Lasik eye surgery is the process of reshaping the cornea – or the eye’s front surface, containing its lens – to correct errors in vision. This makes it a sound treatment option for one of the world’s most common eye problems: astigmatism.
What is astigmatism?
Astigmatism refers to the condition when a person’s cornea is asymmetrical. Normally, the cornea should be perfectly round; in people with astigmatism, it is more oval, like a football, egg, or the back of a spoon. The unevenness of the cornea causes light to enter the eye unevenly, leading to blurred or distorted vision.
How can lasik help?
Eyeglasses and contact lenses can typically and effectively treat astigmatism, but may come up short against irregular and advanced forms of the condition. At best, these help a person see clearly despite astigmatism.
Lasik treatments can help a person see clearly because it can remove the root of astigmatism. In altering the shape of the cornea, this treatment can make it more symmetrical, improving the way light enters the eye, and eliminating the problem altogether.
One more factor in favor
Aside from this reason, there may be one more reason why surgery could be an apt solution to astigmatism. According to the American Academy of Ophthalmology, most people with astigmatism inherit the condition. They do not acquire or develop it by reading in low light or moving vehicles, or by overexposure to television and computer screens. If there is no chance for the condition to improve naturally, then it might be best to address its cause conclusively.
However, only your doctor can determine if lasik eye surgery is indeed the best way to treat your astigmatism.
