Orthokeratology (See Ma’, no Laser)
Wouldn't it be great if your vision could be corrected while you were sleeping? If you answered yes, then please read on. Nearsighted patients can now greatly reduce their dependence on glasses, or eliminate the need to wear them altogether...without surgery! This new development in vision care, approved by the FDA, is called orthokeratology.
Orthokeratology can help reduce or eliminate mild and moderate amounts of nearsightedness (myopia) safely and effectively. Normally, correction of myopia involves reducing the overall focusing power of the eye's optical elements by introducing a "minus" lens in front of the eye. If you are nearsighted, your prescription contains negative numbers (-2.50 D.S., -2.00-1.00x180, etc.) These negative numbers indicate the minus lenses needed to cause light to focus precisely on your retina and give you the clearest vision. Through orthokeratology and corneal reshaping, the curvature of the cornea can be reduced. Reducing the corneal curvature has the same effect as introducing a minus lens in front of the eye.
The cornea is very elastic and can be molded easily. Patients insert the specially designed gas-permeable lenses when they go to bed. During the night, the lenses gently reduce the curvature of their corneas. In the morning, the lenses are removed. Since the corneal curvature has been temporarily reduced, the amount of nearsightedness present has been reduced as well. For the right candidate, vision is improved enough that glasses will not be needed during the day.
Frequently asked questions
Is orthokeratology safe? Corneal reshaping has been approved by the FDA. Over ten years of testing and clinical trials went into the development and manufacture of various therapeutic lenses. The development of these specially designed lenses rose from sophisticated new technologies in computerized corneal mapping and oxygen permeable contact lens materials, making the process both safe and highly effective.
How long does the reshaping process take? Most patients have rapid improvement in the first few days of treatment and have achieved nearly their optimum vision in one to two weeks.
Will I be able to see while wearing the lenses? One of the nice advantages of this procedure is that if you have to get up in the middle of the night, you will be able to see clearly.
Is it reversible? Yes; if you quit wearing the lenses completely, your eyes will return to their original shape. The fact that it is reversible is one of the factors that many people find comforting.
Who is a candidate? With new advancements in this technology, more and more patients are becoming good candidates. During your appointment with Dr. Kamkar, all your options will be discussed.
Orthokeratology offers convenience and puts an end to the need to wear glasses during the day for many patients. Whether you are playing sports, working in a dusty or windy environment, or simply applying makeup, with orthokeratology nothing needs to stand between you and excellent vision. Just wear the special lenses while you are sleeping and take them out in the morning.
To determine if you are a good candidate, schedule an examination appointment with Dr. Kamkar.
