It came into use in the 1980s, which helped people get rid of eyeglasses and contacts to threat their vision problems. Eyeglasses and contacts are only served as aids to help people get a clear vision, while LASIK aims at correcting the vision problems. Therefore, since its inception, LASIK gains many popularities. Those who have successfully undergone a laser eye surgery procedure say they are so happy that they can see a world as clear as before without the help of glasses and contacts.

As for the LASIK eye surgery, there are several commom questions need to be clarified.

First, how does LASIK achieve to make eyesight corrected? This may be the question many people want to know. LASIK, by utilizing laser to extract bits of tissue from the cornea, makes visual images be focused directly on to the retina, but not makes visual images be focused by the asistance of eyeglasses or contact lenses. That is to say, if your cornea is not shaped correctly to fit the dimensions of your eye, the LASIK eye surgery is able to reshape your cornea from within the eye itself by laser.

Second, what do you have to pay atterntion to before the surgery? This is another important question for those who are going to have one. There are some tips. Get a thorough eye examination. Only by this way can doctor get a general idea of your eye condition, and make right decisions when going on the surgery.

Do not wear your glasses for at least a month before the surgery. When you tell a doctor that you want to have a LASIK eye surgery, you will be advised not to wear your vision aids for 2 to 4 weeks, whether eyeglasses or contact lenses. Because if you will wear vision aids prior to the surgery, it is hard for your eye cornea to return to its natural shape. In addition, some cheap contact lenses are easy to change the shape of the cornea. So it is fairly significant not to wear vision aids for at least a month before the operation. Do not use any lotions, creams, make-up or other products around the area of the eyes for some time before the operation.

Third, what need to be done during the surgery? Someone may get nervous before a surgery, the following are hoped to be helpful to ease your tension. For you may feel painful during the surgery, therefore, before the operation, you will receive anesthetic drops in each of your eye. What's more, you will be positioned under the laser equipment by placing you on a table and you are required to look up at a small blinking light. During the surgery, the doctor will use a special instrument to hold your eye wide open to help them perform the LASIK surgery. The operation will be processes from one eye to the other, therefore, when one of your eyes is under operation, the other one of your eyes is protected and covered by a shield. And then your eye will be cut into a small incision which is to be done for exposing the cornea. Then the doctor can reshape and repair your eye by laser technology. After it has been done, the flap will be put back into the position. Don't worry about the flap it will heal on its own for some time. And then, you can go home after a couple of hours.

As for the recovery time, it varies from person to person. Always keep close contact with your doctor before and after the surgery for most appropriate advices, and for the best recovery and healing of your vision.
