Orthokeratology Contact Lenses

Correcting corneal vision iIlnesses has been researched in the earlier twentieth century. Earlier, experts had come up with glasses that could treat them. The development of Orthokeratology originated in 21st century with the so called Orthofus developed by George Jessen. The earliest Orthofus contact lenses were made of hard polymethyl methacrylate. There were variants of Orthokeratology contact lenses made during the earlier
s. But, the latest designs have set up with the most best advancement ever. The latest Orthokeratology contact lenses are identified as super gas permeable and could be put on during sleep

Further improvements and development of Orthokeratology contact lenses were attributed to a series of great Orthokeratologists. Newly developed Orthokeratology contact lenses are made of rigid gas permeable lenses which are known as super gas permeable. These contact lenses are made from specific kind of firm plastic that allows great amount of oxygen to get through the cornea .Oxygen permeability is very important throughout the treatment of corneal vision problems. Ortho-k contact lenses are larger than the standard ones and fabricated with multi-curves by using a computerized machine known as Great Molding. Modern designs have developed the most comfy contact lenses to date. Contact lenses are known to be considered used during waking hours could now be worn during sleep. These sleep-worn Ortho-k contact lenses are worn during the long sleep hours and taken off during waking hours. Ortho-k contact lenses can appropriately reshape the curvature of cornea. The formation of Orthokeratology contact lenses are flawlessly devised for not touching the surface of the cornea. Their unique reverse geometrical curve formation compresses and appropriately shifts epithelial cells in the cornea. As the cornea's surface is reformed, it could then correctly refract light to the retina for better vision.

Orthokeratologists greatly trust the capability of Orthokeratology contact lenses to correct corneal-related eyesight problems such as myopia, hyperopia and astigmatism. Astigmatism is characterized by distorted eyesight with both close and far objects. Nearsightedness or myopia is characterized by failure of seeing objects in even farther distance. The complete opposite of myopia is hyperopia or better known as farsightedness, it's known as the ability of seeing further objects but disability of viewing nearer ones. These corneal problems are caused by a steep-shaped cornea or elongated eyes caused by excessive or dislocated epithelial cells. Corneal problems could be caused by abusive usage of the eye or visual stress. Other aspect of it could be hereditary. Infants, children and adult could have these problems. Up to -6 diopters of myopia and 1.75 diopters of astigmatism could be corrected by these contact lenses. There are many methods applied to diagnose these vision problem but the recent one is called corneal topographer. By this instrument, Orthokeratologist could figure out the degree of the condition based on the color coded map produced by the device. Prescription comprises the type of lenses to be worn, wear schedule and period of treatment. Treatment using Orthokeratology contact lenses won't last for a year.

Orthokeratology contact lenses are more advantageous than ever. Other than addressing eyesight problems, these contact lenses are advantageous for those users who are not at ease using contact lenses or glasses throughout the day. It is even more advantageous to pilots, athletes, soldiers and more. With the recent advancement of Orthokeratology contact lens, there would be a great chance that it could replace the traditional use of corrective spectacles and surgical method in reshaping the cornea.
