INTRODUCTION Refractive surgery, specifically photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK), is becoming more accepted in the military environment. Determination of the impact on visual performance in the more demanding aviation environment was the impetus for this study. METHODS A prospective evaluation of 20 Black Hawk pilots pre-surgically and at 1 wk, 1 mo, an...

Purpose. To report an unusual case of severe bilateral fungal keratitis following laser in situ keratomileusis (LASIK). Method. A 48-year-old man developed bilateral diffuse corneal infiltration two weeks after LASIK. The corneal scrapings revealed fungal filaments but cultures were negative. Results. The corneal ulceration was improved on the left eye whereas spontaneous perforation occurred a...

PURPOSE We report a case of a patient with a history of glomerulonephropathy, not disclosed prior to laser in situ keratomileusis (LASIK), who developed severe postoperative peripheral ulcerative keratitis (PUK) soon after surgery. METHOD Case report. RESULTS Within a week of surgery, the patient, who had no blepharitis or ocular surface disease, also developed diffuse lamellar keratitis (D...

AIMS To quantitatively evaluate the changes in corneal irregular astigmatism after laser in situ keratomileusis (LASIK) in relation to the amount of laser ablation. METHODS In 189 eyes of 116 patients undergoing LASIK for myopia, corneal topography was obtained before and 1 month after surgery. Using Fourier harmonic analysis of the topography data, corneal irregular astigmatism (asymmetry an...

INTRODUCTION Refractive ophthalmic surgery allows refractive errors to be corrected permanently in a safe, effective, and reliable way with few complications. METHODS Selective literature review with special reference to the guidelines of the German Commission for Refractive Surgery. RESULTS With a total of almost 18 million treatments performed to date, laser in-situ keratomileusis (LASIK)...

Ams: To describe the characteristics and surgical outcomes of full thickness macular hole surgery after laser assisted in situ keratomileusis (LASIK) for the correction of myopia. Methods: 13 patients (14 eyes) who developed a macular hole after bilateral LASIK for the correction of myopia participated in the study. Results: Macular hole formed 1–83 months after LASIK (mean 13 months). 11 out o...

PURPOSE To relate the change of ocular aberrations with the change of visual performance produced by standard laser in situ keratomileusis (LASIK) for myopia. METHODS Aberrations and visual performance were measured before and after surgery in 22 eyes. Total aberrations were measured using a laser ray tracing technique. Corneal aberrations were obtained using a commercial videokeratoscope and...

PURPOSE To analyze the early results of a new device measuring ocular biomechanics after corneal refractive surgery. PATIENTS AND METHODS Thirty nine refractive surgery patients were enrolled in the study (age: 32.6±9.9 years). Laser in situ keratomileusis (LASIK) was performed on 52 eyes of 26 patients and photorefractive keratectomy (PRK) was done on 26 eyes of 13 patients. Ten device-speci...

purpose: to evaluate the role of prophylactic topical steroids in the prevention of dlk after lasik. methods: in a randomized double blind clinical trial, 101 lasik candidates aged 18 to 55 years were enrolled. myopia ranged from -2 to -12 diopters and was stable for at least one year. no patient had any ocular or systemic contraindication for lasik. from one day before surgery, topical betamet...
