Laser Eye Surgery: What Happens And Why
By Frank Montes
Laser surgery often called lasik surgery, is a procedure that allows your sight to be corrected. There are actually many different types of this surgery and the equipment often changes from one doctor to the next. What the overall benefit is, though, is simple. By adjusting the shape of your cornea, you can improve your sight considerably. Like any other surgery, there are risks involved. But, the benefits are there for most that have laser surgery.
The cornea of your is the film of tissue that covers your pupil. In a normal with no vision problems, it has a very specific shape that is even and rounded. In an individual that has near sightedness or far sightedness, the cornea is misshapen to some degree. By bowing out or changing shape in just a bit or a lot of area, the cornea distorts your vision, which leaves you with problems like not being able to see things that are far away
or being unable to see things up close.
With the help of laser surgery, though, this can be changed. The doctor will remove part of the cornea from your on only three sides, creating a flap. From here, he will use a high powered laser to change the shape of the stroma, which is the tissue that lies under the cornea that’s been removed. By shaving that to the desired level, he improves your vision. When the cornea lays back over the eye, it now lays there correctly, with the right curve which ultimately improves your vision.
The laser surgery procedure is one that should be carefully considered because there are some risks. But, if the procedure goes correctly, within some time after healing has been complete, your eyes can actually improve in vision. Some individuals gain excellent sight. Others improve. Talk to your doctor about the benefits that can come from your improvements.
