We have all heard the terms nearsightedness, farsightedness, and astigmatism, but few people have actually taken the time to understand them. To appreciate Orthokeratology it is important to become familiar with the principles involved in these refractive errors.
What has been done in the past, and is still being done, is to pre-focus the light rays by eyeglasses and conventional contact lenses. In most cases, this adequately solves the problem of blurred vision and eyestrain. What it does not do is attack the CAUSE of the problem. Is there any way to get to the source of the problem? YES, there is.
Contact lenses became popular because of a desire to get away from cumbersome eyeglasses, mostly for cosmetic reasons. As the practice developed, it was found that there was less distortion with contact lenses, they were a more natural way of seeing and did the job better.
As the contact lens field grew, researchers began to study the side effects of wearing contact lenses. What they discovered was that in many cases the refractive error was actually decreasing in small amounts. Further studies showed that there was a direct relationship between these improvements and the corneal curvature changes. Armed with this new information, practitioners were able to attack the actual cause of the problem for the first time.
Obviously, there is nothing that can be done with the length of the eyeball. The only option is to concentrate on the cornea and its curvature. This is the basis of Orthokeratology. Simply stated, the purpose of Orthokeratology is to permanently alter the curvature of the cornea so that no external devices are necessary for good vision.
Through research and experimentation, Orthokeratologists have found that the cornea is a soft, pliable, yet very tough tissue. It will maintain its integrity and respond to changes imposed upon it by contact lenses that are specially designed for that purpose.
Dr. Garber, one of the leading Orthokeratologists, has developed a proprietary DRUG-FREE procedure that utilizes specialized computers and equipment to map out the EXACT curvature of an individual’s eye. With this information a special contact lens can be created for each individual eye to correct the exact refractive error of that eye for a custom fit and maximum correction. Lenses are worn overnight and removed in the morning. This gives the eye good vision all day long!
