BIONIC EYE FOR BLIND PEOPLE

A new revolution through biotechnology in the form of Bionic eye for blind people is about to come into existence shortly. Researchers feel that the bionic eyes for the blind will be ready for human trials by 2013. This bionic eye implant will help people who have lost their sight through traumatic injury or tumors or with diseases affecting eyes like glaucoma and retinal disorders. The implant is based on a small chip that is surgically implanted behind the retina, at the back of the eyeball. An ultra-thin wire strengthens the damaged optic nerve which servers to transmit light and images to the brain's vision system, where it is normally processed. According to the scientists, these implants do not require a functioning eyeball or optic nerve or visual pathways from eye to brain. The device can also be tuned for use in different environments, both indoors and outdoors. The users may have to wear special eye glasses containing a tiny battery-powered camera and a transmitter, which would send images to the chip implanted behind the retina. The device is both water-proof and corrosion-proof and is expected to will last for at least 10 years inside the eye. Although the device will not be able to restore the eye sight of the entire blind community, I feel many people will be benefited from the technology. Always it will be a nice feeling when technology helps for the better survival of human.

LASIK EYE SURGERY

Majority of people of this era are suffering from vision problem as they are exposed to computer, television and environment also acts as a main factor. Many people find it difficulty in having spectacles as they have to be cautious and need to carry everywhere. Also they are free to play with spectacles. Contact lens may help in those occasions but it may cause itching and should be too careful in handling it.  One should be more cautious while standing near fire as this contact lens would start melting and costs your eyes. The one and only solution is to go with Lasik eye surgery which gives you a 20/20 vision like exactly what normal eyes will get.  LASIK stands for Laser in Situ Keratomileusis commonly referred to simply as laser eye surgery. In this procedure highly specialized laser beam is used to treat refractive errors and to improve vision.

Not everyone can undergo this surgery. He/she should satisfy certain criteria will be considered as the suitable candidate for this surgery. One should be above the age of 18 and should not have frequent changes in refraction for at least a year. If your eyes got infected or injured recently, it’s better not to opt for such a procedure as it might impair your vision instead of improving it. People suffering from glaucoma, cataracts and a few other eye problems cannot be treated effectively with laser eye treatment. Different kind of Lasik surgical treatments such as Standard Lasik, Wave front-guided Lasik, Wave front-optimized Lasik are performed based on the eye condition. This would be decided by the consulting doctor after examining your eyes under various tests.
