A Detailed Introduction about Lasik Corrective Eye Surgery - By: AdamDouglas

People may get easily annoyed when wearing eyeglasses or contacts, as the eyeglasses sometimes affects your image and contacts hurt your eyes. In the ancient time, there is nothing people can do to change the condition except for wearing eyeglasses. However, nowadays people can restore the vision by the method of Lasik corrective eye surgery in a quite short time.

Firstly, patients are required to lie down on the bed and a kind of equipment is used to hold the eyelids during the surgery, which only take one minutes to setup everything once the surgery gets started.

Now, it is time to carry out the operation.

A thin and circular flap is cut in the cornea with the help of a special knife, named microkeratome. The excimer laser is considered as a good alternative because of its high accuracy and good after-surgical outcomes.

After cutting the flap on the cornea, it is time to remove the additional cornea tissues. The ultraviolet light beam, which comes out from the excimer laser, is helpful to get rid of the additional tissue in small pieces. In order to remove the optimal quantity of the corneal tissues throughout the operation, the computer is used to control the excimer laser accurately. As a result, the laser can stop at anytime and at anywhere which does a great favor to the patients. There is also one to mention here, that is when you hear or smell something special during the operation, please do not feel nervous, because the clicking sound from the laser and the acidic smell from the removal of tissues are quite normal in the surgery.

Having all the useless tissue removed, the flap is restored to cover the missing area and the cornea returns back to its normal condition, being able to focus on the objects clearly, which means you eyesight is good again.

In fact, the whole surgery is extremely quick and pain-free, being different with other operations. Generally, the eye drops are used before the surgery to anesthetize the eyes, and if your eyes feel uncomfortable before the operation, you can take some mild sedative to be an aid. Patients are able to keep conscious all the periods and can walk around right after the surgery is finished.

Besides, if you would like to have both your eyes operated, you are recommended to take a break between two eyes, lasting about one week or two on the consideration of the safety of your eyes.
