Astigmatism Correction Is Measured In Degrees
Astigmatism correction is possible with a prescription for eyeglasses, contact lens, or refractive surgery. One form of refractive surgery is PRK, also known as photorefractive keratectomy, which uses a laser to correct the degree of curvature that the cornea is away from being spherical, rather than the usual oblong shaped cornea common to most of those who suffer with astigmatism.
Before you are considered for surgery, your eye care provider will run a test, or several tests, to determine what the degrees of mytopia, hyperopia, and astigmatism.are Mytopia, hyperopia, and astigmatism are types of measurements that in combination define the condition of your eye and curvature of the cornea. What this means is he will test to see how bad your sight really is. Surgery is a sensitive matter and not right for everyone. In the case of astigmatism, the highest success rate comes to those with a mild to medium case of stigmatism. Without taking the time to collect the proper information, the surgeon cannot make the correct incisions necessary to improve your vision.
Fortunately, if you qualify for the surgery, photorefractive keratectomy has a high success rate, and scientists are looking for even better answers for those who suffer from blurred vision. And even more importantly, the procedure is safer than ever before.
For those whose astigmatism is beyond successful laser surgery reach, there is hope. Toric contact lenses are design especially with your problem in mind and those too are improving with additional research. And, of course, eyeglasses are always a viable option.
