Epipolis-laser in situ keratomileusis versus photorefractive keratectomy for the correction of myopia: a meta-analysis

摘要: It is unclear whether epipolis-laser in situ keratomileusis (Epi-LASIK) has any significant advantage over photorefractive keratectomy (PRK) for correcting myopia. We undertook this meta-analysis of randomized controlled trials and cohort studies to examine possible differences efficacy, predictability, side effects between Epi-LASIK PRK A system literature review was conducted the PubMed, Cochrane Library EMBASE. The statistical analysis performed by RevMan 5.0 software. results included efficacy outcomes (percentage eyes with 20/20 uncorrected visual acuity post-treatment), predictability (proportion within ±0.5 D target refraction), epithelial healing time, incidence haze pain scores after surgery. There are seven articles total 987 suitable meta-analysis. no significance PRK, risk ratio (RR) 1.03, 95% confidence interval (CI) [0.92, 1.16], p = 0.18; respect odds 1.43, CI [0.85, 2.40], 0.56 there either. cell layer time showed these two techniques although more pains can be found than at early-stage post-operation. According above analysis, good as PRK. In addition, both have low haze.
