The epithelial flap for photorefractive keratectomy.
BACKGROUND/AIMS Epithelial debridement for photorefractive keratectomy (PRK) is associated with pain, slower visual recovery, and may be aetiological in haze production. The aim of this study was to assess the clinical results of a new technique involving raising and replacing of an epithelial flap in photorefractive keratectomy. METHODS A prospective, non-randomised, comparative, paired eye ...
متن کاملCorneal epithelial recovery following photorefractive keratectomy.
AIMS To further understand the morphological and functional recovery of corneal epithelium following excimer laser photorefractive keratectomy (PRK). METHODS The right eyes (group 1) of 15 male, New Zealand white rabbits weighing 2-3 kg underwent PRK. The left eye of each rabbit (group 2) underwent simple mechanical de-epithelialisation and were examined as treated controls. Both eyes of anot...
متن کاملPhotorefractive keratectomy after late traumatic LASIK flap loss.
PURPOSE To present a case of photorefractive keratectomy (PRK) after late traumatic LASIK flap loss. METHODS The initial LASIK procedure was performed in 2003 with a Moria M2 microkeratome and NIDEK EC-5000 excimer laser using a 5.0/9.0-mm aspheric ablation pattern, resulting in 20/20(+) uncorrected distance visual acuity (UDVA) and plano refraction. Traumatic flap loss of the right eye occur...
متن کاملRole of epithelial hyperplasia in regression following photorefractive keratectomy.
AIM To determine the relation between epithelial hyperplasia and regression of effect after photorefractive keratectomy (PRK). METHODS Seventy unilaterally treated patients with PRK were examined. All eyes had been treated with the Summit excimer laser 27 (SD 7) months previously with zone diameters of 4.1 to 5.0 mm. The untreated fellow eyes served as controls. Epithelial thickness was measu...
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...
