comparison of two techniques: photorefractive keratectomy versus laser in situ keratomileusis for low myopia
purpose: to determine the efficacy, safety, and stability of these techniques and some factors affecting refractive and visual outcomes in treated patients. methods: 236 lasik-treated eyes (122 patients) and 218 prk-treated eyes (112 patients) with myopia and myopic-astigmatism between -1.25 and -4 diopters (d) underwent refractive surgery over an 11 month period by a single surgeon. patients w...
متن کاملComparison of two procedures: photorefractive keratectomy versus laser in situ keratomileusis for low to moderate myopia.
PURPOSE A prospective study was conducted to compare the effectiveness, safety, and stability of photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) for correction of low to moderate myopia. METHODS Forty-five patients with a manifest refraction (PRK, -4.54 +/- 0.80; LASIK, -4.82 +/- 1.10) from -1.50 to -6.00 diopters (D) were treated and followed-up for 6 months. In ea...
متن کاملPhotorefractive Keratectomy for Residual Myopia after Myopic Laser In Situ Keratomileusis
Purpose. To evaluate the safety, efficacy, and predictability of photorefractive keratectomy (PRK) on the corneal flap for correction of residual myopia following myopic laser in situ keratomileusis (LASIK). Patients and Methods. A retrospective study on eyes retreated by PRK on the corneal flap for residual myopia after LASIK. All eyes had no enough stroma after LASIK sufficient for LASIK enha...

متن کاملEvaluation of the effectiveness of laser in situ keratomileusis and photorefractive keratectomy for myopia: a meta-analysis.
OBJECTIVE To evaluate the effectiveness of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) for correcting myopia. METHODS Study selection, data extraction, and quality assessment were performed by two of authors independently. Summary odds ratios and 95% confidence intervals were calculated by DerSimonian & Laird random-effects model and Mantel-Haenszel (fixed-effec...
