Next Gen Contact Lenses During Night Only
The concept of OrthoKeratology dates back to ancient China where it was discovered that sleeping with small bags of sand on your eyes improved your vision the following day.
OrthoKeratology (Ortho-K) is a non-surgical process which reshapes (flattens) the cornea of the eye using custom made contact lenses during the night to reduce refractive errors (nearsightedness and astigmatism). The patient would take the lenses out in the morning and they are able to see the rest of the day without any glasses or contact lenses.
Accelerated Ortho-K uses reverse geometry contact lenses. Flattening the cornea reduces the focusing power of the eye. If the amount of corneal flattening is accurately controlled, it is possible to bring the eye into correct focus and compensate for myopia (nearsightedness). After the contact lens is removed, the cornea retains its flattened shape for part or all of the remainder of the day. A retainer lens must be used each night to maintain the corneal flattening, or the myopia will revert to the pre-treatment level. Ortho-K is also successful for some degrees of farsightness by steepening the central cornea.
