The Benefits Of Wearing Orthokeratology

Orthokeratology, rigid gas-permeable contact lenses

, is usually worn during the night to enhance or improve eyesight or vision by reshaping one's cornea. Instead of wearing contact lenses or eyeglasses every day or even undergoing refractive surgery, its a good method to achieve a clear vision enough to perform your responsibilities by day.

Actually eye doctors discovered the reshaping of the cornea eye treatment by using glass lenses during the 1940s. The early designs of ortho-k exhibited irregular and unpredictable outcomes, which made people think it not so effective. But now with the development of computers and measuring instruments special overnight lenses theory in reshaping the cornea has created new designs presenting effective and repeatable results.

Most people think that the special overnight lenses utilized in ortho-k reshape the eye's cornea by budging the epithelial cells that envelop the cornea's surface. Several studies show that the epithelial cells pack together in some regions and may also be repositioned. One of the usual misconceptions in the special overnight lenses design is that they force down on the cornea and eventually flatten the eye. In fact, the idea that the compelling forces produced by the reverse curve result to redistribute epithelial cells but not pressure on the eyes. An appropriate design of lenses should not be in contact with the patient's cornea.

Orthokeratology lenses are being manufactured by many companies through the facilitation of one of two Food and Drugs Administration's (FDA) approved technologies, all of which make use of special gas-permeable eye lenses to reshape the cornea. The material which lenses are made of is an important factor to keep the eye's condition and health during the treatment period.

There is one thing important that only few brands of ortho-k special lenses have been authorized by the FDA to be worn safely overnight. Eye doctors may devise the shape of the lens using the principles of ortho-k. Different systems and software packages make it possible, which help design the lenses while creating the appropriate changes on the eye.

There are some side-effects like blinding complication though many people have been taking advantage of this eye treatment especially those with Myopia or nearsightedness. Most of the time, it would happen when patients fail to strictly follow the use of tap water when rinsing and doing proper hygiene, or because of lack of oxygen in the eye or relative corneal hypoxia brought about by use for a very long time or the lenses made from wrong or inappropriate materials.

Its important to make sure lenses are made from high oxygen-permeable materials when using orthokeratology, which can lessen hypoxia and prevent users from experiencing other side effects due to overly huge pupil size such as double vision, ghosting, star bursting and contrast quandaries particularly during night time.
