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.

Acupuncture Can Treat Some Types Of Amblyopia
Acupuncture Can Treat Some Types Of Amblyopia.
Acupuncture may be an noticeable scheme to treat older children struggling with a certain form of lazy eye, late research from China suggests, although experts say more studies are needed. Lazy eye (amblyopia) is essentially a status of miscommunication between the brain and the eyes, resulting in the favoring of one eye over the other, according to the National Eye Institute. The turn over authors noted that anywhere from less than 1 percent to 5 percent of mobile vulgus worldwide are affected with the condition. Of those, between one third and one half have a personification of lazy eye known as anisometropia, which is caused by a difference in the degree of nearsightedness or farsightedness between the two eyes.
Standard curing for children involves eyeglasses or contact lens designed to correct heart issues. However, while this approach is often successful in younger children (between the ages of 3 and 7), it is triumphant among only about a third of older children (between the ages of 7 and 12). For the latter group, doctors will often chore a patch over the "good" eye temporarily in addition to eyeglasses, and healing success is typically achieved in two-thirds of cases.
Children, however, often have trouble adhering to area therapy, the treatment can bring emotional issues for some and a reverse form of lazy eye can also accompany root, the researchers said. Study author Dr Dennis SC Lam, from the segment of ophthalmology and visual sciences and Institute of Chinese Medicine at the Joint Shantou International Eye Center of Shantou University and Chinese University of Hong Kong, and his colleagues clock in their observations in the December dissemination of the Archives of Ophthalmology.
In the search for a better option than patch therapy, Lam and his associates set out to research the potential benefits of acupuncture, noting that it has been used to treat dry eye and myopia. Between 2007 and 2009, Lam and his colleagues recruited 88 children between the ages of 7 and 12 who had been diagnosed with anisometropia.
About half the children were treated five times a week with acupuncture, targeting five unambiguous acupuncture needle insertion points (located at the prune of the leader and the eyebrow region, as well as the legs and hands). The other half were given two hours a age of plat therapy, combined with a minimum of one hour per day of near-vision exercises such as reading.
After about four months of treatment, the examine team found that overall visual acuity improved markedly more among the acupuncture crowd relative to the patch group. In fact, they noted that while lazy eye was successfully treated in nearly 42 percent of the acupuncture patients, that form dropped to less than 17 percent in the midst the patch patients.
