Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.
Cataract surgery, already an uncommonly all right and pre-eminent procedure, can be made more strict by combining a laser and three-dimensional imaging, a imaginative study suggests. Researchers found that a femtosecond laser, hand-me-down for many years in LASIK surgery, can sign 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 manual. In the up to date procedure, which has a 98 percent outcome rate, surgeons use a micro-blade to dig a gird around the cornea before extracting the cataract with an ultrasound machine.

The laser methodology uses optical coherence technology to customize each patient's look measurements before slicing through the lens capsule and cataract, though ultrasound is still in use to expunge the cataract itself. "It takes some faculty and zing to break the lens with the ultrasound," explained pattern researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University. "The laser helps to hasten this up and shape it safer".

After practicing the laser tradition on pig eyes and donated generous eyes, Palanker and his colleagues did further experiments to sanction 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 epitomize circles in lens capsules 12 times more literal than those achieved by the standard method. No adverse things 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 disinterest stake. The results are being reviewed by the US Food and Drug Administration, while the laser technology, which is being developed by several own companies, is expected to be released worldwide in 2011.

Cataract surgery, already an hellishly chest and well-fixed procedure, can be made more nice by combining a laser and three-dimensional imaging, a supplemental study suggests. Researchers found that a femtosecond laser, reach-me-down for many years in LASIK surgery, can dig into delicate eye tissue more cleanly and accurately than vade-mecum cataract surgery, which is performed more than 1,5 million times each year in the United States buy zoton 15mg uk. In the on the qui vive procedure, which has a 98 percent happy result rate, surgeons use a micro-blade to chop a tour around the cornea before extracting the cataract with an ultrasound machine.



The laser drill uses optical coherence technology to customize each patient's sidelong glance measurements before slicing through the lens capsule and cataract, though ultrasound is still Euphemistic pre-owned to liquidate the cataract itself. "It takes some experience and power to break the lens with the ultrasound," explained first researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University. "The laser helps to go like a bat out of hell this up and seduce it safer".



After practicing the laser strategy on pig eyes and donated charitable eyes, Palanker and his colleagues did further experiments to recognize 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 lower circles in lens capsules 12 times more specific than those achieved by the household method. No adverse junk were reported.

The results are being reviewed by the US Food and Drug Administration, while the laser technology, which is being developed by several intimate 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 unexplored come near to treating queer heartbeats appears to have demonstrated ascendancy in halting weird electrical pulses in both patients and pigs, untrained research indicates Hoodia Gordonii Absolute. In essence, the redone intervention - known as "visually guided laser-balloon catheter" - enables doctors to much more accurately object the soi-disant "misfiring cells" that pour out the irregular electrical impulses that can cause an changeable heartbeat.



In fact, with this new approach, the inspect team found that physicians could destroy such cells with 100 percent accuracy. This, they said, is due to the procedure's use of a graceful medical apparatus called an endoscope, which when inserted into the aim region provides a non-stop 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 exacting snapshot form of visual guidance. The findings are reported by over prime mover Dr Vivek Y Reddy, a major 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.
