Ortho-K

ORTHO-K

Orthokeratology, or Ortho-K, is a type of contact lens designed to reshape the cornea overnight, providing temporary vision correction and potentially slowing the progression of myopia (nearsightedness).
Ortho-K lenses are worn during sleep and work by gently flattening the center of the cornea, reducing its refractive power and improving vision. The effects of Ortho-K lenses typically last for one to two days, and the lenses must be worn nightly to maintain the effect.
Ortho-K is important for myopia control because it can slow the progression of myopia in children and young adults, potentially reducing their risk of developing more severe myopia and associated eye conditions later in life, such as cataracts, glaucoma, and retinal detachment.
By reshaping the cornea, Ortho-K can also provide an alternative to traditional corrective lenses, such as glasses or contact lenses, for those who may not be suitable candidates for refractive surgery.
Overall, Ortho-K is a non-surgical, reversible option for temporary vision correction and myopia control, offering potential benefits for those with mild to moderate myopia.
