Ortho-K FAQ

Frequently Asked Ortho-K Questions at 

Shippee Family Eye Care

Have you heard about an amazing vision correction technology called ortho-k? If so, you may wonder what this technology actually does to correct refractive errors. You may even have been stunned to hear that it can reduce the development of myopia (nearsightedness in kids. Check out these answers to frequently asked ortho-k questions at Shippee Family Eye Care, your trusted optometry center in Lancaster, St. Johnsbury and Montpelier.

What Does "Ortho-K" Mean?

"Ortho-k" is the nickname for orthokeratology. Orthokeratology is a technique for temporarily correcting vision through the use of specialized contact lenses. It is also referred to as corneal refractive therapy, or CRT.

How Does This Form of CRT Correct Vision?

The contact lenses used in ortho-k treatment act as molds designed to change the shape of your corneas, bringing them into line with your corrective vision prescription. Patients typically wear these molds to bed at night and then remove them on awakening. They can then see clearly for as long as the reshaping effect lasts -- with no need for daytime corrective lenses.

How Long Does the Corrective Effect Last?

The corrective effect of ortho-k lenses can vary in duration from person to person. Some people may experience clear vision for a day or so, while in others the effect may last somewhat longer. The temporary nature of the effect is actually an advantage for people who might wish to switch to some other vision correction technique in the future. The effect can also be extended simply by re-inserting the lenses as needed.

What Vision Problems Can Ortho-K Correct?

Ortho-k is most effective against mild to moderate myopia. However, it can also correct hyperopia (farsightedness) and astigmatism. Our optometrist can determine whether this technique can help your condition, or whether you'd get better results with traditional lenses (or even LASIK surgery, which we can co-manage).

Can Ortho-K Really Help to Control My Child's Myopia?

Research has indeed demonstrated that regular use of ortho-k lenses can help nearsighted children experience less myopia development during their formative growing years (when myopia makes most of its progress). This could mean a milder corrective prescription for your child throughout adulthood and less risk of associated eye issues (such as glaucoma and cataracts). Our optometrist can help you decide whether your child should try ortho-k.
