Abstract

PURPOSE:

To study the results of the modified osteo-odonto keratoprosthesis (MOOKP) surgery in bilateral end-stage ocular surface disorders.

METHODS:

The MOOKP surgery is performed as a routine in 3 stages. Stage 1A involves removal of the iris and anterior vitrectomy with a corneal transplant if indicated. Stage 1B + 1C usually performed simultaneously involves harvesting the buccal mucosa and transplanting it onto the ocular surface along with fashioning of the osteo-odonto alveolar lamina. Stage 2 involves transplanting the osteo-odonto alveolar lamina to the eye 3 months later.

RESULTS:

The MOOKP surgery was completed in 50 eyes of 47 patients with a mean follow-up of 15.38 months (range: 1-54 months). Anatomic success was achieved in 96% of the eyes. Functional success of visual acuity > or = 20/60 was noted in 66% of eyes. Complications included oroantral fistula (6%), trophic mucosal alterations (8%), lamina exposure (central 6% and peripheral 8%), mucous membrane overgrowth (2%), hypotony (2%), expulsion of optic cylinder (4%), endophthalmitis (2%), glaucoma (20%), sterile vitritis (6%), and retinal detachment (2%).

CONCLUSIONS:

MOOKP is the keratoprosthesis of choice in bilateral end-stage ocular surface disorders in the Indian subcontinent. Complications do occur and have to be recognized and treated early.
