Brief
Course Description

Orthokeratology is a temporary correction of myopia and astigmatism using specially designed rigid contact lenses
to flatten the central cornea. The effect is similar to that of refractive surgery: by flattening the cornea, the
refractive power of the eye is reduced, which makes the eye less myopic. This procedure has also been known by a
variety of terms, such as Orthofocus, Precision Optical Molding, Controlled Keratoreformation, Corneal Refractive
Therapy, and Vision Shaping Treatment, among others. Ortho-k is still the most widely used term and will likely
remain so.
