Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.


Cataract surgery, already an hellishly allowable and prosperous procedure, can be made more unyielding by combining a laser and three-dimensional imaging, a renewed study suggests. Researchers found that a femtosecond laser, in use for many years in LASIK surgery, can incision into delicate eye tissue more cleanly and accurately than instructions cataract surgery, which is performed more than 1,5 million times each year in the United States houston black seed oil. In the fashionable procedure, which has a 98 percent prosperity rate, surgeons use a micro-blade to thin a disc around the cornea before extracting the cataract with an ultrasound machine.



The laser standard operating procedure uses optical coherence technology to customize each patient's perspicacity measurements before slicing through the lens capsule and cataract, though ultrasound is still Euphemistic pre-owned to unfasten the cataract itself. "It takes some aptitude and power to break the lens with the ultrasound," explained convince researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University . "The laser helps to skedaddle this up and organize it safer".



After practicing the laser scheme on pig eyes and donated accommodating eyes, Palanker and his colleagues did further experiments to accredit 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 avoid circles in lens capsules 12 times more accurate than those achieved by the customary method. No adverse goods were reported.



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