Vision was also improved in the past because the concept of orthokeratology or the practice of reshaping the cornea. The another name of corneal reshaping technology is dream lens. The user who uses corneal reshaping technology that is gas permeable contact lens should wear them during the night or when they are resting. The vision will be improved by the corneal reshaping technology without having refractive surgery. It is expensive to buy improved corneal reshaping lenses.
In the past, there was an attempt to try to improve these cornea reshaping devices but did not work. Computers came to help because better measuring instruments were found. a lot of people have tried to develop the ultimate orthokeratology lens and procedures these days. Several orthokeratology academies that offer a forum and a platform to share ideas and solutions of orthokeratology are many these days. Developments, and workable solutions and technologies are provided by these academies. Paragon corneal refractive therapy is worn by patients during the night because FDA granted an approval for corneal refractive therapy.
The industry in general was able to move rapidly with the development of better and workable solutions for orthokeratology after the approval from FDA. 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. Companies that produce orthokeratology lenses are many out there. Approval of these companies was done by the FDA. The lenses that they produce are gas permeable.
When the approved lenses are used, the health of your eyes will be maintained. Safe lenses are produced by these companies because they use safe materials. Companies that make or design corneal refractive therapy are many. Some complications and side effects are also experienced even if they are used by many people. 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. Also, clean water can be used to wash the lenses also because of the materials used to make them.
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. If the lenses are worn for a prolonged time these problems can also be experienced. Cornea reshaping lenses that are made with materials that are oxygen permeable are the ones you should use. These materials are the best because they reduce hypoxia. Star bursting, ghosting, contract problems and double visions might be experienced by some people. Overly large pupil and lack of centration cause such problems.
