Orthokeratology

Ortho-K, CRT or "Night contact": 100% of our patients achieved 20/25 vision or better and 90% percent achieved 20/20 or better.

Ortho-K is a non-surgical process, which reshapes (flattens) the cornea of the eye using contact lenses to reduce refractive errors (nearsightedness and astigmatism). Accelerated Ortho-K uses reverse geometry contact lenses. Flattening the cornea reduces the focusing power of the eye. Since the amount of corneal flattening can be accurately controlled, it is possible to bring the eye into correct focus and compensate for the refractive error. 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 day to maintain the corneal flattening, or the myopia will revert to the pre-treatment level.

Children and adults can be treated with Ortho-K because the principle of flattening the cornea is effective for both. Myopia control is used to slow or stop the increase in axial length of the eye that occurs in growing children who are becoming more nearsighted each year. This may result in a lower prescription, so the child won't have to wear the thick lenses he might otherwise require by the time he/she is a teenager.
