Ortho Keratology Lens iN NEpal

What is Orthokeratology? Ortho-K in Nepal

Orthokeratology is a non-surgical myopia correction method

The lens used in Orthokeratology treatment is called an Ortho-k lens or OK lens. It is a Rigid Gas Permeable (RGP) lens and is usually worn at night and removed the next morning. It changes the shape of the cornea and corrects your vision for a certain period so you can have a comfortable vision without wearing anything after removing the Ortho-k lens. The correction is temporary therefore you have to wear the Ortho-k lens on a regular basis. On the other hand, you can quit the treatment anytime and the shape of the cornea is restored.
