PURPOSE To perform a masked study to determine whether resolvin E1 (RvE1), a lipid-derived immunomodulator, could regulate the development of corneal haze and opacity-related myofibroblasts after opacity-generating high correction photorefractive keratectomy (PRK) in rabbits. METHODS Three groups of eight rabbits each were included in the study. Nine diopter (D) PRK for myopia was performed i...

background: silicon hydrogel bandage contact lenses are used to enhance epithelial healing, control surface-generated pain, and prevent epithelial erosions after refractive surgery. considering the importance of faster reepithelialization in preventing complications of photorefractive keratectomy (prk) and the fact that the features and specifications of these commercially-available lenses are ...

purpose: to compare tear secretion values following lasik (laser in situ keratomileusis) and photorefractive keratectomy (prk). methods: patients referred to aban eye clinic (isfahan, iran) for refractive surgery were randomly assigned to lasik or prk. exclusion criteria were contraindications for refractive surgery, usage of topical ocular drugs, dry eye and reoperation. schirmer test was perf...

PURPOSE To evaluate the results of combined aspheric wavefront-guided transepithelial excimer laser photorefractive keratectomy (PRK) and phototherapeutic keratectomy (PTK) to correct aberrations and refractive errors after radial keratotomy (RK) or keratoplasty. SETTING Sekal Rovigo Microsurgery Centre, Rovigo, Italy. METHODS This retrospective noncomparative consecutive case series compri...

to compare the refractive and visual outcomes and higher order aberrations in patients with low to moderate myopia who underwent customized photorefractive keratectomy (prk) or  femtosecond laser in situ keratomileusis (femto-lasik) this study performed this research includes data of 120 consecutive eyes of 60 patients with myopia between -3.00 d and -7.00 d with or without astigmatism in two s...

PURPOSE We investigated the keratocyte response and stromal remodeling after corneal incision and photorefractive keratectomy to understand the histophysiological and immunohistochemical differences between these two types of surgery. METHODS Corneal incision or photorefractive keratectomy was performed in rabbits or rats. Then we chronologically observed the histological changes and the chan...

PURPOSE To report the outcomes of topography-guided photorefractive keratectomy (PRK) for the treatment of myopia with or without astigmatism using the customized aspheric transition zone (CATz) ablation algorithm. METHODS In this study, 335 eyes underwent PRK using the NIDEK Advanced Vision Excimer laser platform (NAVEX). Mean preoperative manifest refraction spherical equivalent was -4.42+/...

Purpose: To investigate the application of mitomycin-C 0.02% (MMC) in the photorefractive keratectomy (PRK) procedure in correcting regressed myopia Methods: Eighteen eyes of 11 patients with a spherical equivalent (SE) of less than -5 diopters (D) who had undergone laser in situ keratomileusis (LASIK) more than 2 years before were operated on. At the end of the PRK procedure, MMC was applied o...

PURPOSE To compare the outcomes and complications of alcohol-assisted versus mechanical corneal epithelial debridement for photorefractive keratectomy (PRK). METHODS This randomized controlled trial included 1,250 eyes of 625 patients undergoing PRK for correction of myopia and myopic astigmatism. Each patient was randomly assigned to alcohol-assisted or mechanical epithelial removal. RESUL...
