Abstract Details

Purpose:

To describe the visual outcome, anatomical retention, complications and outcomes of patients who underwent type 1 Boston keratoprosthesis (B-Kpro) after chemical burns in the Dominican Republic.

Setting:

Massachusetts Eye and Ear Infirmary, Harvard Medical School, Boston, United States of America Hospital Elías Santana, Santo Domingo, República Dominicana

Methods:

A retrospective review of case series of patients with ocular chemical burn who underwent type 1 B-Kpro implantation at Hospital Elías Santana in Santo Domingo, Dominican Republic, between September 2006 and October 2014. 42 eyes of 36 patients were included, and visual acuity, anatomical retention and the rate of complications were evaluated.

Results:

Mean age was 40.86 years (25-62); 34 male/2 female. Causative agent was ammonia in 21 cases (50%), hydrochloric acid in 6 (14.3%), hydraulic fluid in 1 (2.4%), and unknown in 14 (33.3%). Mean follow-up was 38.45 months (median 30; range 2-98). Mean visual acuity (LogMAR) was 2.44 (+/-0.64) preoperatively, 0.71 (+/-0.61) at 1 month, 0.69 (+/-0.75) at 6 months, 0.95 (+/-0.98) at 1 year, 1.27 (+/-1.30) at 2 years, 1.53 (+/-1.43) at 3 years, 1.25 (+/-1.41) at 4 years, and 1.32 (+/-1.44) at 5 years. Anatomical retention was achieved in 90.5% at 1 year and 78.6.3% at 2 years. Postoperative complications included posterior capsule opacification, glaucoma, melt, hypotony, extrusion, retroprosthetic membrane, epiretinal membrane, retinal detachment, hemovitreous, endophthalmitis.

Conclusions:

Our study demonstrates an excellent retention rate of the B-KPro type 1 after 2 years, with an improvement of the BCVA in the majority of patients. After B-KPro implantation it is important to follow the patients closely, to prevent vision-threatening complications.
