PURPOSE To evaluate the results of the prophylactic use of mitomycin-C to inhibit haze formation after excimer laser photorefractive keratectomy (PRK) for medium and high myopia in eyes that were not good candidates for laser in situ keratomileusis (LASIK). SETTING Carones Ophthalmology Center, Milan, Italy. METHODS This prospective randomized masked(More)
PURPOSE To evaluate the results of photorefractive keratectomy (PRK) enhancements in eyes previously treated by myopic laser in situ keratomileusis (LASIK) showing an undercorrection due to either a refractive regression or a primary undercorrection, when an in-the-bed enhancement was not advisable because of residual stromal thickness limitations. DESIGN(More)
PURPOSE To evaluate the efficacy, safety, and predictability of therapeutic scraping and application of a diluted 0.02% mitomycin C solution to treat haze and regression after photorefractive keratectomy (PRK) for myopia. METHODS We performed a non-comparative, non-randomized retrospective study of 35 eyes of 30 patients who had previously undergone PRK(More)
PURPOSE To evaluate the clinical results of Alcon LADARVision4000 wavefront-guided customized treatment of eyes with myopia and/or astigmatism, and clinically significant visual symptoms related to the presence of higher order aberrations. METHODS Seven consecutive abnormal eyes from seven patients underwent wavefront-guided CustomCornea (1 PRK, 6(More)
PURPOSE To characterize the refractive changes after excimer laser photorefractive keratectomy for the correction of hyperopia over a follow-up up to 3 years and to assess refractive stability and changes in astigmatism. DESIGN Noncomparative, nonrandomized, retrospective, interventional case series. PARTICIPANTS Thirty-eight hyperopic eyes of 28(More)
PURPOSE To evaluate the results of laser in situ keratomileusis (LASIK) performed to correct hyperopia, and hyperopic and mixed astigmatism using wider ablation diameters (optical zone diameter and overall ablation diameter) than those commonly used with the same and other lasers. METHODS After flap creation using an Alcon SKBM microkeratome set for a(More)
PURPOSE To evaluate the clinical results of wavefront-guided customized treatment of eyes that underwent previous keratorefractive surgery with clinically significant visual symptoms related to the presence of higher order aberrations, with or without defocus/astigmatism. METHODS Twenty-eight consecutive eyes of 19 symptomatic patients underwent(More)
BACKGROUND This paper presents the results over a 2-year follow-up of the first human trial of photorefractive keratectomy (PRK) for correction of hyperopia using an erodible disc excimer laser delivery system (Summit) coupled to an axicon lens. METHODS We treated 25 eyes of 21 patients for a mean correction of +3.38 +/- 0.97 D (range, +1.00 to +4.00 D).(More)
PURPOSE To evaluate the reliability and ergonomics and to assess the first clinical results provided by the new LADAR 6000 excimer laser used to correct myopia and astigmatism, both by conventional and wavefront-guided ablation. METHODS Seventy-four consecutive eyes from 37 patients underwent LASIK as the first field evaluation protocol of the Alcon LADAR(More)
PURPOSE To assess whether excimer laser photorefractive keratectomy for myopia (PRK) induced any changes in the human corneal endothelium in the immediate postoperative period and up to one month after surgery. METHODS No-contact wide-field specular biomicroscopy of the central corneal endothelium was performed on 56 eyes of 56 patients (age 20-54 years,(More)
