Frequently Asked Question about Keratoconus at
Richardson Eye Associates
Individuals who suffer from keratoconus can experience serious visual blurring and distortion that grows worse as the condition progresses. The more you understand about this condition, the more confidently you can pursue treatment for it. Take a look at these frequently asked questions about keratoconus from Richardson Eye Associates in Richardson, TX.
What Is Keratoconus?
Keratoconus gets its name from the cone-like shape assumed by corneas affected by this condition. In this condition, the corneas lose their normally spherical shape in favor of an increasing outward conical bulge. This deformation alters the way incoming light enters the eye, resulting in blurry vision.
How Does Keratoconus Affect Eyesight?
The corneal bulge created by keratoconus effectively lengthens the eye, causing myopia. The abnormal curvature of the cornea also produces astigmatism. If the cornea experiences too much structural stress, it may develop cracking and swelling that blurs vision further.
Why Does Keratoconus Occur?
Keratoconus is caused by weakness in the collagen fibers that normally support an even, smooth corneal curvature. Low antioxidant levels may allow for further damage to be done to the eye. A family history of keratoconus can also raise your risk of developing the problem.
How Do Eye Doctors Treat Keratoconus?
Eye doctors can easily detect keratoconus by examining a person's corneas during a comprehensive eye exam, using vision testing to determine just how severely the condition has affected your eyesight. Depending on the findings made during testing, you may receive a recommendation for corrective lenses or for more advanced treatment methods, such as Intacs (inserts that support the corneas). We may also refer you for a procedure known as corneal cross-linking, another technique for strengthening the corneal tissues to prevent progressive keratoconus symptoms.
What Kinds of Corrective Lenses Help with Keratoconus?
Eyeglasses and soft contacts may correct mild keratoconus adequately. However, once the condition progresses, you will probably need specialized contact lenses. These lenses may combine rigid and soft technologies, such as hybrid or "piggyback" lenses. Scleral contacts can prove even more effective due to their ability to span the entire curve of the cornea, compensating for bulges and other irregularities with great accuracy.
