The practice of Orthokeratology also known as vision correction by means of corneal reshaping, has been around for a number of years already. However, there are only a few of these lenses that were approved by the US Food and Drugs Administration (FDA).
How Can We Benefit from Orthokeratology?
Further studies in Orthokeratology have resulted to the advancement towards the treatment of myopia and slowed down the myopic progression. Several studies were also conducted on some countries outside the United States to further validate this technology. However, as of now, there are no new designs for Orthokeratology contact lenses that were approved by FDA, but researches are still continuously being conducted to improve this new vision of eye correction technology.
What Is Orthokeratology?
Basically, Orthokeratology is a vision correction technology that is done by means of reshaping the cornea. Studies show that the epithelial cells that are on the corneal surface are either compressed or relocated by means of this technology and vision correction of up to -6.00D are made possible through this. However, there are several side effects that have been found to result from using these implements, and one of the side effects could even result to blindness. Some experts would attribute such Orthokeratology side effects to the patient’s failure to strictly follow the proper instructions and precautions in using these lenses. They even stress that hygiene is the number reason for blindness, which is one of the Orthokeratology side effects.
Another cause for Orthokeratology side effects is the use of wrong materials in manufacturing the contact lens. Corneal hypoxia, a term used to refer to the lack of oxygen in the eyes is often experienced when using a non-oxygen permeable material for contact lenses that are for overnight-use.
So before you decide to use any orthokeratology implement, make sure to consult with your eye doctor to avoid any problems.
