Photorefractive keratectomy in african american including thoe with known dermatologic keloid formation Original Reearch Article

PURPOE: To report the outcome of photorefractive keratectomy in African American, including thoe with a known hitory of dermatologic keloid formation. METHOD: A retropective analyi of African American patient who had photorefractive keratectomy at either of our intitution wa undertaken to identify all patient who were at leat 3 month tatu-pot refractive urgery. The preence or abence of a hitory of keloid formation, a well a preoperative and potoperative meaurement of uncorrected viual acuity, bet-corrected viual acuity, manifet refraction, and the preence and magnitude of any potoperative corneal haze were analyzed. REULT: Twelve patient (19 eye) met the incluion criteria and three of thee patient (ix eye) had a hitory of keloid formation. Mean uncorrected viual acuity ± D for the entire tudy group improved from 20/369 ± 20/270 preoperatively to 20/19.4 ± 20/7.1 potoperatively (average follow-up, 13.8 month). All eye had potoperative uncorrected viual acuity of 20/40 or better; 14 (74%) achieved 20/20 or better. Mean bet pectacle corrected viual acuity went from 20/14.8 ± 20/2.8 preoperatively to 20/15.5 ± 20/3.2 potoperatively (not tatitically ignificant). Mean manifet pherical equivalent wa –4.9 ± 3.4 diopter preoperatively and +0.03 ± 0.55 diopter potoperatively. Eight eye (42%) had trace to 1+ corneal haze following photorefractive urgery. A comparion of potoperative uncorrected and bet-corrected viual acuitie of known keloid former with nonkeloid former revealed no ignificant tatitical difference. CONCLUION: African American may have excellent viual outcome following photorefractive keratectomy. Hitory of keloid formation doe not appear to have an advere effect on the outcome. Thee reult quetion whether known dermatologic keloid formation hould be a contraindication to photorefractive keratectomy.
