Orthokeratology Vision Treatment

Orthokeratology is a method of vision treatment that is sometimes referred to as Ortho-K. It uses special gas permeable contact lenses to reshape the eyes while you are sleeping, allowing you to have a good vision during the day without contacts or glasses. Most people with mild to moderate myopia can benefit from orthokeratology, including people with mild astigmatism. Advantage Eyecare ( offers orthokeratology treatment using Paragon CRT lenses.

Who Can Benefit from Orthokeratology?

Because it is an entirely reversible and non-invasive process, most people who have mild to moderate myopia can benefit from orthokeratology. One of the benefits of this treatment is that it can be used in children with progressive myopia to actually prevent their myopia from getting worse while improving their daytime vision. People who are not candidates for LASIK surgery may also find that ortho-k meets their needs. The use of ortho-k lenses does not prevent people from pursuing laser vision correction later if they choose to.

Ortho-k can correct up to -6.00 diopters or more of myopia. It can be used to correct lesser degrees of hyperopia, presbyopia, and astigmatism. The most common use of the technology is in people with -6.00 diopters of myopia or less, with or without mild astigmatism. Your eye care professional is the best person to ask about whether you are a good candidate for the process or not.

How Orthokeratology Works

Myopia is caused by a slightly misshapen eye and orthokeratology works to correct that. The specialized, rigid lens that is used in ortho-k is naturally pressed tightly against the eye during sleep. This actually reshapes cornea (the surface of the eye), and it maintains this shape for a day or two. Users are able to have a good vision during the day while only wearing the lenses at night.

The Benefits of Orthokeratology

There are a number of benefits of orthokeratology, most of which relate to simply not having to wear glasses or contacts anymore. Active people who do not want to have to deal with contacts or glasses while playing sports are one example. People for whom daytime contact or glasses-wearing is problematic, such as those who must wear eye protection during work or who work in dusty environments, may also find this extremely helpful.

Another benefit of orthokeratology is that it can be used to slow the progression of myopia in children. Childhood myopia tends to get worse, and the use of ortho-k lenses can slow or stop this progression while temporarily correcting current vision issues. Young people also tend to be more active, and ortho-k removes the need to deal with contacts or glasses while playing sports or just plain playing.
