Clear distance vision is rapidly becoming a rare privilege around the world, especially in Asia, due to increasing prevalence of myopia. The worldwide prevalence of myopia is predicted to increase from the current 23% to 50% in the next three decades. Although much effort has been directed towards elucidating the mechanisms underlying refractive eye development and myopia, treatment options for myopia are mostly limited to optical correction, which does not prevent progression of myopia or pathological blinding complications often associated with the disease. Several experimental optics-based treatments can only slow the progression of myopia, but cannot stop it. Currently available drug treatments are limited and the mechanisms of action not well understood. The development of safe and effective pharmacological treatments for myopia is urgently needed to prevent the impending myopia epidemic. The main obstacles that have been preventing the development of anti-myopia drugs are the uncertainties regarding the mechanisms controlling eye growth and optical development (emmetropization), particularly the molecular signaling pathways underlying it. Our results provide direct evidence that the retina can recognize the sign of optical defocus and can generate molecular signals specific to the sign of defocus. Contrary to conventional thinking that myopic and hyperopic defocus regulate emmetropization by triggering opposite changes in the same genes and pathways, we found that defocus of opposite signs affects eye growth via largely distinct retinal pathways. Knowing that myopic and hyperopic defocus signals drive eye growth in opposite directions and propagate via different pathways provides a framework for the development of new anti-myopia drugs. Myopia can be controlled pharmacologically by stimulating pathways underlying the retinal response to positive lenses and/or suppressing pathways underlying the retinal response to negative lenses.

Atropine 1% and various lower concentrations of atropine (0.5-0.01%) have been used to slow the progression of myopia. Cumulative data and meta-analysis from a number of studies have demonstrated that the most effective method for slowing the progression of myopia is atropine 1% instilled daily ( progression is slowed by almost 80%). Atropine’s side effects of mydriasis and cycloplegia have kept it from being prescribed more frequently.

Recent studies have demonstrated that lower concentrations of atropine 0.025% to 0.01% are effective with significantly lower side effects. Discontinuing atropine treatment has displayed a rebound of myopia progression with higher amounts of rebound associated with higher atropine concentrations. Ocular side effects of atropine can be effectively managed with photochromic progressive lenses. In summary, atropine is not only safe, but it is also an effective drug to slow the progression of myopia.

  1. Understand the indication for hyperopic orthokeratology
  2. Understand how hyperopic ortho-k differs from myopic ortho-k
  3. Understand the topographical changes required in successful hyperopic ortho-k
  4. Understand the indications patient selection for hyperopic ortho-k
  5. Understand the step-by-step fitting procedure for successful hyperopic ortho-k
  6. Understand the various software progams available for hyperopic ortho-k

Seminar: Onefit™ MED

Dr. Sandrine Malaison Tremblay, OD will explain how the Onefit™ MED advanced scleral lens design allows you to design the ideal scleral lens for highly irregular and medically indicated corneas, including a wide-range of ectasias (moderate to severe), as well as healthy corneas when a larger diameter is needed. With Onefit™ MED, you are in complete control of the design and fit, with the ability to customize parameter options in four fitting zones: Central, Mid-peripheral, Limbal and Edge. You can design the lens further with quadrant specific edge zones and the option to use the Controlled Peripheral Recess (CPR) technology when a precise recess is needed to accommodate any type of scleral elevation.

Location: Princess Ballroom

Presented by: Dr. Jeff Goodhew

Seminar: Spectacle Lens Therapy in Myopia Management

Myopia prevalence in the Western world is on the rise. A recent Canadian study estimated that 6% of Canadian school children between the ages of 6-8 are myopic, with the number soaring to 28.9% in children aged 11-13*.  ZEISS Myopia Control spectacle lenses are proven to be a better solution than single vision or standard progressive lenses when it comes to managing myopia progression.

This session looks at several solutions in spectacle lens therapy including study results evaluating the effectiveness of both single vision but especially multifocal lenses in treating myopia.  It highlights two novel spectacle designs launched by ZEISS in 2018 that address the two main theories causing myopia progression: peripheral defocus theory and accommodative lag theory.

This seminar is presented by Dr. Jeff Goodhew.  Dr. Goodhew is a partner in Abbey Eye Care, a full scope independent practice located in Oakville, ON. He enjoys seeing all patients in a primary eye care setting but has developed several niche offerings including myopia control, glaucoma management & dry eye therapy.  Jeff is also very involved in the Optometry profession. He currently sits on the board of directors of the Ontario Association of Optometrists and served as president from 2014 – 2016. Along with his spouse Dr. Tina Goodhew they serve as co-editors of Canadian Eye Care Business Review.

This presentation will discuss issues relating to the effects of OrthoK correction on Vision-related Quality of Life(VR-QOL). VR-QOL is more than just how well can you see. It involves numerous other attributes that are not easily measured during a routine office visit. There are visual, psychological, emotional and activity-based factors that contribute to your patient’s overall VR-QOL.

The course will review results of peer-reviewed studies, validated QOL instruments and how this relates to overall patient care and management.

Myopia is a significant health problem affecting more than 30 % population in North America. The prevalence of myopia in urban East Asian countries is even higher-over 50%. In addition to the increase in the prevalence of myopia in recent years, there is an alarming upsurge in extreme level of myopia and associated ocular pathologies. Therefore, the conventional approach to correct myopia with glasses is no longer the best standard of practice. Myopia should be considered like glaucoma, macular degeneration, diabetes and other diseases. Eye care providers should screen for children likely to become myopia and incorporate new control strategies for tighter management of myopia. Over the past two decades, several well-designed clinical trials on spectacle lenses have shown varying success for slowing myopia progression. The earlier strategies include the use of bifocals and progressive addition lenses to reduce accommodation and to enhance near-point retinal focus. More recently, the emphasis has been shifted to the use of concentric multifocal addition lenses to reduce peripheral retinal hyperopic defocus. Despite these efforts, to date the best spectacle myopia control therapy can only reduce myopia progression by about 60 %. Has spectacle lens therapy already reached its maximum potential for myopia control? This talk will review the concept of spectacle lens therapy for myopia control and how animal and human studies help to advance the optical control methods. The clinical application of different spectacle options and the future research direction will also be discussed.
