NIH Study Commissioned to Examine Prevention of Nearsightedness with Soft Bifocal Contact Lenses

Posted on June 1, 2014 | 4 comments

Bifocal Lenses in Nearsighted Kids (BLINK) Study Begins

The National Institutes of Health awarded the University of Houston College of Optometry and the Ohio State University College of Optometry $7.5 million to study the use of soft bifocal contact lenses in the prevention of nearsightedness (myopia) in children. The Bifocal Lenses in Nearsighted Kids (BLINK) Study will follow 300 children, ages 7 to 11 years of age over a period of 3 years. The Ohio State University College of Optometry previously published the Corneal Reshaping and Myopia Study in a 2009 issue of the British Journal of Ophthalmology where it found that orthokeratology lenses were effective in preventing the lengthening of the eyeball in children which in turn slowed the progression of nearsightedness.

Florida State Heisman Candidate QB Jameis Winston Gets OrthoKeratology!

Posted on November 5, 2013 | 1 comment

Jameis Winston Gets Orthokeratology Lenses

Jamies-Winston-OrthoKThe sports pages were all atwitter this weekend talking about how, the FSU quarterback, Jameis Winston doesn’t like to wear his contacts while playing football. He is afraid they will pop out. Problem solved, squinting Jameis Winston  decided to get  OrthoKeratology. The commentators of the FSU-Miami game even commented on how the Heisman candidate QB was squinting to see which play the coach was calling from the sideline. Yahoo News also shows him squinting to find a receiver downfield.

No matter how good you are you will play, and perform at a higher level with better vision. A fact not lost on Winston’s coach, Jimbo Fisher. At the post game press conference Fisher stated “imagine how good he would be if he could see.” I concur, now he will be able to see the eyes of the defender, and his receiver’s, a huge benefit for players at any level. Look out Wake Forest and Syracuse.

What is Orthokeratology

Orthokeratology allows nearsighted patients of all ages to achieve clear vision without glasses or contact lenses. OrthoKeratology has also been shown to be effective in slowing, and in some cases stopping the progression of nearsightedness in children. More information on Orthokeratology at Total Eye Care is also available on the OrthoKDoctor.com website.

Summer – A Great Time for Orthokeratology

Posted on August 5, 2013 | Comments Off on Summer – A Great Time for Orthokeratology

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.

Check out the video below and see what patients are saying about Orthokeratology. If you want to know more about Orthokeratology call our office for a free consultation 817.416.0333 or visit www.OrthoKDoctor.com

Study Shows Orthokeratology Effective in Reducing the Progression of Nearsightedness in Children

Posted on May 11, 2013 | 5 comments

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.

Excellent OrthoKeratology Video

Posted on January 23, 2012 | 3 comments

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.

Dr. Driscoll Attends International Orthokeratology Academy Meeting

Posted on May 14, 2011 | Comments Off on Dr. Driscoll Attends International Orthokeratology Academy Meeting

April 28-May 1, 2011: Orlando, FL —Richard A Driscoll, O.D. attended the Orthokeratology Academy of America Educational Conference. In keeping with Total Eye Care’s philosophy of providing a complete solution to their patients visual needs Dr. Driscoll has furthered his knowledge in the area of Orthokeratology a procedure where patients wear a vision retainer at night, remove the lens during the day and experience good vision all day long. Says Dr. Driscoll, “some patients simply are not surgical candidates for LASIK or PRK and want a safer alternative to refractive surgery, Orthokeratology provides that safe, effective surgical alternative.”

Current research also shows that the same vision retainers used in Ortho-K can slow myopic progression in children. Said Dr. Driscoll “parents often ask if there is anything they can do to prevent their child from becoming more nearsighted. We can now tell them that studies show Orthokeratology vision retainers significantly slow the progression of nearsightedness in children. New lens designs were also discussed at the meeting and we expect they will be shown to be even more effective. Early reports on these new lens designs will likely be presented next year.”

The keynote address, Myopia as a Public Health Concern, was given by Melbourne Hovell, Ph.D., M.P.H. The international faculty of presenters covered topics including myopia control (including soft lens technology), corneal reshaping research, safety of corneal reshaping, progressive/hyperopic Ortho-K lens designs, new corneal reshaping technologies, post LASIK lenses, Keratoconus / Ortho-K lenses, lens designs for corneal rehabilitation, corneal cross-linking and Ortho-K in China. “This is by far the most widely attended meeting on Orthokeratology and myopia control in the world. There were doctors in attendance from every continent except Antarctica” said Dr. Richard Driscoll, “controlling the progression of myopia was a central theme to the meeting.”

President Dr. Cary Herzberg had the pleasure of announcing the inception of the new International Academy of Orthokeratology(IAO). The IAO brings together Ortho-K organizations from the United States (OAA) as well as Europe and Asia. This international organization will support, promote and advance corneal reshaping worldwide through quality education and research presentations at meetings held around the world.

National Public Radio’s Medical Detectives Explore Increased Nearsightedness in the US

Posted on February 4, 2010 | 1 comment

Photo of Child gazing out windowIn December 2009 we covered the results of a recent study Myopia Increasing Rapidly in The US Population. Recently National Public Radio’s Medical Detectives interviewed, Dr Susan Vitale, principle author of the study “1994-2004 National Health and Nutrition Examination Survey” and Dr. Don Mutti, an expert in myopia.  It’s a good listen and only a little over 3 minutes.

With myopia increasing at such a rapid rate in our population will it be long before the use of orthokeratology to slow the progression of myopia in our children becomes the standard of care?

Study Says: Myopia Increasing Rapidly in The US Population

Posted on December 22, 2009 | 6 comments

The rate of nearsightedness in the US  has increased by over 66% in the past 30 years says a study published in the December 2009 issue of Archives of Ophthalmology

Thick GlassesA 66% increase in myopia is a huge change over a 30 year period. The new study tried to simulate the testing methods of the original 1972 study on nearsightedness in the US population.  The 1971-1972 National Health and Nutrition Examination Survey found that 25% of the US population between the ages of 12 and 54 were nearsighted vs the 1994-2004 National Health and Nutrition Examination Survey’s finding of 41.6%.  Increased nearsightedness was noted regardless of age, sex, race or education.

The authors concluded that it would be beneficial to identify behavioral risk factors that cause increased myopia.  If risk factors for increasing myopia are identified we may be able to slow the progression.

The big question is “what caused this increased nearsightedness in the US population”?  As eye doctors we are often asked what causes nearsightedness and the usual answer is that that we believe nearsightedness is a combination of genetics and environmental influences.  In the last 30 years our society has become much more near centric.  People spend hours glued to their computer monitors at work and home. Kids spend more time at near now then ever before with computer games, hand held games etc.

Numerous recent studies have shown that orthokeratology contact lenses can greatly slow the progression of nearsightedness

Finding ways to slow or halt the progression of myopia has been a longstanding subject of study in eyecare.  The process of using special contact lenses to reshape the front part of a patient’s eye to prevent the progression of nearsightedness and to allow the patient to see without glasses is called orthokeratology.  There are a number of different names for orthokeratology, orthoK, corneal molding, corneal reshaping and corneal refractive therapy are some of the most common names.

Almost a year ago the study, Controlling Astigmatism & Nearsightedness in Developing Youth (CANDY) showed that orthokeratology contact lenses reduced the progression of nearsightedness in kids between 9 and 16.  The authors of the CANDY study found that the amount myopia in children that did not wear the overnight Corneal Refractive Therapy lenses increased at a rate of .37D per year while those children wearing  the lenses progressed at only .03 diopters per year.

Another study, Corneal Reshaping and Myopia Progression published in the British Journal of Ophthalmology, conducted at the Ohio State University College of Optometry found that the eyes of the children wearing overnight orthokeratology lenses increased in length at a markedly slower rate than the studies’ non ortho-K lens wearers.

Lastly, the study Stabilization of Myopia by Accelerated Reshaping Technique (SMART) is in the first  of its five years and this past summer released preliminary results showing that again, orthokeratology lenses appear to markedly slowing the progession of nearsightedness in children.

While the rate of nearsightedness in the US population has increased significantly in the last 30 years it is comforting to know that there are safe and effective methods of slowing the progression of myopia.  Download a PDF of the study Increased Prevalence of Myopia in the United States Between 1971-1972 and 1999-2004

Encouraging Early Results in Nearsightedness Prevention Study

Posted on July 10, 2009 | 2 comments

The first year of the Stabilization of Myopia by Accelerated Reshaping Technique (SMART) Study has produced some encouraging results in a recent announcement.  According to Dr. Robert L. Davis, co principal investigator of the SMART trial,  “The net effect of this contact lens fitting philosophy is to change the cornea shape for the sole purpose of reducing the amount of myopia as measured by change in refraction” .  “The results of the SMART Study so far are very exciting,” said Dr. Davis. “The outcomes of this study may revolutionize how we manage young nearsighted patients from this point forward”.

The SMART Trial involves 300 patients between the ages of 8 and 14.  The goal of the study is to see if having patients where overnight orthokeratology or corneal molding lenses will stop or slow the progression of nearsightedness.  The SMART Trial is the largest of its kind.  Other studies have also shown that preventing nearsightedness with ortho-K contact lenses is possible, such the CANDY Study.  A study from Ohio State Unversity suggested that wearing Ortho-K lenses overnight actually prevented the eye from becoming longer.  The SMART Trial has just completed the first year of the five year study.  We will continue to keep an eye on this potientially ground breaking study.

Study Finds Nearsightedness Slowed in Children With Contact Lenses

Posted on February 23, 2009 | 5 comments

It’s good to see another study indicating that Orthokeratology Contact Lenses prevent the progression of nearsightedness (myopia).  The Controlling Astigmatism & Nearsightedness in Developing Youth Study (CANDY) was based on a relatively small population (28 patients) and it would have been good to see the rate of myopic progression after removing the contact lenses over a greater period of time, however the data was compelling and warrants further study.

As eye doctors we are often asked if we can prevent the progression of nearsightedness in children.   Clinically, we feel that the answer is probably yes, however there are relatively few studies that have investigated this common question.  The CANDY Study backs up what we feel our clinical experience has taught us.  The progression of nearsightedness in CANDY study patients was 0.37D prior to wearing overnight Ortho-K contact lenses.   When the patients discontinued wearing their lenses they found that the patient’s refractive error, on average, had increased by only 0.03D.

An FDA sponsored study of 300 children started in 2007 and is expected to continue for 5 years.  Hopefully, the FDA study will answer more of our questions.  Additional findings from the CANDY Study found that the younger the child the more beneficial was the effect on controlling myopia and the technique was more convenient.   A more comprehensive look at Orthokeratology including a link to the CANDY Study is available on the Total Eye Care website.
