About Ortho-K

Orthokeratology is a process that uses custom designed gas permeable contact lenses to temporarily reshape the contour of the cornea to reduce myopia (nearsightedness) and other vision problems. Patients that use orthokeratology lenses report a high level of satisfaction because glasses and contact lenses aren't needed during waking hours.  In addition to the benefit of lens-free daytime vision, orthokeratology is appreciated for its ability to slow the progression of myopia. A number of published clinical studies have found that orthokeratology lens designs inhibit lengthening of the eye, which slows the progression of nearsightedness.
