Abstract Details



Purpose:

The Modified Osteo Odonto Keratoprosthesis (MOOKP) provides the best form of rehabilation for eyes with end stage Ocular surface disease in terms of vision, stability and longivity

Setting:

Bombay Hospital and Medical Research Centre, Mumbai, India

Methods:

10 patients in the age group of 16-56 years underwent MOOKP between January 2008 to January 2010. The indications were steven johnson syndrome, Multiple failed penetrating grafts, trauma, chemical burns and Corneal decompensation with silicone oil .After a thorough Pre operative assesment, the surgery was conducted over a period of 3 months. Stages I A- mucous membrane grafting. I B - preparation of osteo dental acrylic lamina ( ODAL). Stage IIA- preparation of implant. Stage IIB- implantation of ODAL onto the corneal opening. Post op management, 3 months follow up, visual acuity, visual fields, IOP, refraction, Optic disc evaluation and 3 D CT scan at 2 years were done

Results:

3 eyes were lost at 15, 21 and 33 months due to mucosal melts, retinal detachment and ODAL extrusion. 1 eye was abandoned after stage I. 6 eyes mantained vision till date. BCVA achieved was 20/30, N6 and worst achieved was hand movements. Most common complication were mucous membrane thinning, vitritis and retinal detachment. 3D CT Scan was done at 24 months in 5 patients. 1 patient showed severe bone resorption

Conclusions:

MOOKP has given stable vision in 50% of the patients for about 4 years. The quality of vision was found t o be satisfactory
