Many of us suffer from the problem of farsightedness of hyperopia. The problem is most visible in people who are around forty. Due to this condition a person would not be able to see what is close to his eyes. So reading from a book or a computer screen becomes very difficult if not impossible without the aid of reading glasses. At the same time since this condition generally happens pretty late in life it becomes kind of difficult for many to shift to reading glasses. In such cases proves to be the best available option.
Lasik is a kind of refractive eye surgery where the retina of your eye is adjusted to make it go back to normal. Let us first understand how the eye surgery is done. First a mild anesthetic will be administered. Also eye drops are used to numb the eye and avoid pain during the operation. Though the operation is pain free there have been patients who have complained of discomfort. Once the eye is numb, a little device known as the microkeratome is attached to a suction ring placed on the eye.
The microkeratome has a blade which cuts a thin flap on the surface of the cornea. The doctor will next fold back the flap and expose the stroma which is basically a layer of tissue. The stroma is searched for debris and is then dried. 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. Once through, the flap is put back to position and an eye patch is provided to allow it to heal.
It takes about a few weeks for your eye to come back to normalcy and for the effects of the operation to show. There can be a few initial complications like double vision, glare, and halo. But most of them subside in a few weeks.
Apart from hyperopia, eye surgery is also effective in two other kinds of eye conditions-myopia and astigmatism. 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. In both these cases this surgery is quite effective.
