Astigmatism Treatment From Eye Doctors Of Arizona
People who are nearsighted don't have a clear focus on objects that are far away. People who are farsighted don't have a clear focus on objects that are up close. And people who have astigmatism don't have a clear focus on objects at any distance. Glasses and contact lenses can help, but sometimes what people need for correction of astigmatism is intervention by their ophthalmologist, not just new lenses from their optometrist. Eye Doctors of Arizona has three convenient locations in Phoenix with both kinds of practitioners to provide you with optimum care. Here is what our ophthalmologist and eye doctors want you to know about astigmatism.
People with nearsightedness or farsightedness often also have astigmatism
Astigmatism results when the eyeball is not perfectly round and many of us were born with eyeballs that are not perfectly round. In astigmatism, the eye is shaped more like a football and less like a basketball. Astigmatism can get worse throughout childhood if it is not detected and corrected early on. Astigmatism can also develop following an eye injury or eye surgery.
Children who have astigmatism struggle in school
Children who have astigmatism, like children who are nearsightedness, can't really see what is going on in their classrooms. Without corrective lenses, they will have more and more trouble keeping up. But grades and reading scores often go up once children receive the corrective lenses they need if they wear them all the time.
Diagnosing astigmatism isn't just a matter of reading letters on a chart
We are all familiar with the eye charts that help your eye doctor discern whether you may be nearsighted or farsighted. But checking you for astigmatism requires two additional tests. The eye doctor will use an instrument called a keratometer to measure the surface of your cornea. This is essential for determining the fit of contact lenses, should you and your doctor decide you should wear them. And your eye doctor will use an instrument called a phoropter to put a series of lenses in front of your eyes to see which help you best see light.
Astigmatism is treatable with corrective lenses
Most cases of astigmatism are treated with glasses or contact lenses. Sometimes children are treated with corrective contact lenses worn at night to reshape the cornea. This procedure is known as orthokeratology or ortho-k.
Sometimes your ophthalmologist can treat astigmatism surgically
The advantage of an eye center that can offer you the attention of both an optometrist and an ophthalmologist is that sometimes conditions like astigmatism are treatable with LASIK (laser in situ keratomileuses) or PRK (photorefractive keratectomy). These procedures are done in the doctor's office and only take a few minutes. Sometimes they offer a permanent cure.
