Modern Orthokeratology (ortho-k) is a scientifically validated, FDA-approved method of correcting low to moderate myopic refractive errors—up to -4.00D, and in some instances, up to -8.00D. The design of ortho-k lenses has evolved to include treatment for astigmatism and low degrees of hypermetropia and presbyopia.
With the use of specially designed and fitted contact lens, ortho-k can temporarily reshape the cornea to improve vision. It’s like orthodontics for your eyes and the treatment is often compared to dental braces. Most ortho-k lenses are worn at night to reshape the front surface of the eye while you sleep, allowing your child to see clearly the next day without any lens.
We are also seeing strong indicators that ortho-k can play an important role in myopia control. Studies have found that ortho-k reduces the lengthening of the eyeball (a key factor in myopia progression) by 43% in children when compared with similar children who only wore regular eyeglasses for myopia correction.
