NaturalVue multifocal lenses slow axial elongation, refractive error change in children

Visioneering Technologies, which manufactures NaturalVue Multifocal 1 Day contact lenses, has released a new analysis of three independent studies that assessed the lenses over 2 years in children with myopia.
According to a press release from Vision Technologies, the lenses feature Neurofocus Optics technology and are designed with extended depth of focus to treat risk factors linked to myopia progression. The lenses recently were assessed in three retrospective studies that included 108 children, who were evaluated after 1 and 2 years of lens wear.
Results showed that the average annual refractive error change was 0.15 D or less at years 1 and 2 — significantly less than predicted in age- and ethnicity-matched controls. In addition, axial length data reported among two cohorts showed an average increase of less than 0.1 mm annually, with comparable cumulative absolute reduction of axial elongation vs. controls at years 1 and 2 (0.17 mm and 0.32 mm, respectively).
“Despite having vastly different demographics, with sites spread across America, the results in these three studies were remarkably similar,” Ashley Tuan, OD, PhD, Visioneering Technologies’ chief medical officer, said in the release. “This demonstrates that real-world results with this unique design are consistent and repeatable.”
Preview data from the company’s PROTECT study, an international multicenter study of the lenses in myopic children, will be reported soon, the release stated.
