The orthoK lens - How and why it works

You can fit an orthoK lens without understanding how it works.  But then you are just a mechanic, not a practitioner.  Learn how the cornea is reshaped thru fluid forces, where do the cells migrate.  Learn what are the component curves of an orthoK lens and the function of each curve.  Watch as the curves are manipulated and how this affects the fit and treatment of this lens.  Understand the function of changing the diameter of a mold lens.  Astigmatism presents a challenge but you will learn how to recognize the various types and create the appropriate toric design to produce an excellent outcome.  You will view numerous NAFL slides showing different lens designs on toric corneas.

                  Orthok is an extremely effective method employed for myopia control.  How does the orthoK lens design differ when you are trying to control myopia?  You will find out.

                  Finally, newcomers have concerns about the safety of orthoK.  They are often required to defend orthoK treatment when parents are told it is unsafe by a child’s pediatrician.  Learn about the studies that validate the safety so that you can educate and calm your questioning parents.

Myopia Control

Myopia is at epidemic proportions.  We need facts and data in order to educate our patients and make them understand the seriousness of the disease.  You will be provided information regarding the increased numbers of myopic children.  You will learn how increasing myopia increases the risk for several types of ocular disease (with supporting studies).  These data will help when counseling parents to institute myopia control treatment for their kids. 

You will be shown  the various components of a myopia control program including soft orthoK, pharmaceutical control, behavior intervention and of course, myopia controlling orthoK designs….this is not your mother’s orthoK lens.

Learn how to integrate this protocol in to your examination.

The theory (and supporting data) for how myopia is controlled with orthoK will be discussed.  The orthoK lens will be dissected curve by curve.   You will learn how to create the peripheral plus necessary to slow myopic creep.  It is a distinctly different design than traditional orthoK.
