    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.
