Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.
Cataract surgery, already an very conservative and successful procedure, can be made more specific by combining a laser and three-dimensional imaging, a budding study suggests. Researchers found that a femtosecond laser, in use for many years in LASIK surgery, can cut into delicate eye web more cleanly and accurately than manual cataract surgery, which is performed more than 1,5 million times each year in the United States antehealth. In the ongoing procedure, which has a 98 percent attainment rate, surgeons use a micro-blade to lower a circle around the cornea before extracting the cataract with an ultrasound machine.

The laser methodology uses optical coherence technology to customize each patient's perception measurements before slicing through the lens capsule and cataract, though ultrasound is still worn to remove the cataract itself. "It takes some talent and energy to break the lens with the ultrasound," explained create researcher Daniel Palanker, an associated professor of ophthalmology at Stanford University. "The laser helps to speediness this up and make it safer".

After practicing the laser modus operandi on pig eyes and donated human eyes, Palanker and his colleagues did further experiments to support 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 reduction circles in lens capsules 12 times more faithful than those achieved by the ancestral method. No adverse belongings were reported.

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

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 commoners who function into their 70s and beyond will display cataracts at some point. That's why it's high-level to know the risks and symptoms of cataract, what to do to aside onset, and how to decide when it's schedule for surgery, experts at the American Academy of Ophthalmology (AAO) explained in a news programme release. People should get a baseline eye screening exam at majority 40, when early signs of disease and eyesight change may begin to occur, according to the AAO how stars grow it. During the visit, the ophthalmologist will spell out how often to schedule follow-up exams.

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

Smoking And Drugs Increases The Risk Of Eye Diseases

Smoking And Drugs Increases The Risk Of Eye Diseases.
A in the pink assembly helps mind against cataracts, while certain medications raise the risks of this general cause of vision loss, two new studies suggest. And a third investigation finds that smoking increases the hazard of age-related macular degeneration, another disease that robs common man of their sight 35 saal women ki chudai. The first study found that women who eat foods that have in it high levels of a variety of vitamins and minerals may be less appropriate to develop nuclear cataract, which is the most common type of age-related cataract in the United States.

The sanctum is published in the June problem of the Archives of Ophthalmology. The researchers looked at 1808 women in Iowa, Oregon and Wisconsin who took go his in a swat about age-related eye disease. Overall, 736 (41 percent) of the women had either atomic cataracts evident from lens photographs or reported having undergone cataract extraction.

So "Results from this review disclose that healthy diets, which reflect adherence to the US dietary guidelines - are more strongly linked to the lower occurrence of nuclear cataracts than any other modifiable jeopardy factor or protective middleman studied in this sample of women," Julie A Mares, of the University of Wisconsin, Madison, and colleagues said in a telecast release from the journal. The relocate study found that medications that increase awareness to the sun - including antidepressants, diuretics, antibiotics and the suffering reliever naproxen sodium (commonly sold over-the-counter as Aleve) - multiplication the risk of age-related cataract.

Researchers followed-up with 4,926 participants over a 15-year space and concluded that an interaction between sun-sensitizing medications and sunlight (ultraviolet-B) familiarity was associated with the development of cortical cataract. "The medications operative ingredients symbolize 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 info release. Their blast was released online in move of publication in the August picture issue of the Archives of Ophthalmology.
