Keratoconus – An Abnormal Disease of the Cornea

Keratoconus, which is pronounced (KEHR-ah-toh-KOH-nus), is an uncommon eye condition where the typically round, oval-like cornea becomes thin and develops a cone-like bulge. Keratoconus literally means “cone-shaped cornea.”  The cornea is the clear, front part of the eye. The cornea actually expands outward and the cornea becomes extremely steep. It is very common that keratoconus affects both eyes of an individual, however symptoms will vary from patient to patient. The cause of keratoconus is still not known. Some researchers believe that genetics play a role, since an estimated 10% of people with keratoconus also have a family member with the condition.

The cornea is a very crucial part of your eye and has a lot to do with how you actually see. As light enters the eye, it refracts, or focuses, the light rays so that you can see clearly. With keratoconus, the shape of the cornea is altered, distorting your vision. Keratoconus can make many activities difficult, such as skiing, driving, typing on a computer, watching television. Some basic activities just become overwhelmingly difficult for a keratoconus patient.

NOTE: Patients with keratoconus are typically not good candidates for LASIK eye surgery. With the assistance of Corneal Associates, New Jersey's corneal specialists and ophthalmologists, a patient with keratoconus can receive state of the art treatment modalities. Our cornea specialists are fellowship trained specifically to treat this special eye condition. You may rest assured that your eyes are in the best of hands with New Jersey's Corneal Associates.

 Symptoms of Keratoconus (symptoms may vary)

Keratoconus is routinely problematic in both eyes, however; symptoms in each eye may differ. It is a myth that keratoconus only affects older people or seniors with vision problems. Keratoconus can affect persons of all ages but typically starts to develop by the mid – late teen years. The rate of keratoconus progression varies. It will often progress slowly for 10 to 20 years and then suddenly stop. As the condition progresses, the most common symptoms include:

• distortion of vision
• sensitivity to light
• glare
• slight irritation
• mild blurring of vision

Keratoconus Treatment

Treatment will often depend on the severity of the condition. During early stages, vision can be corrected with eyeglasses. As the condition progresses, rigid contacts may need to be worn so that light entering the eye is refracted evenly and vision is not distorted. You should refrain from rubbing your eyes, as this can aggravate the thin corneal tissue and make symptoms worse.

When good vision is no longer possible with contact lenses or Intacs, a corneal transplant may be recommended. This surgery is only necessary in about 10-20% of patients with keratoconus. During corneal transplantation, your cornea specialist removes the diseased cornea from your eye and replaces it with a healthy donor cornea.

While a corneal transplant will relieve the symptoms of keratoconus, it may not provide you with flawless vision; eyeglasses or contacts may still be needed to achieve your best vision.

Keratoconus and Laser Vision Correction

Due to the irregular shape of corneas that have keratoconus, LASIK or laser vision correction is often ruled out. The Orbscan diagnostic device can determine the steepness of your cornea through a simple eye test and a topographic map of your eye can be measured. If you are a patient that has developed keratoconus and you would like to experience the same lifestyle benefits that LASIK has brought millions of people, please make sure to discuss this desire with Dr. Perl. Recent advancements may make you a candidate for a different type of refractive surgery.  Dr. Perl currently uses the Phakic Lens Implants for patients with high to moderate levels of myopia.

If you are an existing keratoconus patient and require the professional consultation of a cornea specialist please feel free to contact our practice. Dr. Perl has dedicated his ophthalmology focus to understanding the cornea and diseases of the cornea.
