Ortho-K contact lenses are rigid gas-permeable (RGP) lenses. It’s the firm material that is able to reshape the flexible cornea. These lenses still allow enough oxygen to pass through to keep the eyes healthy and comfortable.

Orthokeratology, gives you freedom from spectacles and contact lenses during the day. Those who would benefit the most are:

• Myopic prescriptions – Ortho-K can correct spherical prescriptions up to -5.00D and astigmatism up to -2.50D
• All ages – There are no age limitations
• People who find it difficult to wear contacts due to dry eye, allergies, discomfort, or inconvenience. Ortho-K lenses are worn during the night, which greatly reduces dryness as there is little tear evaporation and, as such, can decrease discomfort
• People who want to swim, ski, and participate in sports without glasses or daytime contacts
• Myopia Control – Reduce the progression of short-sightedness.

Ortho-K is fantastic for children. Numerous studies on myopia (short-sightedness) and Ortho-K have indicated that these lenses can dramatically slow, even stop, the progression of short-sightedness in children. Ortho-K as a method of myopia control reduces the risks of ocular health issues in adulthood related to high levels of myopia.
