Orthokeratology (ortho-k) is the use of rigid gas-permeable (RPG) contact lenses, normally worn only at night, to improve vision through the reshaping of the cornea. This method can be used as an alternative to eyeglasses, refractive surgery, or for those who prefer not to wear contact lenses during the day.
Corneal refractive therapy is a sophisticated, non-surgical process which reshapes the cornea during sleep. The individual wearing CRT lenses removes the lenses upon awaking and is able to go throughout the day without needing vision correction such as spectacles or contact lenses.
If you can imagine giving up your glasses without surgery, night wear RPGs may be a perfect solution for you. Our optometrists in Lee’s Summit and Lenexa can walk you through the options for non-surgical corneal reshaping including ortho-k.
