Although popularly we know it as lasik eye surgery it is also known as refractive this surgery or vision repair surgery. The last name describes the surgery best as it actually repairs one's vision. What does is that it reshapes your cornea thereby allowing you to have normal vision without any external aid like glasses or contact lens. And recently there has been a lot of advancement in the field of this operation.

They has been embraced by many a patient over the last decade to correct some specific eye defects. It has caught the imagination of people and has been gaining popularity every year. But this surgery does have its own effects and it varies from one patient to another. So before you actually decide on getting an operation done, you should always consider the pros and the cons.

Basically this is used to cure three main types of eye conditions - myopia, hyperopia and astigmatism. Myopia, also know as nearsightedness is the problem of not being able to see what is far away without glasses. Hyperopia, also known as farsightedness, is the other way round. Astigmatism is something different where the patient has irregularities in his cornea which as a result distorts the image formed on the retina of the eye. After this surgery the need for glasses or contact lens will either be negated, or your dependency on them will be significantly reduced.

But eye operation comes with its own set of risks and they should always be considered seriously before you actually sign-up for an operation. First of all, you will not be eligible for the operation if you are suffering from diabetes, glaucoma, cataracts, arthritis, and lupus. Even pregnant women are not eligible. With these conditions, undergoing surgery can cause permanent damage to your vision.

Other problems that might be caused due to surgery are double vision, glare, and halo. One's nighttime vision can also be affected, especially for certain operation procedures. Even permanent blurry vision and diminished contrast may be the effects of the surgery. We are not trying to imply that surgery is something that involves a lot of risks. All that we are saying is that you should properly educate yourself about the risks also so that you can take a considered decision.

Some patients experience discomfort in the first 24-48 hours after surgery. Other side effects, although rare, may include:

Glare, Seeing halos around images, Difficulty driving at night, Fluctuating vision, Dry eyes. The FDA has found no long-term side effects from laser eye surgery.

Lasik surgery is too new to know if there are any long-term ill effects beyond five years after surgery.

Before the surgery, your surgeon should explain to you the risks and possible complications, and potential side effects, including the pros and cons of having one or both eyes done on the same day. This is the "informed consent" process. If you experience aggravating or unusual side effects, report them to your doctor immediately.
