An infographic explaining how myopia control spectacle lens designs work for treating childhood myopia. On the left, under "Single vision correction," it states that peripheral light rays focus behind the retina, encouraging eye growth and increased myopia progression. The diagram shows peripheral light rays focusing behind the retina, leading to the eye growing longer and becoming more myopic. On the right, under "Myopia control design," it explains that lenslets focus light in front of the retina, slowing the progression of myopia. The diagram includes illustrations of the Essilor Stellest and Hoya MIYOSMART lenses, showing light rays focused by individual lenslets and reduced myopia progression. All of the text also appears in French.

Childhood Myopia (part 4 of 4)

By Thomas Weissberger, RO

What responsibilities do opticians have when treating childhood myopia?

“There is no truly successful communication without passion”

Most times opticians are the first and most consistent line of communication with the wearer and their parents. It is up to us to not only determine lifestyles / needs, but to guide the wearer and family towards understanding the need for these types of specialty lenses; and we must do so with passion and positivity.

  1. The optician can use many tools supplied by the major manufacturers to make it easy to give both guidance and explanations to ease both the understanding and apprehensions of the clients.
  2. We can use the expertise available to make it easier to develop a management program for the condition and ongoing treatment.
  3. Clients and their families will remain loyal, and due to the ongoing contact required for the program management, you will see them back in your practice every three to six months, giving multiple opportunities to expand your client base.

Always keep in mind the five precepts of proper fitting, remembering that to be successfully worn and used, the wearer must look through the optical centers.

  1. 15mm from pupil center to top of frame (a minimum distance is required to ensure that the defocus lenselets are present entirely around the central visual area)
  2. Eyes centered vertically and horizontally, choose correctly fitting frames and fit them so that there is minimum movement
  3. Try for rounded corners
  4. Try to maintain the least amount of panto and wrap tilt. The flatter the fit the more effective the action of the peripheral defocus zones
  5. Avoid Frames over 52mm eye size to ensure cut-out of the lens blanks remembering that the lenses cannot be decentered by prism, to ensure OCs are opposite the central line of gaze

The rewards of treating childhood myopia

As ECPs and part of the circle of care team, we have the opportunity to reduce the spread of a major epidemic with potential for catastrophic effects on both the health and life enjoyment of our clients. We need to expand our scope of care and be the ones to help come up with solutions and answers, and to realize that ultimately, we will all benefit, not only from a professional and business standpoint, but also a personal satisfaction feeling that we have truly helped someone.
