Optique Inc Answers Keratoconus FAQ’s
If your vision seems to be getting noticeably worse, you may be concerned about a strange condition you've heard about called keratoconus. Could this corneal problem be the source of your symptoms, and if so, what can you do about it? Here are the answers to some frequently asked keratoconus questions at our Dallas optometry clinic, Optique.
What Is Keratoconus?
Keratoconus is a condition in which the cornea loses its normal, smooth, spherical shape to take on a bulging, cone-like, irregular shape. It typically starts during the teen years, continuing to worsen throughout adulthood.
How Does Keratoconus Affect Vision?
Keratoconus alters the way light enters the eye, interfering with normal refraction and focus of images on the retina. Individuals with keratoconus may experience extreme astigmatism and nearsightedness as a result. Other symptoms include eye discomfort, headaches, poor night vision, and halo patterns around bright lights.
Can Keratoconus Damage the Corneas?
In some cases, the abnormal elongation of the corneas can cause the corneal tissues to swell up and eventually crack. This damage can suddenly make your vision even more blurry than it was before. The cracked tissue may take months to heal.
What Causes Keratoconus?
The causes of keratoconus are somewhat mysterious. It may be that some people ahave naturally weak corneal tissue that has difficulty maintaining its shape. Genetics, oxidative damage, and underlying health problems may all be contributing factors.
How Does Your Dallas Optometrist Diagnose Keratoconus?
Our Dallas optometrist, Dr. Orm, can confirm the presence of keratoconus in a comprehensive eye and vision exam. Refractive testing and corneal measurements can reveal the degree of corneal deformation, while vision testing can help us understand exactly how the condition has affected your eyesight.
What Kinds of Treatment Options Are Available?
Mild to moderate keratoconus can often be compensated for with eyeglasses or contacts. You may need rigid gas permeable contacts such as scleral lenses to get the best results. (Scleral contacts extend over the entire cornea instead of resting directly against it, providing consistent, accurate vision correction even for deformed corneas.) If you need more advanced treatment, we may recommend that you consider a treatmet method called corneal cross-linking, implantable supports called Intacs, or possibly (in the worst cases) even a corneal transplant.
