Laser-assisted subepithelial keratectomy (LASEK) without alcohol versus photorefractive keratectomy (PRK).
PURPOSE To evaluate epithelial healing and visual outcome after laser-assisted subepithelial keratectomy (LASEK) without alcohol de-epithelialization and to compare this technique to photorefractive keratectomy (PRK) in myopia. METHODS In a series of 1953 patients undergoing bilateral myopic PRK, an epithelial flap could be obtained by manual de-epithelialization in the left eye of 56 patient...
متن کاملExcimer laser photorefractive keratectomy for high myopia.
One hundred and thirty-three eyes of 103 patients had photorefractive keratectomy with a slit scan mode excimer laser for myopia ranging from -6.00 to -22.00 diopters (D). The epithelium was removed with 20% ethanol, and the ablation was done with a tapered profile surrounding the optical zone. Patients were divided into two groups based on preoperative myopia: Group A, -6.00 D to -12.00 D (88 ...
متن کاملlaser in situ keratomileusis versus laser assisted subepithelial keratectomy for the correction of low to moderate myopia and astigmatism
purpose : to compare the visual and refractive outcomes of laser in situ keratomileusis (lasik) versus laser assisted subepithelial keratectomy (lasek) in the treatment of low to moderate myopia and astigmatism methods : a retrospective comparative case series study comprised 2,474 eyes of patients with manifest refraction spherical component lower than -5.00 diopters (d) and cylinder component...
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 کاملVisual performance after excimer laser photorefractive keratectomy for high myopia
PURPOSE To evaluate the efficacy, safety, predictability, and visual performance of excimer laser photorefractive keratectomy (PRK) for myopia greater than -8 diopters (D). METHODS Fifty-four patients (104 eyes) with myopia from -8D to -13D and cylinder up to -4D received surface ablation technique with the Allegretto wave version 1009-1 excimer laser to correct their refractive error. The pa...
