Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.
Cataract surgery, already an extraordinarily justifiable and successful procedure, can be made more precise by combining a laser and three-dimensional imaging, a creative study suggests. Researchers found that a femtosecond laser, used for many years in LASIK surgery, can abridged into delicate eye tissue more cleanly and accurately than manual cataract surgery, which is performed more than 1,5 million times each year in the United States vigrx. In the going round procedure, which has a 98 percent name rate, surgeons use a micro-blade to cut a circle around the cornea before extracting the cataract with an ultrasound machine.

The laser scheme uses optical coherence technology to customize each patient's comprehension measurements before slicing through the lens capsule and cataract, though ultrasound is still used to remove the cataract itself. "It takes some technique and energy to break the lens with the ultrasound," explained edge researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University vigora lido spray use. "The laser helps to step on it this up and make it safer".

After practicing the laser procedure on pig eyes and donated woman eyes, Palanker and his colleagues did further experiments to confirm 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 engraving circles in lens capsules 12 times more truthful than those achieved by the stock method. No adverse effects were reported.

The study, reported in the Nov 17, 2010 debouchment 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.

Smoking And Drugs Increases The Risk Of Eye Diseases

Smoking And Drugs Increases The Risk Of Eye Diseases.
A fit legislature helps guard against cataracts, while certain medications raise the risks of this frequent cause of vision loss, two new studies suggest. And a third analysis finds that smoking increases the risk of age-related macular degeneration, another disease that robs clan of their sight antehealth. The first study found that women who eat foods that contain high levels of a brand of vitamins and minerals may be less likely to develop nuclear cataract, which is the most common type of age-related cataract in the United States.

The analyse is published in the June issue of the Archives of Ophthalmology. The researchers looked at 1808 women in Iowa, Oregon and Wisconsin who took business in a examine about age-related eye disease treatment. Overall, 736 (41 percent) of the women had either nuclear cataracts comprehensible from lens photographs or reported having undergone cataract extraction.

So "Results from this consider indicate that healthy diets, which reflect adherence to the US dietary guidelines - are more strongly reciprocal to the lower occurrence of nuclear cataracts than any other modifiable risk factor or protective particular studied in this sample of women," Julie A Mares, of the University of Wisconsin, Madison, and colleagues said in a announcement release from the journal. The second study found that medications that increase hypersensitivity to the sun - including antidepressants, diuretics, antibiotics and the pain reliever naproxen sodium (commonly sold over-the-counter as Aleve) - growth the risk of age-related cataract.

Researchers followed-up with 4,926 participants over a 15-year days and concluded that an interaction between sun-sensitizing medications and sunlight (ultraviolet-B) leaking was associated with the development of cortical cataract. "The medications active ingredients report a broad range of chemical compounds, and the specific mechanism for the interaction is unclear," Dr Barbara EK Klein and colleagues at the University of Wisconsin, Madison, said in the intelligence release. Their blast was released online in advance of publication in the August print issue of the Archives of Ophthalmology.

The Number Of Cataract Disease Increases As The Extension Of Human Life

The Number Of Cataract Disease Increases As The Extension Of Human Life.
Americans are living longer than ever before and most ancestors who energetic into their 70s and beyond will expand cataracts at some point. That's why it's foremost to know the risks and symptoms of cataract, what to do to interval onset, and how to decide when it's set for surgery, experts at the American Academy of Ophthalmology (AAO) explained in a dispatch release. People should get a baseline eye screening exam at mature 40, when early signs of disease and sight for sore eyes change may begin to occur, according to the AAO bangladeshi song hot. During the visit, the ophthalmologist will disclose how often to schedule follow-up exams.

People of any age who have symptoms or are at jeopardy for eye disease should make an appointment with an ophthalmologist to establish a grief and follow-up plan. Risk factors for cataract take in family history, having diabetes, smoking, extensive disclosure to sunlight, serious eye injury or inflammation, and prolonged use of steroids, especially combined use of word-of-mouth and inhaled steroids.
