I was asked what is the 60 second brief on OrthoK so here are my high points along with a video.
Orthokeratology – or·tho·kera·tol·o·gy – a treatment for improving vision by altering the shape of the cornea through the application of corneal molds that are worn while you sleep.
Adult patients, kids, and parents alike express amazement at how we can alter or mold the shape of the cornea with a contact lens, resulting in clear vision during the day without the need for glasses. It’s not magic, the science is very well established and FDA approved. We remold the cornea like what is done in LASIK. The difference is that Ortho-K achieves this without the use of a laser, it is reversible, and it is easily modifiable.

The study of myopia control (nearsightedness) is a hot field of study, particularly in China where the High Myopia – Partial Reduction Orthokeratology (HM-PRO) study was conducted. This study is the latest in an effort to find an effective means to slow or even stop the progression of nearsightedness in children. The HM-PRO study is unique in that it treated 18 highly myopic children (Rx over -5.75 D) between the ages of 8 and 11 with a combination of OrthoK lenses and glasses, and followed them for two years. The study participants were matched with a control group of 18 children, the same age and also with prescriptions over -5.75D.
In the HM-PRO study 18 participants and 18 control patients were followed for 2 years. 15 of the treatment patients and 13 control patients completed the study. After two years the treated patient’s nearsightedness increased by – 0.13D and the untreated (control) patients increased their nearsightedness by -1.00D.
Myopic progression is also measured by how much the eye grows in length (called the axial length). In this case the treated patients showed a significant reduction in progression with their axial length increasing by 0.19 mm whereas the control group’s axial length increased by 0.51 mm.
The study authors concluded that orthokeratology lenses slowed axial length elongation by 63% and reduced the prescription change by 87%. It has yet to be shown that orthokeratology lenses stop the myopic progression clearly this study, like numerous other before it, show that orthokeratology is effective in markedly slowing the progression of nearsightedness in children. At Total Eye Care we have been using reverse curve orthokeratology lenses to control myopia since 1999 and have fit hundreds of kids and adults.

With the increased rate of myopia in the US population, orthokeratology is becoming an increasingly important treatment option for our patients. Dr. Driscoll is a member of the Orthokeratology Academy of America that produced the excellent video shown below. The video gives a comprehensive overview of orthokeratology, including its pros, cons, and how it works. We highly recommend that any patients considering refractive surgery, such as LASIK and PRK, or orthokeratology view this video. By the way, comments are much appreciated so don’t be shy.
Total Eye Care unveiled OrthoKDoctor.com a new website designed to answer patient questions about Orthokeratology, a safe and effective alternative to refractive surgery
Orthokeratology is known by numerous terms, the most common of which are Gentle Vision Shaping System, OrthoK, Corneal Refractive Therapy and Overnight Vision Correction. Total Eye Care introduces the new website OrthoKDoctor.com to inform patients about this exciting technology.
“Orthokeratology is a safe and gentle method where contact lenses temporarily reshape the cornea while a patient sleeps. The beauty of OrthoK is that it is temporary. As long as a patient wears a retainer lens the effect remains, much like wearing a retainer after orthodontic braces are removed” says Dr. Richard Driscoll, clinical director at Total Eye Care.
We have extensively updated our article on the Gentle Vision Shaping System
™ also known as Orthokeratology or Corneal Refractive Therapy, on the Total Eye Care website. I’d love to hear some feedback.
Study from Ohio State University Confirms Prior Studies Myopia Slowed With Contacts
In February, here in The Eye Doc Blog, we reported that The CANDY Study showed that OrthoKeratology contact lenses markedly slowed the progression of nearsightedness in children. The results of The CANDY study have now been confirmed in the British Journal of Ophthalmology, the new study, Corneal Reshaping and Myopia Progression, showed that children wearing corneal reshaping lenses, also known as ortho-K or orthokeratology lenses significantly reduced the rate of change of the length of the children’s eyes. The study participants wore the lenses for two years and ranged in refractive error from -0.75 to -4.00. The study concluded that previous reports of slowed eye growth following corneal refractive therapy were confirmed.

I came across this video on orthokeratology . I believe it is from 2002, however it is still very relevant and the information still applies to how ortho-k is a safe, viable, non-surgical option to vision correction. Studies have also shown that overnight ortho-k may prevent or slow the progression of nearsightedness in children.
