Outcomes of photorefractive keratectomy in patients with atypical topography
Background Photorefractive keratectomy (PRK) is at risk of serious complications such as corneal ectasia, which can reduce corrected distance visual acuity. The rate of complications of PRK is higher in patients with atypical topography. Objective To determine the outcomes of photorefractive keratectomy in patients with atypical topography. Methods This cross-sectional study was done in 201...
متن کاملFeasibility of intraoperative corneal topography monitoring during photorefractive keratectomy.
PURPOSE We propose a feasibility study of new corneal topography technology with the aim of monitoring intraoperative corneal topography during excimer laser photorefractive keratectomy. The PAR system measures corneal topography with single grid projection and triangulation but requires fluorescent fluid to be deposited on the corneal surface for shape extraction. We propose and demonstrate a ...
متن کاملOutcomes of Photorefractive Keratectomy with Intraoperative Mitomycin-C
PURPOSE To report the efficacy, safety, predictability and complications of photorefractive keratectomy (PRK) with intraoperative application of mitomycin-C (MMC). METHODS This historical cohort study was performed on 1,250 eyes of 625 patients who underwent PRK using the Technolas 217 excimer laser machine by a single surgeon with intraoperative use of MMC 0.02% up to 2 minutes, depending on...
متن کاملPhotorefractive Keratectomy in Keratoconus
PURPOSE To assess the efficacy and safety of topography-guided photorefractive keratectomy (PRK) for keratoconus and to estimate the subsequent risk of progression. METHODS This is a retrospective follow-up study. Between 1998 and 2013, 28 eyes of 23 patients (age 17-60) with grade 1-3 keratoconus received topography-guided PRK. Corrected-distance visual acuity (CDVA), keratometry, pachymetry...
