LOS ALTOS, CALIF., June 6, 2023—With a goal to continuously improve myopia control adoption and outcomes, SightGlass Vision is presenting a range of new scientific studies and professional education at the 2023 BCLA Clinical Conference. Taking place from June 9-11 in Manchester, England, the event is expected to attract many of the world’s most prominent ocular health experts.
Three-Year Myopia Control Efficacy of DOTTM Spectacle Lenses in Young Children (Laughton D., et al.) centers on a sub-group six-to-seven-year-olds who participated in the company’s pivotal CYPRESS clinical trial, with investigators noting expectations of highly progressive myopia and a paucity of efficacy data for this age group. After three years, myopia progression among these young children was limited to <1.00 D in 60% of Diffusion Optics TechnologyTM 0.2 spectacle lens wearers compared to 21% of control lens wearers. This data— shared for the first time in Manchester—further supports previously announced safety and efficacy outcomes.
Reliability of Quality of Vision Questionnaire Results from Children (McParland M., et al.) assessed pediatric application of the Quality of Vision (QoV) questionnaire, which is more commonly used for adult refractive surgery and intraocular lens research. Investigators abbreviated the standard QoV instrument to focus on glare, hazy vision, and halos, then analyzed responses from CYPRESS clinical trial participants and from their parents/guardians across three years. The greater consistency of within-child agreement compared to parent- child response agreement suggests that parents may under-report their children’s experiences, while also affirming that children as young as age six can share meaningful QoV- derived insights to help inform clinical decisions.
Peripheral Visual Function with DOT Spectacle Lenses for Myopia Control (Aboualizadeh E., et al.) debuts at the BCLA meeting, tapping into the rich CYPRESS data set to review long-term changes in peripheral visual acuity (VA) after three years of Diffusion Optics TechnologyTM spectacle lens wear. Compared to the baseline, peripheral VA improved or remained stable, with no significant differences between the DOT and standard single-vision groups.
