Things You Should Know about Orthokeratology
The concept of orthokeratology (orthok) or the practice of reshaping the cornea to improve vision has been there even in the past. Corneal reshaping technology is also known as dream lens. The use of a gas permeable contact lenses that are worn during the night while the user is sleeping or resting is what is known as corneal reshaping technology. The corneal reshaping technology improves the vision without having refractive surgery. Improved corneal reshaping lenses are not bought at a low price.
There was an attempt to try to improve these cornea reshaping devices but did not work in the past. Computers came to help because better measuring instruments were found. Today, many people have tried to develop the ultimate orthokeratology (ortho-k) lens and procedures. Several orthokeratology academies that offer a forum and a platform to share ideas and solutions of orthokeratology are many these days. These academies also offer developments and workable solutions and technologies. During the night, the patients should wear the paragon corneal refractive that were approved by the FDA.
Better and workable solutions for orthokeratology were developed after the FDA approved the industry, in general, to move forward. When the lenses are worn, cornea will be reshaped when they move around the epithelial cells. Coverage of cornea is done by these cells. However, in some areas, these cells will have to be relocated and compressed. Orthokeratology lenses are produced by many companies. FDA is the one that approved these companies. The lenses that they produce are gas permeable.
The health of your eyes will be maintained when the approved lenses are used. Safe lenses are produced by these companies because they use safe materials. There are many companies that make or design corneal refractive therapy. You will also experience some complications and side effects when you use these lenses. The side effects or complications that are experienced are as a result of improper hygiene. Tap water, when used to wash the lenses, can also experience such side effects. Lenses are made with different materials and thats why some can be washed with clean water.
The patients could suffer from lack of oxygen when they wear them during the night if the lenses are made with wrong materials than the cornea. You will experience some problems when you wear lenses for a long time. You should only use cornea reshaping lenses that are made with materials that are oxygen permeable. Hypoxia is reduced by these materials, and thats why they are the best. Some problems might be suffered by some people like starbursting, ghosting, contract problems, and double visions when they use such lenses. Such problems are experienced by those people because they might lack centration or an overly large pupil.
