TÍTULO:
VISUAL REHABILITATION WITH BOSTON TYPE I KERATOPROSTHESIS IN A PUBLIC REFERRAL CORNEA CENTER

OBJETIVO:
To report the experience of the Federal University of São Paulo, Brazil, in performing Boston keratoprosthesis Type 1 implantation in the developing world.

MÉTODO:
We analyzed 30 eyes of 30 patients who underwent Boston Type 1 keratoprosthesis surgery between 2008 and 2012 in a prospective interventional study. Preoperative, perioperative, and postoperative parameters were analyzed, including visual acuity (VA), keratoprosthesis stability, and postoperative complications.

RESULTADOS:
Preoperative diagnoses were failed grafts in 16 eyes (53.33%), chemical injury in 10 eyes (33.33%) and Stevens-Johnson syndrome in 4 eyes (13.33%). Also, 16 eyes (53.33%) had preoperative glaucoma. Preoperative best-corrected VA ranged from 20/400 to light perception. With an average follow-up of 32 months (range, 1–55), postoperative vision improved to >20/200 in 24 eyes (80%). Postoperative VA was statistically improved compared to the preoperative measurement during all postoperative follow-ups (up to 36 months). During the follow-up period (32 months), retention of the initial keratoprosthesis was 93.3%. The incidence of retroprosthetic membrane was 26.66%. Progression of glaucoma occurred in 7 of 16 eyes (43%). Three patients developed glaucoma after keratoprosthesis implantation.

CONCLUSÕES:
Performing Boston Type 1 keratoprosthesis in a developing country is a viable option after multiple keratoplasty failures and conditions with a poor prognosis for keratoplasty. Our experience appears similar to major reports in the field from investigators in developed countries. Adjustments to postoperative management must be considered according to the particular location.
