SightGlass Vision will continue its Canadian educational webinar series on contrast management for myopia control with a new session drawing on experience from pediatric practice. On Oct. 7 at 7 p.m. ET (4 p.m. PT), the company will host “From Contrast Management to Myopia Control: Insights and Best Practices.” The one-hour session will explore patient cases and firsthand experience using contrast management to slow myopia progression in children.
Canadian eye care professionals interested in attending the webinar can register here.
Kimberley Nguyen, OD, FOVDR, of Vaughan Vision Centre in Vaughan, Ontario, will share her experience prescribing DOT spectacle lenses, available in Canada as MiSight Spectacle Lenses powered by Diffusion Optics Technology. Using examples from her own practice, she will discuss cases where young children with progressing myopia remained stable for several years while wearing the lenses, as well as children who continued to progress with other myopia control approaches and experienced slower progression after switching to contrast management.
“They’re actually my go-to lens, especially for younger children,” said Dr. Nguyen. “I’ve had patients with no progression at all for more than three years. This is the only treatment option in Canada that works just by managing contrast, and because it’s a different mechanism of action, I feel there needs to be more awareness of it among eye care professionals practicing myopia management.”
The Evidence Behind the Lenses
The webinar will also feature Fabio Carta, Dip. Optom, FBCLA, Director of Professional Affairs at SightGlass Vision, who will take a deep dive into the evidence base supporting contrast management for myopia control and the technology behind the lenses. MiSight Spectacle Lenses powered by Diffusion Optics Technology are designed to provide contrast-based myopia control while preserving excellent visual acuity. Other optical interventions that use defocus power may cause refractive blur when the patient views through the treatment zone.[1],[2] Research has found that the lenses saved more than 1D of progression on average after two years in Chinese children aged 6 to 10.[3]*
The session will close with a Q&A for attendees. Another webinar in the series is scheduled for Oct. 21, with details to come. For more information on the Oct. 7 webinar, visit the registration page.
