A researcher from UK is working on a project of development of
adjustable artificial lenses which will be made up from the same material found
in smartphone and TV screens. These adjustable lenses will help in improving
vision of older people with presbyopia and cataract.
When people age their eye lenses lose elasticity and flexibility and it
leads to a condition known as presbyopia, very common in people ageing above 45
years and can require optical aids like power glasses.
The researcher is of Indian origin, Devesh Mistry who is a postgraduate
in the school of physics and Astronomy at University of Leeds working on liquid
crystal to create truly adjustable artificial lens.
He said "As we get older, the lens in our eye
stiffens, when the muscles in the eye contract they can no longer shape the
lens to bring close objects into focus," he said. "Using liquid
crystals, which we probably know better as the material used in the screens of
TVs and smartphones, lenses would adjust and focus automatically, depending on
the eye muscles' movement."
He is also working to replace the diseased lens in the eye a
new generation of lenses and intraocular lens to rejuvenate eye sight.
The protocol would be ready by 2018 and within few years
lens can be seen being implanted into eyes in a quick and straightforward surgical
procedure.
