Two-year lens data confirms myopia control

New research from 24-month interim data on spectacles lenses using SightGlass Vision’s Diffusion Optics Technology demonstrates a slowing of myopia progression in children. 


Analysis of the Cypress trial (control of myopia using novel spectacle lens designs) showed statistically significant improvements between groups using Diffusion Optics Technology lenses and the control, displaying 0.21mm difference in axial length and a 0.52D difference in spherical equivalent refraction.  


The prospective, multicentre, subject- and observer-masked, randomised, controlled pivotal clinical study included 256 children aged six-to-10 years old at initiation across 14 trial sites in the US and Canada. At the time of enrolment, study participants had myopia between -0.75D and -4.50D. With a mean age of 8.1 years, the Cypress cohort is younger than children in other well-known myopia management studies, investigators said.  


The findings were presented at the Association for Research in Vision and Ophthalmology (ARVO) meeting 2022. Additional analysis of younger wearers will be presented at the Dutch Contact Lens Conference this month.
