OBJECTIVE To determine the incidence and severity of complications from laser in situ keratomileusis (LASIK) for the correction of myopia by experienced and inexperienced surgeons. DESIGN Prospective, observational clinical study. PARTICIPANTS Fourteen surgeons and 1062 eyes of 574 myopic patients who desired surgical correction of myopia ranging from(More)
Excimer laser photorefractive keratectomy and excimer laser in situ keratomileusis are relatively new treatment modalities that can be used to correct refractive errors of the eye. They are most commonly used to correct myopia (nearsightedness) but can also be used to correct hyperopia (farsightedness) and astigmatism. The excimer laser alters the(More)
OBJECTIVE This study aimed to determine whether there is a true difference in predictability between single-zone and multizone laser in situ keratomileusis (LASIK) for the correction of low myopia or whether any difference in predictability is because of a need for separate clinical nomograms for the two treatments. DESIGN A prospective, randomized,(More)
The use of magnesium sulfate infusion for the management of cardiac dysrhythmia has recently gained popularity. Magnesium sulfate has been advocated for the management of torsade de pointes and other ventricular dysrhythmias. We report the case of a 38-year-old firefighter with atrial tachycardia that was treated unsuccessfully according to Advanced Cardiac(More)
PURPOSE To review the major advances in the field of refractive surgery occurring over the past 25 years. METHODS Literature review. RESULTS The major developments in refractive surgery over the past 25 years are reviewed. CONCLUSIONS The past 25 years have witnessed great changes in refractive surgery. As a result of advancements in technology,(More)
PURPOSE To construct a quantitative model relating refractive results to laser settings and other factors. METHODS A prospective clinical trial was performed, including 14 surgeons and 523 eyes of 278 patients who desired correction of myopia from -1.00 to -16.00 D (mean, -6.20 D) and astigmatism up to 6.00 D (mean, 1.10 D). Myopia and astigmatism were(More)
OBJECTIVE To study the safety and efficacy of simultaneous bilateral laser in situ keratomileusis (LASIK). DESIGN Prospective randomized clinical trial. PARTICIPANTS Fourteen surgeons and 714 consecutive eyes of 357 patients who desired surgical correction of myopia ranging from -2.00 to -22.50 diopters. INTERVENTION Patients were randomized to(More)
Laser in-situ keratomileusis is an increasingly popular technique for the correction of refractive errors that was initially described by Pallikaris in 1990. It involves the excimer laser ablation of corneal stroma beneath a hinged corneal flap that is created with a microkeratome. The purpose of this chapter is to report the LASIK surgical technique that(More)
PURPOSE To report an unusual epibulbar inflammatory process in a patient with human immunodeficiency virus (HIV). METHODS Case report. A 32-year-old man developed fleshy epibulbar nodules on his right conjunctiva and cornea after being treated for conjunctivitis. A biopsy of the lesions was done, and the specimen was processed for histopathologic(More)
OBJECTIVE To assess the safety and effectiveness of the Summit Autonomous LADARVision active tracking narrow beam excimer laser system for laser in situ keratomileusis (LASIK) correction of myopia and astigmatism. DESIGN A multicenter, prospective noncomparative case series. PARTICIPANTS This cohort consisted of 177 eyes corrected for spherical myopia(More)
