated for cosmetic reasons only. Results: At 6 months follow up no complications of pterygium surgery like recurrence, thinning, dellen, infections were noted in any patient. The dye was retained in the cornea and the cosmetic rehabilitation was excellent in all patients. Discussion: Corneal tattooing combined with pterygium/pseudopterygium surgery can be performed in a single sitting with this novel technique in eyes with no visual potential. This is particularly suitable for eyes with limbal stem cell deficiency or large pterygia/pseudopterygia where conjunctival autograft is not advisable. These patients are often apprehensive for an allograft from their only seeing other eye
