1113 Clinical results of photorefractive keratectomy by excimer laser treatment
Purpose: To evaluate. long term efficacy, safety and stability of PRK for low and moderate myopia. Methods: 110 patients were treated for myopia up to 6D with the Summit Excimed excimer laser. The optical zone was 5mm in all cases. Manifest t&action. refraction under cycloplegla, comenl haze and comeal topography werc studied at D15, 1. 3, 6. 12. and 24 months after the surgery. Results: 110 pa...
متن کاملEye dominance in excimer laser photorefractive keratectomy.
human species and is relevant in clinical practice—to excimer laser photorefractive keratectomy (PRK) in particular. Due to the complexity of the underlying physiological mechanisms, there is no single definition that applies to all aspects of ocular dominance. Nevertheless, a clinically useful definition would be, “The dominant eye is the eye that is preferred in monocular viewing or in pointi...
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 کاملExcimer laser photorefractive keratectomy for hyperopia.
BACKGROUND AND OBJECTIVE Photorefractive keratectomy (PRK) has been extensively evaluated for the correction of myopia. This study was undertaken to assess the safety, efficacy, and reliability of PRK in the correction of hyperopia. PATIENTS AND METHODS There were 28 eyes with refractions of +1 to +7.75 D treated for hyperopia with the Chiron Technolas 217-C excimer laser. Thorough visual ass...
متن کاملPlasminogen activator activity in tears after excimer laser photorefractive keratectomy.
PURPOSE To quantify changes of plasminogen activator activity in tear fluid during corneal re-epithelialization after excimer laser photorefractive keratectomy (PRK). METHODS Tear samples were collected with glass capillaries from 77 eyes of 42 patients immediately before and immediately after PRK treatment and on postoperative days 3 and 5. In 20 patients, the contralateral eye was similarly...
