BACKGROUND A new technique, therapeutic alloplastic laser in situ keratomileusis to correct high myopia, is introduced. METHODS Therapeutic alloplastic laser in situ keratomileusis consists of neutral homoplastic epikeratoplasty combined with superficial keratectomy performed with an excimer laser and/or a microkeratome. Indications for the technique are: myopia over 20 diopters (D), eyes wit...

purpose: to report two cases of bilateral bacterial keratitis as a sight-threatening complication following photorefractive keratectomy (prk) patients and findings: the first case was a 45-year-old man referred due to bilateral ocular pain and purulent discharge two days after bilateral prk. based on his clinical picture, smear and cultures from both corneal ulcers were taken with a diagnosis o...

BACKGROUND It is unclear whether a laser epithelial keratomileusis (LASEK) has any significant advantage over a photorefractive keratectomy (PRK) for correcting myopia. We undertook this meta-analysis of randomized controlled trials to examine possible differences in efficacy, accuracy, safety and side-effects between two methods, LASEK and PRK, for correcting myopia. METHODS A systematic lit...

BACKGROUND In astigmatism clinical trials where more complex measurements are common, especially in nonrandomized small sized clinical trials, there is a demand for the development and application of newer statistical methods. METHODS The source data belonged to a project on astigmatism treatment. Data were used regarding a total of 296 eyes undergoing different astigmatism treatment modaliti...

PURPOSE To evaluate the efficacy and safety of diamond burr superficial keratectomy in the treatment of visually-significant anterior corneal lesions. METHODS A retrospective review of 23 eyes (23 patients). Pre- and postoperative visual acuities and refractions, slit-lamp biomicroscopic findings, and the incidence of recurrence of disease after keratectomy were studied. RESULTS Nineteen ey...

BACKGROUND/AIMS The biochemical basis for the development of subepithelial opacity of the cornea after excimer laser keratectomy has yet to be fully defined. The aim of this study was to evaluate the alterations of glycosaminoglycans (GAGs) after excimer laser keratectomy. METHODS Rabbit corneas were harvested on days 5, 10, 20, and 30 after excimer laser photoablation. The amount of main dis...
