Corneal cooling and rehydration during photorefractive keratectomy to reduce postoperative corneal haze.
PURPOSE An increase in corneal temperature has been implicated in subepithelial haze after surface photorefractive keratectomy. We aimed to determine if cooling the cornea by means of hydration between ablations and immediately after final surface ablation in PRK reduces haze. METHODS One hundred five eyes of 61 patients with myopia ranging from -6.00 to -9.75 D were included. One of the surg...
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 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 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...
متن کاملPostoperative 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 ...
