Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.


Cataract surgery, already an hellishly out of harm's way and wealthy procedure, can be made more prim by combining a laser and three-dimensional imaging, a immature study suggests. Researchers found that a femtosecond laser, worn for many years in LASIK surgery, can retrench into delicate eye tissue more cleanly and accurately than handbook cataract surgery, which is performed more than 1,5 million times each year in the United States vimax cook growth price. In the widely known procedure, which has a 98 percent name rate, surgeons use a micro-blade to abbreviated a coterie around the cornea before extracting the cataract with an ultrasound machine.



The laser routine uses optical coherence technology to customize each patient's discrimination measurements before slicing through the lens capsule and cataract, though ultrasound is still reach-me-down to rub the cataract itself. "It takes some knack and determination to break the lens with the ultrasound," explained govern researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University glutathione injection dubai. "The laser helps to abruptness this up and originate it safer".



After practicing the laser plan on pig eyes and donated humanitarian eyes, Palanker and his colleagues did further experiments to endorse 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 abbreviate circles in lens capsules 12 times more finical than those achieved by the old method. No adverse chattels were reported.



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

Treating Irregular Heartbeat By Laser Destruction Misfiring Cells

Treating Irregular Heartbeat By Laser Destruction Misfiring Cells.


A restored approximate to treating lopsided heartbeats appears to have demonstrated happy result in halting unconventional electrical pulses in both patients and pigs, rejuvenated research indicates rxlistplus.com. In essence, the untrodden intervention - known as "visually guided laser-balloon catheter" - enables doctors to much more accurately object the self-styled "misfiring cells" that out the irregular electrical impulses that can cause an discursive heartbeat.



In fact, with this new approach, the look team found that physicians could destroy such cells with 100 percent accuracy is single bottle nembutal enough. This, they said, is due to the procedure's use of a insignificant medical machination called an endoscope, which when inserted into the butt region provides a connected real-time image of the culprit cells.



The stock means for getting at misfiring cells relies on pre-intervention X-rays for a much less verbatim snapshot form of visual guidance. The findings are reported by scrutinize maker Dr Vivek Y Reddy, a ranking faculty member in medicine and cardiology at the Mount Sinai Medical Center in New York City, and colleagues in the May 26 online print run of Circulation: Arrhythmia and Electrophysiology.
