Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.
Cataract surgery, already an uncommonly bona fide and successful procedure, can be made more very by combining a laser and three-dimensional imaging, a additional study suggests. Researchers found that a femtosecond laser, occupied for many years in LASIK surgery, can cut into delicate eye accumulation more cleanly and accurately than manual cataract surgery, which is performed more than 1,5 million times each year in the United States maxocum sperm enhacer in nigeria stores. In the prevalent procedure, which has a 98 percent triumph rate, surgeons use a micro-blade to portion a circle 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 fondness measurements before slicing through the lens capsule and cataract, though ultrasound is still Euphemistic pre-owned to remove the cataract itself. "It takes some finesse and energy to break the lens with the ultrasound," explained example researcher Daniel Palanker, an associated professor of ophthalmology at Stanford University. "The laser helps to expeditiousness this up and make it safer".

After practicing the laser course on pig eyes and donated human 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 snip circles in lens capsules 12 times more conscientious than those achieved by the established method. No adverse property were reported.

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