The Mechanics of Lasik

By Paul Notts

Lasik is one of the most popular and effective vision correction surgeries. Not only is the procedure highly effective at correcting vision problems, but it also has a short recovery time. As a result of Lasik eye surgery, most patients will be able have their vision correct to 20/20 vision.

During the first step of the surgery, the doctor will create a very thin flap in the patient's cornea. This is done in a very precise manner, so that this flap can be folded back, exposing the corneal tissue.

Next, an excimer laser is used to reshape the patient's cornea by removing small pieces of the corneal tissue. The purpose of this reshaping is to allow the eye to focus correctly on the retina, so that the vision problem is corrected.

Once the cornea is reshaped, the previously created flap is unfolded and allowed to fall back into its proper place. Since this flap will heal naturally, there is no need for the Lasik surgeon to perform suturing.

Lasik surgery is usually an outpatient procedure, which can usually be performed in less than half an hour. During the procedure, your surgeon may administer anesthetic eye drops. Also, it is highly recommended that you have someone drive you home after the surgery.

After arriving home, you may be advised to place cold compresses on your closed eyes, as well as rest. If need be, your doctor may tell you to take over-the-counter pain medications every four hours. Be aware, there may be some residual eye sensitivity for a day or two.

A possible side effect of the surgery is the patient's vision may fluctuate a bit for the first few weeks, and they might notice some blurred vision. If there is any redness or irritation, this can be relieved with eye drops which the doctor will recommend.

Eye makeup and swimming should be avoided during the first two weeks following the surgery. Sunglasses can also be worn, and the patient should avoid any type of contact sports until the doctor advises otherwise.
