Ortho-K Lenses

How Ortho-K Works

• The corneal surface is gently reshaped by the special design of the lenses, adjusting the curvature of the cornea.
• After a period of wear, usually 6–8 hours, the cornea temporarily changes shape, allowing the eye to focus light properly onto the retina and improving vision.
• The effect lasts until the cornea gradually returns to its original shape, typically for 12–24 hours. Therefore, Ortho-K lenses need to be worn regularly every night to maintain the results.
