Orthokeratology (Ortho-K)

Are you tired of wearing contact lenses or glasses every day?  Would you enjoy the freedom of having clear vision all day without corrective lenses or eye surgery?  If so, Ortho-K (also referred to as Corneal Refractive Therapy [CRT]) may be a great option for you. 

Alternative to LASIK Eye Surgery

Orthokeratology or Ortho-K is a fitting procedure that temporarily reduces nearsightedness and astigmatism.  The lenses are worn while sleeping and removed upon awakening.  The lenses are designed to reduce your refractive error by gently changing the shape of the cornea.  The contact lenses must be worn each night to maintain the effect.  The vast majority of patients maintain clear and comfortable vision for all of their waking hours.   

Ortho-K: An Old Idea with New Advancements

Reshaping the cornea with contact lenses to improve vision is not a new idea. Orthokeratology has been practiced for decades. In the past ortho-k produced mixed results because the technology to create the proper lens was not as advanced as it is today and the process wasn't FDA-approved, so the procedure had limited appeal.

Today, new manufacturing methods and lens designs are enabling orthokeratology lenses to achieve much higher success rates than experienced in the past. The performance of so-called "reverse geometry" designs have fueled new excitement about orthokeratology.  Orthokeratology now offers patients the opportunity to have clear vision all day without the inconvenience of traditional contact lenses or eyeglasses, and represents an alternative to LASIK eye surgery.  Ortho-K is not eye surgery and is a completely reversible process. 

In 2002, Paragon CRT received FDA approval as a safe and effective treatment option for individuals of all ages.  Learn more at www.okglobal.org and www.paragoncrt.com
