Children adapt well to Essilor’s Stellest lens, which slows myopia progression by 67% on average after two years when worn at least 12 hours a day,1 according to results from a pivotal trial to be presented at the 2021 Annual Meeting of the Association for Research in Vision and Ophthalmology on 6 May.
Stellest lenses provide myopia correction through a single vision lens, which allows for sharp far vision and myopia control through H.A.L.T.2 technology. H.A.L.T consists of a constellation of aspherical lenslets spread on 11 rings and was designed to create a volume of signal that slows down the elongation of the eye.
After two years, children wearing Essilor Stellest lenses saved 0.99 diopters of myopia degree on average
The power of lenslets on each ring has been determined to guarantee a volume of signal always in front of the retina and following its shape, to achieve consistent myopia slowdown.
In 2018, Essilor’s research and development team initiated a three-year state-of-the-art clinical trial on 167 myopic children3 in its joint Research and Development Centre shared with key partner, the Wenzhou Medical University, in China.
Key outcomes include:
● After two years, children wearing Essilor Stellest lenses saved 0.99 diopters of myopia degree on average (67% slow-down in myopia progression on average), compared to single vision lenses, when worn 12 hours or more per day every day.
● After the first year, the eye growth of nine out of 10 children wearing Essilor Stellest lenses was similar or slower than non-myopic children.1
● Two out of three children who wore Essilor Stellest lenses did not need a prescription change after the first year.1
● 100% of children wearing Essilor Stellest lenses had clear vision, 100% of children adapted to their new lenses within a week; 91% of children fully adapted within three days; and 94% of children felt comfortable with Essilor Stellest lenses, demonstrating that Essilor Stellest lenses were comfortable, and easy to adapt for children.1
Norbert Gorny, Co-Chief Operating Officer, Essilor International commented on the results, “With such impressive results, Essilor’s Stellest lenses will truly be a catalyst to stem myopia progression and to help children who continue to be at risk of sight-threatening eye conditions associated with myopia. Essilor is proud to be at the forefront of myopia management and we will continue to be focused on bringing such innovative advances to move the needle on the fight against myopia.”
Grita Loebsack, Group Chief Marketing Officer, Essilor International said, “These exciting results have already amazed leading global myopia experts and illustrate that Essilor’s mission and commitment to tackle myopia remains stronger than ever today. Essilor’s Stellest lenses are one of the most effective myopia control spectacle lenses in the world and a true breakthrough in the optical industry. After its successful release in China in June 2020, then in Russia and Singapore, with extremely positive feedback from parents, children and eye care practitioners, we look forward to offering this new solution to help children in other countries.”
In addition to innovation and research, Essilor is committed to strengthening awareness and education of myopia with governments, healthcare and eye care professionals, and the wider public. Essilor pledged its support for the publication of International Myopia Institute’s landmark white papers in 2019, and is also a member of the industry-wide Global Myopia Awareness Coalition to raise awareness of myopia. Essilor has also recently partnered with leading international myopia educational company, Myopia Profile, to jointly empower eye care practitioners with clinical knowledge, skills and practice in managing childhood myopia.
