There are a few occasions where contact lenses are used to treat an eye health problem. One of the more common conditions is known as keratoconus. Keratoconus is a condition which causes the front surface of the eye (cornea) to become progressively thinner with age. The result, of this thinning, is a distortion of the cornea causing a dramatic increase in astigmatism.
Glasses may correct it in the earlier stages, but most patients only achieve good vision with a rigid gas permeable contact lens. These are typically more complex rigid lenses, than the traditional type and patients, with this condition, are carefully fitted and monitored more closely than the average patient. As the condition progresses the lenses will have to be modified to continue to achieve good vision and eye health.
Dr. Furniss is very experienced in fitting keratoconic lenses.
