What is Orthokeratology?

Orthokeratology (also known as OrthoK, OK, corneal reshaping, corneal refractive therapy (CRT), and vision shaping treatment) is an alternative method to correct refractive errors using custom-designed rigid contact lenses to temporarily modify the curvature of your cornea. Modern OrthoK technology uses breathable rigid contact lens material and reverse-geometry designs to allow faster and more effective corneal reshaping. Currently, the most common clinical application of OrthoK is for the reduction of myopia through corneal flattening. However, other OrthoK applications can include the correction of nearsightedness, astigmatism and hyperopia). In some cases, ortho-k can also be used to correct presbyopia.

Myopia is now a major public health problem, and high myopia is ranked second as the leading cause of visual impairment globally. Moreover, the onset of visual complications from myopia occurs much earlier than other causes of blindness and thus its impact on quality of life is also seen earlier.

Studies have proven that OrthoK is a safe option for myopia correction and retardation. However, the long-term success of the treatment depends on a combination of multiple factors including proper fitting of the lenses, rigorous compliance to lens use and care regimen, adherence to routine follow-ups, and timely and appropriate treatments to complications.
