Also Eye Drops Are Used To Numb The Eye And Avoid Pain During The Operation

Health, Medicine.

Basics of lasik eye surgery - eye surgery comes with the promise of improving one' s vision permanently so that the need for glasses or contact lenses is no longer there. In a way, you discover new liberty and freedom. So you are no longer dependent on them.


How is it done? - first a mild anesthetic will be administered. It takes about five to ten minutes to complete the operation. Also eye drops are used to numb the eye and avoid pain during the operation. Once the eye is numb, a little device known as the microkeratome is attached to a suction ring placed on the eye. Though the operation is pain free there have been patients who have complained of discomfort. The microkeratome has a blade which cuts a thin flap on the surface of the cornea.


The stroma is searched for debris and is then dried. - the doctor will next fold back the flap and expose the stroma which is basically a layer of tissue. Now the surgeon will ask you to focus on a fixed spot while he, with the aid of laser mends the corneal tissue according to results of pre - operation examination. Which are the conditions that are treated? Once through, the flap is put back to position and an eye patch is provided to allow it to heal. Basically eye surgery is used to cure three main types of eye conditions - myopia, hyperopia and astigmatism.


Hyperopia, also known as farsightedness, is the other way round. - myopia, also know as nearsightedness is the problem of not being able to see what is far away without glasses. Astigmatism is something different where the patient has irregularities in his cornea which as a result distorts the image formed on the retina of the eye. An ideal candidate for this surgery should be over 21 years of age. Who is an ideal candidate? The person should not be into contact sports or any similar physical activities.


Pregnant women are also not eligible for that surgery. - the visual stability over the past year should be good and there should not be any history of previous eye diseases or eye injury. What are the risks? Problems that might be caused due to this surgery are double vision, and halo, glare. This eye surgery comes with its own set of risks and they should always be considered seriously before you actually sign - up for an operation. One' s nighttime vision can also be affected, especially for certain operation procedures.


Even permanent blurry vision and diminished contrast may be the effects of this operation.
