Astigmatism LASIK surgery is a procedure that not a lot of people may be aware of since they believe that LASIK can only treat myopia or nearsightedness. Astigmatism is a condition that occurs when the cornea is egg-shaped, resulting in multiple focal points and slightly distorted images. However, if the degree of astigmatism is high enough, it can result in blurred vision at both near and far distances.
Like the procedure for myopia, astigmatism LASIK surgery is conducted on the cornea. A flap is created on the surface to allow access to the inner corneal tissue. This is then reshaped by a laser to effect vision correction. In the case of astigmatism, the cornea is flattened on one axis rather than the other.
LASIK surgery for Astigmatism has been shown to be effective in treating people with mild to moderate cases of astigmatism, giving them vision good enough that they no longer need to wear glasses. This allows them to participate in sports activities where wearing glasses may be a hindrance.
However, astigmatism LASIK operation may not be the appropriate choice for all people with the condition. You will have to consult with the eye doctor as to whether or not you are an appropriate candidate for LASIK. He will perform a screening or pre-evaluation that will determine if LASIK can help you which includes assessing the thickness of your cornea. In addition you will also be tested for other conditions in addition to your astigmatism, such as keratoconus (a degenerative eye condition that causes the cornea to become more conical) which will not be helped by LASIK. During this pre-screening you should inform your doctors all the medications that you are taking and address health conditions such as hypertension.
One of the most important things to remember about LASIK surgery to treat astigmatism is that you should keep your expectations realistic about the results that you get. While the majority of patients achieve results that are good enough to allow them to drive, depending on their particular physical condition, results may vary. In addition, there is always the possibility of complications that might affect the outcome of the operation and may even threaten vision. This is why you should always talk over in detail the astigmatism LASIK surgery procedure with the eye doctor so that you will be fully informed about the risks and benefits, as well as the limitations of the LASIK procedure.
