Types of Astigmatism

When your eye works properly, the cornea bends light and focuses it onto the back of your eye, also known as the retina. However, many of Dr. Vic Khemsara’s Winston-area patients suffer from an irregularly shaped cornea. When the cornea has significant imperfections, you don’t see right: your vision is out of focus, and you usually have distorted vision. This corneal imperfection if called astigmatism.
A comprehensive eye exam can diagnose your astigmatism, but before seeing Dr. Khemsara about your vision issues, some information on astigmatism could prove useful. The more you know, the more comfortable you will be. One thing to understand is that are multiple types of astigmatism.
Every eye is different, and every vision problem is unique. Most corneas have some mild, unimportant imperfections. Dr. Khemsara will be able to thoroughly evaluate your eyes and detect any significant corneal imperfections.
There are two main types of astigmatism.
• Regular: In a regular astigmatism, the cornea is oblong, or football-shaped, when it should be a sphere.
• Irregular: In the irregular astigmatism, the problem is not so much the shape of the cornea as it is the imperfections of it. A cornea with numerous bumps and waves will reflect light unevenly, thus proving poor vision.
Dr. Khemsara has many options for the treatment of astigmatism. Your treatment options will depend on your type of astigmatism.
If you suffer from a regular astigmatism, you have a wide range of choices, including eye glasses, hard or soft contact lenses and LASIK vision correction surgery.
For those with irregular astigmatism, your main choice will be between hard contact lenses and vision correction surgery. Eyeglasses won’t help.
