The Astigmatism Cataract Correction Surgery is a solution of the problem through which the people have to face a lot. Persons are born with astigmatism.
Many times, cataract patients have more than one vision difficulty. These ensure that the patient will need to wear corrective lenses after their successful cataract treatment. For astigmatism, there is a new surgical technique called astigmatism cataract correction surgery. This procedure can correct both cataracts and astigmatism during one surgical procedure and with one lens transplant.
The Astigmatism Cataract Correction Surgery is a solution of the problem through which the people have to face a lot. Persons are born with astigmatism. The clear portion of the surface of the eye — the cornea — is shaped like a cone, rather than a sphere. Vision with astigmatism is quite different from those who are nearsighted or farsighted. People with astigmatism need more light than other people to see well. Much of the light misses the retina because of the abnormal cornea shape. Many people notice most difficulty seeing at night. Streetlights appear to have a “halo” that interferes with vision of objects such as street signs.
Not very long ago, special eyeglasses were the only way to correct astigmatism. Then, special corrective surgery was developed to flatten out the football shape of the cornea and fix the astigmatism to some degree, freeing many from eyeglasses.Now, astigmatism cataract correction surgery is possible. While a patient is having microincision cataract surgery, they can have their astigmatism addressed during the same procedure, although the microincisions are separate from the corneal microincisions.
A special cornea lens transplant addresses both astigmatism and vision after Astigmatism Cataract Correction Surgery. Cataract treatment requires the use of special lenses to replace the cloudy cornea of the cataract. The new lens transplant also corrects the astigmatism. This astigmatism correction surgical technique uses “limbal-relaxing incisions.” These are additional microincisions than are used for the cataracts. As with any surgery, there are some drawbacks and risks.
The astigmatism for any particular patient may not be able to be completely corrected. The results can be unpredictable, under-correcting astigmatism in some cases and over-correcting others. There are some possible surgical risks that the surgeon will address. As with any surgery on the cornea, the corneal structure may be made weaker by the microincisions used in the surgery. If the patient has a subsequent injury to the eye, the cornea may rupture more easily.
With the newly developed lenses, the U.S. Food and Drug Administration found that 97 percent of patients reported freedom from wearing glasses for distance vision, but many still required glasses for close work. It is important to note that astigmatism cataract correction surgery and the special lenses are usually not covered by medical insurance. A qualified eye surgeon should evaluate each patient for suitability for this procedure and will discuss the options.
