Contact Lens Technology


Contact Lens Options for Keratoconus and Other Corneal Disorders

Contact LensThe normal cornea (the front clear lens of the eye) supplies about 75% of the eye's focusing power. In keratoconus, the cornea becomes thinner and loses its structural integrity. As a result, it loses its uniform, domelike configuration and develops irregular astigmatism. It, thus, is unable to produce a clear image inside the eye.

Because the optical surface of the cornea is irregular in keratoconus, glasses cannot give crisp focused vision. Contact lenses, in particular rigid gas permeable contacts (RGP) and a variety of specialty KC and therapeutic contact lenses, can cover these irregularities and better focus incoming light. Applying a rigid lens allows tears to fill the space between the contact lens and the cornea. This layer of fluid optically neutralizes the irregularities of the cornea such that, for all practical purposes, the cornea itself ceases to have any optical effect. The front surface of the contact lens now effectively becomes a new corneal surface... but a surface that we can control, being perfectly smooth, clear, and regular, and also containing the patient's prescription. The contact lens produces a clear image in the eye, often with a dramatic visual improvement for the keratoconus patient.

Contact Lens OptionsAdapting lenses of this type is challenging and rewarding for both doctor and patient. These highly specialized lenses feature a complex series of curves to enable us to fit the lens such that patients may enjoy vast improvements in vision and be able to utilize the lenses throughout their active day. These lenses range from the very tiny (6 mm) to quite large (14 mm).

Hybrid or Synergeyes lenses are sometimes used for proper centration and for sensitive eyes. These lenses have a rigid gas permeable center with a soft skirt around the lens edge. Synergeyes lenses have the advantage of excellent oxygen permeability combined with comfort and availability in a number of configurations for unusual corneal shapes. Recently, we introduced new Synereyes lens designs to our practice, allowing fitting of some previously difficult to fit corneas.  Please go to to read about these hybrid contact lenses. 

Some special cases require a "piggy-back" fitting, an RGP lens fitted over a soft contact lens.  Other patients with KC and other corneal and ocular surface disorders may be helped with scleral and mini-scleral lenses,  which are large, compound curve lenses, which extend beyond the iris onto the white of the eye.

A variety of keratoconus lenses is necessary to fit all the varied shapes and requirements of the keratoconic cornea. Because of this, the CLEI Center for Keratoconus has available every modern technology for the diagnosis and treatment of this disease and a vast specialized KC contact lens inventory (including our own Hersh Palpebral Traction Lens). This gives us the tools to meet the challenge of the keratoconic cornea and restore the patient to useful vision.

Lead by Dr. John D. Gelles, the contact lens division of the CLEI Center for Keratoconus strives to achieve success with even the most difficult KC challenges.  Though not always successful, we will spare no effort in assuring that you get the best result possible.
