What is orthokeratology?

photo-familyOrthokeratology is a safe, non-surgical method of providing clear, comfortable daytime vision without wearing glasses or contact lenses. This is achieved through the use of specially designed rigid contact lenses worn overnight that reshape the cornea.

Upon awakening the lens is removed, and the new shape of the eye allows for clear vision throughout the day. This is a temporary and reversible effect, so retainer lenses must be worn overnight to maintain the effect.

With orthokeratology our goal is to provide you with 20/20 vision without your contact lenses or glasses. With the appropriate lenses, improved vision is usually experienced after the first overnight wear. Due to the reversible nature of this treatment, during the first few days vision may not remain clear the entire day. The correction typically stabilizes after approximately 7-10 days for most patients and vision will remain clear throughout the entire day. After one month of overnight wear, patients may only need to wear the contact lens every other night to maintain 20/20 vision.

Anyone nearsighted with a prescription less than -4.00 who desires freedom from contact lenses and glasses during the day, but does not mind wearing lenses overnight, could benefit from this treatment.

Orthokeratolgy has been shown to be a safe and effective procedure through a number of scientific studies. Orthokeratology is a safe alternative to corrective surgery. It is reversible or can be altered if your prescription ever changes.

Studies have also shown that orthokeratolgy is safe for children and can be used to decrease the progression of nearsightedness.1 The largest clinical trial, involving 102 children, reported slowing myopia progression by 43%.2
