Photorefractive keratectomy for patients with preoperative low Schirmer test value
PURPOSE To compare dry eye signs and symptoms between patients with preoperative low and normal Schirmer test after Photorefractive keratectomy (PRK). METHODS In this prospective, nonrandomized, comparative case series, 76 eyes of 76 patients were preoperatively categorized into two groups according to selected criteria for characterization of tear film status: the low Schirmer test value (ST...

PURPOSE To compare the effectiveness, safety and stability of the results of transepithelial photorefractive keratectomy (tPRK) with conventional photorefractive keratectomy (PRK) for low to moderate myopia. METHODS In this prospective non-randomized case-control study, patients with low to moderate myopia were assigned to the tPRK group (cases) or the PRK group (controls). In the tPRK group,...

PURPOSE To analyse visual, refractive and topographic outcomes of combining transepithelial photorefractive keratectomy (tPRK) with simultaneous corneal crosslinking for the visual rehabilitation of contact lens intolerant keratoconus patients. METHODS Patients with topographically significant keratoconus, limited corrected vision and intolerant of contact lenses were prospectively recruited,...
متن کاملPhotorefractive keratectomy for myopia and photoastigmatic keratectomy for astigmatism.
BACKGROUND We conducted a clinical trial to evaluate the efficacy and safety of excimer laser photorefractive keratectomy (PRK) and photoastigmatic refractive keratectomy (PARK) using the Nidek EC-5000 excimer laser. METHODS A total of 67 eyes from 47 patients whose average age was 35 years were enrolled in the study. The mean spherical equivalent of the manifest refraction before surgery was...
متن کاملOutcomes 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...
