lasik

LASIK is the newest and safest laser procedure available for refractive errors today.

What is a refractive error?
For a person to see clearly, rays of light need to be focused precisely onto the retina. The retina lines the inner aspect of the eyeball just like the film of a camera lines the back wall of the camera.
The retina converts the light rays into nerve impulses, which are then transmitted through the optic nerve to the brain. Our cornea and lens focus the light rays entering the eye onto the retina. If the image is not focused properly and the retina does not recieve a clear image this condition is called a REFRACTIVE ERROR. There are three types of refractive errors, each of which we can correct with excimer laser.

1. Myopia -"nearsightedness":

a person with myopia has blurry vision at distance and is in clear focus at near. The rays of light that are focused by the cornea and lens come into focus in front of the retina and the image is blurred.

2. Hyperopia -"farsightedness":

is the opposite of myopia. Distant objects are clearer than near ones. The rays of light that are focused by the cornea and lens come into focus behind the retina, and images at all distances may be unclear.

3. Astigmatism is a condition which can blur vision both at near and far. A ideally shaped cornea resembles a sphere e.g. half a grapefruit, while an astigmatic eye resembles an irregular surface such as a back of a spoon which is curved more in one direction than the other, thereby having multiple areas to focus and may be unclear at all distances.


	All three types of refractive errors can be corrected through laser vision correction. LASIK is a proceedure that is used to correct or reduce moderate to high levels of refractive errors. During a lasik proceedure, only topical drop anesthesia is used. No systemic anesthesia is needed.

      LASIK is a procedure that is used to correct or reduce moderate to high levels of refractive errors. During a lasik procedure, only topical drop anesthesia is used.

(1) There is no need for needles or sutures. We use an instrument called a microkeratome to create a very thin flap of tissue in the cornea.

(2)   Then the excimer laser is carefully focused and a microthin layer of tissue is removed by the laser beam.

(3) The flap is then replaced without sutures and the patient returns home.

(4)   The effect of the removal of tissue results in better focusing onto the retina, and clearer vision with out corrective contact lenses or glasses.

Anesthetic Drop are applied to the eye

A hinged flap is created by the surgeon and folded back

The inner corneal layer is reshaped with the laser

The surgeon closes the flap

The flap adheres naturally and securely
