If you are looking for an alternative to laser surgery that can improve your vision in a similar fashion, you may be interested in orthokeratology, or more commonly known as “ortho-k”. Ortho-K involves temporarily reshaping the cornea through the use of specialized contact lenses. Although these lenses are not very common and most people still prefer laser surgery to ortho-k, the reshaping method gained more attention and approval after the contact lenses were designed to be worn while sleeping.
