Lasik Eye Surgery Risk Factors You Need To Know

All surgeries have benefits as well as risks. There is always the possibility of Lasik eye surgery affecting your vision. You should thus consider the risks it carries and then take your decision.

You must make an informed decision. And thus you must learn the facts about Lasik eye surgery. You must know how the eye works and learn the intricate details about the cornea. Once you know about all this you should take time to find a good eye surgeon for yourself. One of the biggest measures you can take to reduce the risks is to appoint a talented and practiced surgeon as your surgery will be hugely dependent on who does it.

What is Lasik? Basically, it's an acronym for Laser-Assisted In Situ Keratomileusis and is a laser eye surgery procedure that can permanently correct your vision. The operation has best results in patients who suffer the following conditions: from moderate to high degrees or myopia (nearsightedness), low to moderate conditions of hyperopia (farsightedness), astigmatism associated with myopia, and thick corneas.

People with normal vision can perceive objects lucidly, for the lights and shadows that play on and around the object are brought to a focal point by the cornea and the lens of the eye. Ideally, the curvature of the cornea should evenly match its length. However, people with astigmatism, myopia, or hyperopia, have irregularly structured corneas. Thus the objects appear hazy or disfigured.

Lasik targets to change the shape of the corneas by an accurate removal of the corneal tissue. This removal corrects the eye focusing ability. So what are the risks?
1. The most conspicuous risk is that you might totally lose your eyesight. This could happen if your diagnosis had been wrong or the operation should not have been performed because of some other serious medical affliction. You could be pregnant, have cataracts, rheumatism, diabetes, glaucoma, lupus, etc. Lasik eye surgery must not be performed under such circumstances.

2. Another grave danger is that you will lose perception, insight or acuteness of vision because you had large pupils and very poor eye sight in the first place.

3. If you have dry ear syndrome it could be made with surgery. Again, it's vital you discuss this with your surgeon before you agree to have any surgical work performed.

4. You might also permanently have hazy vision, reduced contrast, or see blurry ghost-like shapes that do not exist. In many cases, these are temporary and will be pointed out as risks by your surgeon.
