| Abstract;Purpose: To evaluate the efficacy of photorefractive keratectomy(PRK) with a scanning type excimer laser MEL-60(AESCLUP-MEDITEC, Co). Subjects and Method: We performed PRK on 102 eyes of 62 myopic patients whose refraction ranged from -3.00 to -12.50D(mean, -6.47D) and examined the clinical results of postoperative refraction and complications. Results: At 12,18, and 24 months after the operation, the mean refraction was -1.57.+-.1.25D, -1.63.+-.1.51D, and -1.73.+-.1.47D. At 12 months after the operation, 36 eyes(46.2%) were within .+-.0.5D of intended correction, 61 eyes(78.3%) within .+-.1.0D, and 76 eyes(97.4%) within .+-.2.0D. Twenty-four months after the operation, 12 eyes(37.5%) were within .+-.0.5D, 18 eyes(56.3%) within .+-.1.0D and 29 eyes(90.6%) within .+-.2.0D. The complications were as follows: keratitis filamentosa was observed in 10 eyes(10.5%), decrease of contrast sensitivity in 7 eyes(7.4%), subepithelial corneal haze in 4 eyes(4.2%), steroid-induced glaucoma was 2 eyes(2.1%), increase of astigmatism in 2 eyes(2.1%), decrease of best corrected visual acuity in 2 eyes(2.1%), and corneal ulcer in 1 eyes(1.1%). Conclusion: PRK with a scanning type excimer laser MEL-60 was effective to reduce refractive error in low and mild myopia, but there were some complications, so that a long, careful follow-up seems necessary.
