Blur due to Irregular Cornea
Refractive surgery, corneal transplants, infections and corneal syndromes like Keratoconus are among the many potential causes for irregular corneas. An irregular cornea results in symptoms of blur and distortion that glasses and most contact lenses are unable to correct. Visual symptoms from an irregular cornea are constant, but often worsen in dim light when the pupil is more dilated.
In the past, some of these individuals were fit with rigid gas-permeable (RGP) contact lenses. RGP lenses do not conform to the shape of the eye like a soft lens does. Instead the RGP’s rigid structure allows tears to fill in behind the lens and create an optically smooth surface for light to enter the eye and provide improved vision. Unfortunately, RGP lenses are too uncomfortable for most patients, are easily lost, and can cause scarring to the front surface of the eye.
ClearKone Lens Design
ClearKone is a new hybrid contact lens product that has both the comfort of a soft lens combined with the acuity benefits of a rigid lens. ClearKone is an improvement upon other similar hybrid products because its unique design is more comfortable and easier to remove than older hybrid lenses.
Special expertise is required to fit the ClearKone lens. Currently, Dr. Ryan Nelson, optometrist at Iowa EyeCare in Cedar Rapids, is the only physician in Iowa approved fit ClearKone lenses. Dr. Nelson gives each ClearKone candidate extensive one-on-one time during the fitting process to ensure a good contact lens fit the first time.
“The ClearKone design is sure to revolutionize the way patients with irregular corneas are managed. Some of my patients have been overwhelmed with emotion when they experience the ClearKone lens for the first time,” says Dr. Nelson.
