Refractive eye surgery is any eye surgery to improve the refractive state of the eye and decrease dependency on glasses or contact lenses. Most common methods today use lasers to reshape the cornea. Successful refractive eye surgery can help to reduce such common vision disorders as myopia, hyperopia, astigmatism, and presbyopia.
Myopia, also known as nearsightedness, is the result of an eyeball which is too long, or a cornea which is too curved. In both cases, light rays entering your eye fall short of the retina, and objects in the distance appear blurred.
Hyperopia, also known as farsightedness, is a defect of vision when the eyeball is too short or when the lens cannot become round enough. This causes the inability to focus on near objects and in extreme cases causes a sufferer to be unable to focus on objects at any distance. As an object moves towards the eye, the eye must increase its power to keep the image on the retina.
Astigmatism occurs when your cornea is shaped like a football with two different curvatures. Images appear blurred or ghost-like because light rays are refracted unequally. In extreme cases, images both near and far, appear blurred.
Presbyopia affects almost everybody in their 40s. Current refractive surgery, including PRK and LASIK, does not cure it. Presbyopia refers to the eyes’ diminishing ability to focus up close with age. For patients in their 20’s and 30’s, presbyopia is often difficult to understand. If this applies to you, one of the best ways to understand presbyopia is when your eyes are dilated at your eye care provider’s office. The dilating drops simulate presbyopia by relaxing your eyes’ ability to focus (besides making your pupils large). If you wear glasses to see clearly far away, put them on when your eyes are dilated. Then try reading. It’ll be hard to focus, and this is what presbyopia is like!
The physicians at ITEC have been in practice over 34 years and have been doing refractive surgery in Montgomery since the early 1980's. They were also the first surgeons in Montgomery to perform Excimer laser surgery in their office. ITEC surgeons are now able to do refractive surgery for patients who have myopia and astigmatism as well as patients who have hyperopia.
ITEC offers free one on one consultation for patients to learn more general information about refractive surgery. During the more extensive consultation, the available options and the benefits of refractive surgery are explained. Possible complications will also be explained. The patient's refractive error is discussed in detail and the patient will be advised regarding their visual potential without glasses. All questions will be answered.
