Four Kinds of Laser Eye Surgeries

In modern society, having a laser eye surgery is not only a fad, but also a more preferable way to have eyesight problems corrected rather than wearing eyeglasses. There are four kinds of laser eyesight correction surgeries which are thought to be necessary to be listed to help patients get a general view.

This first one is the flap techniques, among which the LASIK is the commonly applied one procedure. During the surgery, the surgeon cuts a small flap in the cornea, if LASIK applied, a laser beam is used to create the flap and remove the extra tissue, so that the cornea can be reshaped and regain the ability to focus objects. This procedure can also be achieved by photoablation techniques in which a kind of cool heat, mainly composed of ultraviolet radiation, is used to impair the excess tissue. Then the tissue is taken off from the cornea. The difference between flap technique and photoablation technique is that the latter comes to comparatively secondary. However, as it known to all that problems are inevitable to emerge during any surgery, so do flap techniques, during which, the flap may be put out of place causing eye soreness and blurry vision but this is of low probability, a million to one. In addition, a perforation in the eye and an irregular flap can happen at times, resulting in seeing “floaters” in vision, but those often happen when older equipment is used.

The second one is the thermal techniques, which are mainly applied to cure farsightedness. It, in both laser technique and electric probe, is achieved by heating up the pupil with thermal heat 8-16 tiny burns. Thus the cornea can be reshaped to be steeper.

The third one is the corneal incision methods. This technique is accomplished based on the principle of changing the surface of the cornea, so that vision errors are fixed. However this technique is proceded in a traditional way by using a diamond-tipped knife to make a tiny cut in cornea, it has been replaced by laser technology now.

The forth one is the implants. They are done by putting contact lenses right behind the cornea forever, which are referred as intra-ocular contact lens implant. This technique is usually applied when one’s cornea are so extremely deformed that eye problems can not be corrected by other surgeries.

After the operation, a few days or last up to a month will be taken for one to get recovered which varies from person to person. It is worth to notice that in the course of healing, people should take good care of their eyes, or some issues will occur, for that with any operation, there is certainly a risk of infection. Therefore, it is advisable not to rub eyes, and take along eye drops, which can serve as a help to keep eyes from getting dry. If your eyes are unfortunately get infected, go to see your eye doctor as soon as possible, in case of slowing the course of healing.

That’s all the kinds of laser eye correction surgeries above. If you have had enough of the trouble of wearing eyeglasses and contact lenses, it is the time for you to try the new, which will definitely surprise you a lot. Do not be worried about the accidents mentioned above, study show that laser issues happen in less than 1% of eye operations done today. Anyhow, no matter what kind of surgery you are intended to take, do consult a professional eye doctor. If permissible, consulting another one or two ophthalmologists will be great.
