LASIK Vision surgery is used to correct different eye conditions such as Myopia also known as “nearsightedness” or “short sightedness”,

Hyperopia also known as "farsightedness" or "long sightedness", and Astigmatism.

It uses a laser to correct imbalances in the Cornea and Retina of patients and, although it's similar to PRK surgery, there are few side effects associated with its use.

It's the most modern form of corrective Laser Eye Surgery in use today, and replaces radial keratotomy, which was used previously by ophthalmologists.

The operation essentially creates a tiny flap over the eye, and then folds it so that the laser can remodel the tissue underneath the flap. After the surgery is complete the flap is put back into its original position and then is allowed to heal.

There are several different steps to Lasik Surgery, starting with the preoperative stage.

During the preoperative stage, patients need to stop wearing their Contact Lenses at least 5 days before the surgery takes place, and up to 21 days before.

If the patient wears hard lenses, as opposed to soft lenses, then they may be asked to stop wearing them as much as 6 weeks before the surgery takes place, with an additional six weeks for every three years that they have been worn.

The ophthalmologist will examine your Cornea to figure out how thick it is, and will also use a device called a topographer to measure the contour of the surface. The topographer is actually a laser itself, although a low powered one, that creates a three dimensional model of the surface of the eye.

This process can also be used to detect if the cornea has an irregular shape, which could be a sign of Astigmatism. The surgeon will then take this information and determine how much tissue will need to be removed from the cornea during the procedure.

Patients are also asked to take an antibiotic before undergoing their LASIK vision surgery just to cut back on the chance that any infections will form.

During the operation itself, you are fully awake and conscious. Sometimes the doctor will give you a mild sedative or a Valium, but nothing that will completely knock you out. After the fixture is attached to your face, a suction ring is applied to the cornea to keep it from moving around.

You might have some blood vessels burst when this happens, but it's not serious and the redness from the ocular bleeding will go away in a matter of weeks. Then, a flap is created directly on the cornea using either a tiny metal blade or a device known as a femtosecond laser. The flap has a hinge on one side, and the surgeon will then fold the flap back to reveal the stroma underneath.

A laser then vaporizes the tissue around the stroma to remove any irregularities. Most of this tissue is 10 or 20 micrometers thick, an incredibly small amount.

In case the eye moves around, the laser tracks its position more than 4,000 times every second, allowing it to compensate for any movement. The laser blasts themselves only last about 10 nanoseconds.

LASIK vision surgery can be a viable way to treat troublesome Vision Problems but you should always take steps to Protect Your Eyesight so you never even have to get surgery to begin with.
