LASEK Eye Surgery

How It Works – LASEK also known as laser epithelial keratomileusis is a new procedure in which the laser energy is applied directly to the eye’s outer surface for reshaping and vision correction.
For better understanding here are some differences between some procedures.
First of all for exemple with LASIK, a thin flap is cut into the eye’s surface and then lifted. Then the laser energy is applied to the eye for reshaping and the flap is replaced that – to serve as a type of natural bandage for a quicker healing.

An eye doctor using PRK does not cut a thin flap into the eye’s surface, like it does with LASIK. Laser energy is applied directly to the eye’s surface. The epithelium is removed absolute completely by laser energy during a PRK procedure, and eventually grows back.

A LASEK operation implyes preserving the thin epithelial layer by lifting it from the eye’s surface before laser energy is applied. After the LASEK operation, the epithelium is also replaced on the eye’s surface.

The LASEK procedure is used mostly for people with corneas that are too thin or too steep for LASIK, when it can be real difficult to create a thicker LASIK flap. LASEK was created to reduce the chance of problems that occur when the flap created during LASIK procedure does not have the ideal thickness or diameter.

The LASEK Procedure is not so simple, but it isn’t so hard as well.

During the LASEK

During the LASEK operation your doctor will use local anesthesia.
Then he or maybe she will cut the epithelium, or outer layer of the cornea, with a fine blade. Then the surgeon covers the eye with a alcohol solution for approximately one minute.After sponging the alcohol solution from the eye, the doctor uses a tiny hoe to lift the edge of the epithelial flap and softly fold it back out of the way.After this he/she uses an excimer laser to sculpt the corneal tissue below. After, the epithelial flap will be placed back on the eye with a type of spatula.

LASEK Procedure

According to some doctors who perform LASEK procedure, the flap edge heals in about one day, though patients usually wear a bandage contact lens for maybe four days to protect the eye.
If your eye will feel irritated during the first day or or maybe two you must know that is normal. With LASEK procedure compared with LASIK one, it often takes a little longer to recover good vision (it depends four – seven days) but this depends from a person to another. Also, you may experience a little more pain with LASEK procedure compared with LASIK procedure.

In some studies the LASEK procedure has been associated with a faster healing process of sensation or nerve function in the cornea, compared with LASIK.

Also,it can cause dry eye less frequently than LASIK procedure.
However, talk to your eye doctor and he/she will tell you exactly what kind of operation is better for you.
