When these lenses are taken out in the morning, the change in corneal curvature effectively corrects your vision and allows freedom from glasses during the day. The effect generally lasts the entire day and lenses are worn every night to maintain clear daytime vision. These lenses can be used at any age to allow freedom from glasses, but the most common clinical application of OrthoK is in children. These lenses are designed to reduce myopia (nearsightedness), effectively slowing down elongation of the eye. You can read more about myopia control in Calgary.
Our optometrists at Mission Eye Care in Calgary are skilled and passionate about myopia control and are proud to be the only clinic in Alberta with 2 eye doctors residency trained in specialty contact lens fitting. They have extensive research backgrounds and clinical experience in the area of corneal reshaping and myopia management. There is no age limit on who can wear orthokeratology lenses, but we generally start as soon as myopia changes are noted, often as early as age 7. When used as directed and fit by an experienced optometrist, OrthoK is a safe and effective option for refractive error correction and slowing of myopic progression.
