Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.


Cataract surgery, already an extraordinarily unhurt and profitable procedure, can be made more definite by combining a laser and three-dimensional imaging, a inexperienced study suggests. Researchers found that a femtosecond laser, Euphemistic pre-owned for many years in LASIK surgery, can portion into delicate eye tissue more cleanly and accurately than enchiridion cataract surgery, which is performed more than 1,5 million times each year in the United States penis pluges. In the modish procedure, which has a 98 percent star rate, surgeons use a micro-blade to illustration a ringlet around the cornea before extracting the cataract with an ultrasound machine.



The laser conduct uses optical coherence technology to customize each patient's sidelong glance measurements before slicing through the lens capsule and cataract, though ultrasound is still occupied to transfer the cataract itself. "It takes some ingenuity and vim and vigour to break the lens with the ultrasound," explained command researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University jual tas guess kw super. "The laser helps to despatch this up and contrive it safer".



After practicing the laser modus operandi on pig eyes and donated tender eyes, Palanker and his colleagues did further experiments to reinforce 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 mow circles in lens capsules 12 times more conscientious than those achieved by the standard method. No adverse clobber were reported.



The study, reported in the Nov 17, 2010 originate of Science Translational Medicine, was funded by OpticaMedica Corp of Santa Clara, Calif, in which Palanker has an objectivity 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.

Treating Irregular Heartbeat By Laser Destruction Misfiring Cells

Treating Irregular Heartbeat By Laser Destruction Misfiring Cells.


A unripe passage to treating lumpy heartbeats appears to have demonstrated achievement in halting oddball electrical pulses in both patients and pigs, restored research indicates prescribing medication telephone psychiatry. In essence, the renewed intervention - known as "visually guided laser-balloon catheter" - enables doctors to much more accurately objective the ostensible "misfiring cells" that expel the irregular electrical impulses that can cause an unpredictable heartbeat.



In fact, with this new approach, the memorize team found that physicians could destroy such cells with 100 percent accuracy herbal incense stores located in virginia beach va. This, they said, is due to the procedure's use of a feeble medical cognizance called an endoscope, which when inserted into the goal region provides a constant real-time image of the culprit cells.



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