Photorefractive keratectomy in the management of postradial keratotomy hyperopia and astigmatism
BACKGROUND The aim of this study is to evaluate the results of photorefractive keratectomy (PRK) in the management of postoperative hyperopia and astigmatism in patients with history of radial keratotomy (RK). MATERIALS AND METHODS This prospective nonrandomized noncomparative interventional case series enrolled consecutive eyes treated with PRK after RK. In cases, in which (1) wavefront (WF)...
متن کاملPhotorefractive keratectomy for hyperopia after radial keratotomy.
BACKGROUND Progressive hyperopia is a common complication following radial keratotomy. METHODS Ten eyes of ten consecutive patients with hyperopia after radial keratotomy between +1.75 and +4.00 diopters (D) were treated with the hyperopia module of the Nidek Model EC-5000 excimer laser. The mean preoperative uncorrected visual acuity was 0.38 (20/60+). RESULTS After excimer laser photorefr...
متن کاملExcimer laser photorefractive keratectomy for hyperopia.
BACKGROUND AND OBJECTIVE Photorefractive keratectomy (PRK) has been extensively evaluated for the correction of myopia. This study was undertaken to assess the safety, efficacy, and reliability of PRK in the correction of hyperopia. PATIENTS AND METHODS There were 28 eyes with refractions of +1 to +7.75 D treated for hyperopia with the Chiron Technolas 217-C excimer laser. Thorough visual ass...
متن کاملArcuate transverse keratotomy remains a useful adjunct to correct astigmatism in conjunction with photorefractive keratectomy.
PURPOSE To retrospectively evaluate the effectiveness of paired, arcuate transverse keratotomy (Arc-T) performed prior to or after photorefractive keratectomy (PRK) to correct low to moderate amounts of natural or laser-induced astigmatism. METHODS Spherical PRK was performed in 730 eyes for myopia of -1.00 to -7.00 D. PRK with arcuate transverse keratotomy was performed in 150 of these eyes;...

PURPOSE To describe a topographically guided photorefractive keratectomy technique for the management of secondary hyperopia following radial keratectomy. METHODS A retrospective study was carried out in patients where a topographically guided photorefractive keratectomy technique was performed for the management of secondary hyperopia following radial keratectomy. The patients had preoperati...
