WHO IS A CANDIDATE?
The majority of nearsighted (myopic) individuals with healthy eyes can benefit from Ortho-K, from children as young as seven years to adults in their 60s-70s.
Will My Prescription Work?
Ortho-K treats myopia (nearsightedness), the condition where distance vision is blurred. Lens powers up to about -5.00 are generally treatable. Astigmatism, a common optical condition where vision is distorted due to uneven curvatures of the eye surfaces, is treatable in low to moderate amounts. Depending on many factors using specialized Ortho-K lenses we often can exceed these levels for many patients with great success. However, sometimes with high astigmatism, we may only be able to achieve "good" vision rather than "terrific" vision. Hyperopia (farsightedness) is treatable but results vary. Not all doctors will treat farsightedness but those who do find a fair amount of success. The results tend to be less predictable.
Can my child have Ortho-K?
Patients as young as seven to nine years old are excellent candidates and we make the decision based on their maturity, hygiene and motivation. These patients are able to play, swim, participate in sports and other healthy activities without the problems of glasses or daytime contact lens wear. Perhaps the most exciting candidate for Ortho-K is the young patient who has become nearsighted for the first time when there is a strong family history of nearsightedness progressing rapidly during childhood. The child whose nearsightedness has been proven to already be progressing is another excellent candidate. There is growing evidence that Ortho-K can slow this progression.
Am I too old for Ortho-K?
Probably not! Patients over forty years old will generally need to consider the fact that near reading vision may be blurred, which happens to everyone with good distance vision as they get older. This condition (presbyopia) can be treated by modifying the power of Ortho-K lenses, wearing reading glasses or other options that can be discussed with Dr. Fenn. Many patients in their sixties and seventies are wearing Ortho-K lenses successfully. What do I do next? The only one who can really tell you if you are a candidate is your eye doctor after they have examined you. We urge you to contact Dr. Fenn's office and schedule an appointment.
