Artificial lenses- Boon to cataract patients

A lens implant that can change focus like a natural lens promises to make cataract patients’ eyesight almost as good as it was when they were young.The device, which is being developed by Jin-Hui Shen, an ophthalmologist at Vanderbilt University’s School of Medicine in Nashville, Tennessee, contains six overlapping lenses.// As the muscles in the eye relax, the overlap increases, allow...

Microscopic lens monitors heart problems

An innovative way to predict risk of surgery. Lens as thick as two strand of human hair, can predict when complications are developing after coronary bypass surgery. The main problem with bypass surgery is that arteries tend to re-block, risking heart attack and requiring further treatment.// If changes in blood flow through the artery could be detected at an early stage, it's possible th...

Contact Lenses Found To Slow Progression Of Myopia in Kids

Children who wear rigid gas permeable ( RGP ) contact lenses can minimize the chances their myopia will worsen over time// say researchers according to a recent study .

Kids who wore the RGPs generally needed about two weeks to adapt to the l...

Reduce eye infection through new-age contact lenses

It is possible to reduce eye infections like keratitis by wearing the latest silicone hydro gel lenses for longer hours, reports British Journal// of Ophthalmology. Scientists showed that study done on contact lens wearers for daily wear or extended wear contact lenses have varied results on the incidence of non-severe keratitis and severe keratitis. The researchers had observed conta...
