MANAGEMENT OF EARLY KERATOCONUS

Management of Early Keratoconus

Keratoconus, meaning "cone shaped," describes a condition in which the cornea (the clear front window of the eye) becomes thin and protrudes. This abnormal shape can cause serious distortion of visual images.

The cause of keratoconus is unknown. It usually appears in a patient during their late teens or early twenties. The disease slowly progresses for 10 to 20 years as the cornea steepens and scars. Although both eyes may be affected, one eye is usually worse than the other.

Vigorous eye rubbing can add to the disease process, therefore patients with keratoconus are advised to avoid rubbing their eyes.

Symptoms
  • Frequent changing of glasses or contact lens prescriptions
  • Blurring and distortion of vision
  • Glare
  • Light sensitivity and irritation
  • Scarring of the cornea

The symptoms described above may not necessarily mean that you have keratoconus. However, if you experience one or more of these symptoms, contact your eye doctor for a complete exam.

TREATMENT OPTIONS

The treatment approach to keratoconus follows an orderly progression from glasses to contact lenses to corneal transplantation.   Glasses are an effective means of correction mild keratoconus.  As the cornea steepens and becomes more irregular, glasses are no longer capable of providing adequate visual improvement.  Corneal transplant surgery is indicated when a patient cannot wear contact lenses for an acceptable period of time or when the vision, even with contacts, is unsatisfactory.

A gas permeable contact lens is the most highly effective way to manage keratoconus and 90% of all cases can be managed this way indefinitely. If the cornea becomes too scarred or painful, a corneal transplant may be necessary.

Spectacles

Mild keratoconus can be corrected with spectacles. Retinoscopy is difficult; a normal subjective refraction is required. Monocular keratoconus is usually best dealt with using spectacle correction. In this group of patients, motivation for contact lens wear tends to be poor.

CONTACT LENSES

The use of gas permeable contact lenses has been the mainstay of the optical management of keratoconus.  These lenses, manufactured in a large variety of unique designs, provide a regular surface over the cornea to neutralize the distortion brought on by the irregular cornea.  No one design is best for every type of keratoconus. Since each lens design has its own unique characteristics, the practitioner needs to carefully evaluates the needs of the individual and find the lens that offers the best combination of visual acuity, comfort and corneal health.
Rigid lens fitting in keratoconic eyes is however, by no means simple.  Numerous lenses are often required, fitting a keratoconic eye is an art as much as a science.
