Ophthalmology
Ophthalmology is the medical specialty dedicated to the study of the eye's structure and function, and to the diagnosis and treatment of diseases affecting them.
In a normal eye, the cornea and the lens focus the light rays entering the eye to a single point close to the retina. The retina, or the light sensitive tissue in the back of the eye, converts light impulses into nerve impulses. The nerve impulses move along the optic nerve to the brain, which interprets the impulses allowing the person to "SEE". Three primary refractive errors might occur. These are Myopia (near sightedness), Hyperopia (far sightedness) and Astigma.
Lasik is an acronym for Laser in-situ Keratomileusis, which simply means "to shape the cornea within using a laser." It corrects vision by reshaping the cornea (outer window of the eye) so that rays focus more precisely on the retina, thereby reducing or eliminating refractive errors.
It is done by using an instrument known as a microkeratome which cuts a thin flap of corneal tissue, then the laser is fired to remove predetermined amount o tissue& the corneal flap is placed back in its position without any stitch. This is done by use of topical anaesthesia. As it is done under topical anaesthesia, patient mobilisation is early & there is no post-operative pain, less corneal scarring & haze.
A large number of patients from neighbouring states and neighbouring countries like Bangladesh, Sri Lanka, Maldives etc. are regularly referred to our institutions. The Ophthalmology department offers complete eye care to many such patients.
Management of eye ailments, both anterior and posterior segments are provided at the centre.
