Orthokeratology (ortho-k), also called Overnight Vision Correction, Wavefront Corneal Molding, and Corneal Refractive Therapy (CRT), is the unique custom-designed, gas-permeable rigid contact lenses that you wear overnight. While you are asleep, the lenses gently reshape the cornea in order to correct your vision. After you remove the lenses the following day, you can see clearly.
