How Does Lasek Work?

LASEK which is an acronym for Laser Assisted Sub-Epithelial Keratomileusis is one of the younger techniques for executing eye surgery and rectification of vision.

LASEK as an surgical procedure is worthy for all of those that can not get the more frequent surgery, LASIK, because of several grounds, including to fragile cornea or too straight cornea. External factors, such as line of work may play a role in the selection of surgical process method. For instance, athletes and airplane pilots may fair better without a flap in their cornea.

If you want to do an LASEK surgical procedure on your eyes you are most likely above 18 years old, or that your prescription glasses or contacts hasn’t varied for at least a year. If that is the case, anyone with Myopia (short-sight), Hyperopia (long-sight) or Astigmatism can do the the surgical procedure.

Before we go through the how you eye function. Our eyes are very much dependant on light. If there wasn’t some light you would not be able to visualize at all. When the light rays hit our eyes of the outside cornea it is bend, or refracted so that it becomes adjusted on the inside and back of the eye, the retina. The retina is where the “picture” is created and where the optic nerve pick up the picture and transmit it to the mind where we “see” it.

If you have any kind of the above named vision problems the flexing, or refraction of light is the problem that causes you vision to go bad. The light rays become cracked and the picture on the optical nerve go out of of focus.

Omitting any pre- and post examinations the following will in a great sense deal with how a LASEK process is executed.

To commence you will have anesthetic drops in your eyes to take away any pain during the surgical process. Next, an lid speculum is attached to the eyelids to hold them apart through surgical process and so that the doctor doing the surgery may have full access to the eye during the procedure.

Next, a tiny retinal cone is placed on your eyes outer surface off the cornea. In this retinal cone a few drops of a mild alcohol solution is dropped. This alcohol softens the outer layer of the cornea. Within second the doctor then removes the alcohol and the area is rinsed in good order. The doctor may now take away the outer surface of the cornea and reveal the central cornea layer, called the stroma. As you can read from the description no cutting tools is used around your eye during the procedure. The outer surface of the cornea is just lifted back once the operation is finished.

The next stage of of the operation is when the laser is employed. In nearly every surgery a special laser is applied, called the Excimer laser. This laser will send pulsations of UV-light into the eye. This UV-light is used to evaporate enough of the central cornea layer to remold it as much as needed to rectify the vision.

When the laser has completed its job the cornea surface is put back and a protecting bandage lens is put in to protect the initial healing period. This lens is taken away inside a few days, and inside a workweek, or two you are able to drive and work again.
