Lasik Eye Surgery Information

What is Lasik eye surgery?

laser eye surgery processIt is a type of surgical procedure that rectifies certain visual problems, hence reducing an individual’s dependency on contact lenses or glasses. The term Lasik in full is Laser-Assisted in Situ Keratomileusis, and it permanently transforms the shape of your cornea, a clear covering at the front of your eye, using an excimer laser.

It is the most popular type of refractive surgery and it is intended to refract or bend light rays to focus specifically on your retina instead of at some point short or beyond your retina. Its main goal is to produce a sharper, clearer vision.

How does Lasik Surgery work?

During the procedure, a trained eye surgeon (in the particular field) begins by creating a thin, precise hinged corneal flap by means of a microkeratome. He/she then pulls back the flap exposing the underlying corneal tissues, then uses the excimer laser to reshape (ablates) the cornea in an exclusive pre-specified pattern for every patient. The surgeon then gently repositions the flap onto the underlying cornea devoid of sutures.

Who is eligible for this type of surgical procedure?

If you are suffering from any of these eye or vision problems, then you may consider going for this surgery.

  • · Nearsightedness or short-sightedness (myopia)

You are said to be suffering from this vision problem when your cornea curves very sharply or when the eyeball is a bit longer than usual, thus resulting to light rays focusing on the front of your retina resulting to blur distant vision. This means that you can see things that are near more vivid, but not those far away from you.

  • · Farsightedness or long-sightedness (hyperopia)

This occurs when your eyeball is shorter than average or you cornea is very flat, resulting in light focusing behind rather than on it. This in turn results to near vision and at times distant objects looking blurry.

  • · Presbyopia

This is a vision problem caused by age-related eye changes that lead to the steady loss of your visual strength, or your eyes’ capability to actively change focus on near objects.

  • · Astigmatism

This happens when your cornea flattens or curves unevenly, thus resulting to disruption of your focus of distant and near vision.

Benefits of Laser eye surgery

  • · It is capable of correcting most levels of hyperopia (farsightedness), myopia (nearsightedness), and astigmatism.
  • · Due to the fact that the procedure is guided using a computer, it is very precise and the outcomes are very accurate.
  • · The surgical procedure is quick, usually takes approximately 5 – 10 minutes only and in general it is painless.
  • · In most situations, a single treatment will provide you with the desired results; nevertheless, enhancements are possible if you need them, even several years after the first surgery.

Disadvantages of LASIK

  • · Results may vary from one patient to another due to the fact that they heal differently.
  • · To some people, the surgical procedure may worsen the dry-eye symptoms.
  • · In some situations, the procedure may make certain elements of your vision worse, including your night visions with halos and glare.
  • · Although it happens in rare situations, the surgical procedure may worsen your vision and make them difficult to correct even with contact lenses or glasses.
