In this paper, we examine the 193 nm excimer laser's efficacy and safety in treating myopic astigmatism. The VISX Twenty/Twenty excimer laser uses aperture elements to effect astigmatic photorefractive keratectomy. In 70 patients with six months follow-up, the average postoperative sphere was -0.14 and the average postoperative cylinder was -0.54.(More)
In a series of 50 patients undergoing secondary implantation of a Choyce-style anterior chamber lens, 43 (86%) had regained or improved their best corrected preoperative vision by the third postoperative month. Four eyes had intraoperative vitreous loss, one resulting in subchoroidal hemorrhage and another associated with CME. Of the four cases of CME,(More)
A novel alcohol-based antiseptic and a novel water-based antiseptic lotion, both with a synergistic combination of antimicrobial ingredients containing 0.2% benzethonium chloride, were evaluated using the standard time-kill method against 25 FDA-specified challenge microorganisms. The purpose of the testing was to determine whether a non-alcohol product(More)
Endothelial cell densities were measured following intracapsular cataract extraction and phacoemulsification in the same patients. Phacoemulsification caused 29 percent more endothelial cell loss than intracapsular cataract extraction (p less than .001). The degree of endothelial damage with phacoemulsification appeared to be age related and was minimal in(More)
A RELIABLE method and inexpensive instrumentation to measure and record simultaneous locomotion parameters and muscle firing patterns is needed for the clinical assessment and treatment of various neuromuscular diseases. Previously, systems developed to perform these tasks have only enabled the investigator to obtain a minimum set of data. In an experiment(More)
