What You Need to Know About Keratoconus
Keratoconus is part of a family of disorders involving abnormalities in the shape of the cornea, the clear front of the eye. Affecting millions, keratoconus is characterized by an abnormally steep and irregularly shaped cornea, which makes vision blurry.
How do I know if I have Keratoconus?
Visual changes from keratoconus are occasionally mild, but severe disease may cause thinning and scarring along the visual axis. The symptoms of keratoconus vary with the degree of thinning, astigmatism, and scarring.
Light sensitivity, sudden pain, and corneal swelling are all common in severe keratoconus. It is important to note that each eye can be affected differently and may stabilize after some time.
If you are experiencing any of these symptoms, it is important to visit your eye doctor for a complete visual exam.
If you have concerns about keratoconus, please Contact Dr. Harvey.
What can be done to treat Keratoconus?
Early on in Keratoconus, patients typically have astigmatism correctable with glasses or soft contacts. As the disease progresses, gas permeable or newer hybrid (e.g. Synergeyes) contact lenses may be needed to obtain the best vision.
If contact lenses cannot adequately compensate for the abnormal Keratoconus hsape, collagen crosslinking may be considered. This cornea strengthening procedure is the only means to stop progressive bulging in certain corneas. If crosslinking is not possible, cornea transplants are sometimes recommended.
Full-thickness and partial-thickness cornea transplants have been time-tested remedies for keratoconus. By replacing the steep cornea with a sutured donor cornea, a relatively normal curvature can be restored. Astigmatism reducing therapies, such as corneal inserts (Intacs®), have helped many Keratoconus patients find greater comfort in contact lenses and avoid a transplant.
If you are experiencing any of these symptoms, or have additional questions about your eye condition you should contact an Ophthalmologist.
