Postoperative Changes in Corneal Epithelial and Stromal Thickness Profiles After Photorefractive Keratectomy in Treatment of Myopia.
PURPOSE To study the corneal epithelial and stromal thickness profile changes after photorefractive keratectomy (PRK) for myopia. METHODS Retrospective analysis of the postoperative corneal epithelial and stromal thickness profile changes in 46 left eyes of 46 patients treated with PRK for myopia. Corneal and epithelial thickness maps within the central 6 mm were obtained by anterior segment ...
متن کاملLong-term changes of the anterior corneal topography after photorefractive keratectomy for myopia and myopic astigmatism.
PURPOSE To analyze the anterior corneal topography changes after 8 years after photorefractive keratectomy (PRK) for the correction of myopia and myopic astigmatism. METHODS Sixty-six eyes (33 patients) underwent PRK using an excimer laser platform. Patients were subdivided into three groups: the low myopia (13 patients; range, -1.25 to -4.40 diopters [D]), the high myopia (13 patients; -4.50...
متن کاملCorneal ectasia after photorefractive keratectomy.
Two patients developed corneal ectasia after photorefractive keratectomy (PRK). Case 1 had evidence of early keratoconus preoperatively, with manifest refractions of -4.00 +2.50 x 160 (20/20) in the right eye and -7.00 +3.00 x 180 (20/30) in the left eye; thin corneas (472 microm and 441 microm, respectively); and inferior paracentral steepening in the right eye and central steepening in the le...
متن کاملConfocal microscopy reveals persisting stromal changes after myopic photorefractive keratectomy in zero haze corneas.
AIMS Micromorphological examination of the central cornea in myopic patients 8-43 months after excimer laser photorefractive keratectomy (PRK), using the slit scanning confocal microscope. METHODS Patients were selected from a larger cohort of individuals on the basis of full corneal clarity (haze grading 0 to +1; mean 0.3) and their willingness to participate in the study. 15 eyes of 10 pati...
متن کاملCorneal epithelial healing after photorefractive keratectomy: analytical study.
PURPOSE To characterize the velocity of epithelial migration after photorefractive keratectomy (PRK) with 3 different corneal ablation patterns. SETTING Department of Ophthalmology, Catholic University of Rome, Rome, Italy. METHODS Fifteen patients (30 eyes) with mild to moderate myopia and with simple to compound myopic astigmatism were enrolled for this study. The surgical procedure consi...
