Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.


Cataract surgery, already an damned tried and true and winning procedure, can be made more critical by combining a laser and three-dimensional imaging, a revitalized study suggests. Researchers found that a femtosecond laser, occupied for many years in LASIK surgery, can cut dow a fell into delicate eye tissue more cleanly and accurately than guide cataract surgery, which is performed more than 1,5 million times each year in the United States buspar purchase. In the trend procedure, which has a 98 percent good rate, surgeons use a micro-blade to separated a around around the cornea before extracting the cataract with an ultrasound machine.



The laser custom uses optical coherence technology to customize each patient's visual acuity measurements before slicing through the lens capsule and cataract, though ultrasound is still Euphemistic pre-owned to take away the cataract itself. "It takes some adeptness and dynamism to break the lens with the ultrasound," explained conduct researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University vazox penis enlargement pills. "The laser helps to skedaddle this up and affirm it safer".



After practicing the laser plan on pig eyes and donated sensitive eyes, Palanker and his colleagues did further experiments to clinch that the high-powered, rapid-pulse laser would not cause retinal damage. Actual surgeries later performed on 50 patients between the ages of 55 and 80 showed that the laser jibe circles in lens capsules 12 times more faithful than those achieved by the ritual method. No adverse clobber were reported.



The study, reported in the Nov 17, 2010 emanate of Science Translational Medicine, was funded by OpticaMedica Corp of Santa Clara, Calif, in which Palanker has an tolerance stake. The results are being reviewed by the US Food and Drug Administration, while the laser technology, which is being developed by several exclusive companies, is expected to be released worldwide in 2011.
