New Analysis Corroborates NaturalVue 6-Year Data, Presented at Vision By Design Meeting

U.S.-based medical device company and producer of the NaturalVue® Multifocal 1 Day Contact Lenses (‘NaturalVue MF’) Visioneering Technologies, Inc presented a positive analysis of three independent retrospective studies which assessed myopic children wearing NaturalVue MF. NaturalVue MF features the innovative Neurofocus Optics® Technology, which uses an extended-depth-of-focus design to address known optical risk factors associated with the progression of myopia.

The analysis entitled, Consistency in Outcomes – Results from Three Different Retrospective Analyses, was presented by Douglas P. Benoit, OD, FAAO, Executive Director, Medical Affairs for VTI, at the Vision By Design meeting held in Chicago, Illinois, and documents findings across 108 children wearing NaturalVue MF.  Average annual refractive error change in each study was 0.15 D or less at years 1 and 2, significantly less than predicted in age- and ethnicity-matched virtual control subjects. Axial length data was available for two cohorts found to have increased, on average, less than 0.10 mm annually at years 1 and 2 (approximately the amount anticipated in emmetropic children). The CARE value (cumulative absolute reduction in axial elongation) versus age- and ethnicity-matched virtual control subjects in these cohorts were significant and comparable (0.17 mm at year 1 and 0.32 mm at year 2).

The three independently conducted studies included the following:

  1. NaturalVue Monotherapy Subgroup Analysis from The CAMP study (The Clinical Algorithm for Myopia Progression) conducted by Treehouse Eyes®
  2. Myopia Control with Extended Depth of Focus Multifocal Contact Lenses, Carolyn R. Lederman, MD & Edward S. Harkness Eye Institute, Vagelos College of Physicians and Surgeons, Columbia University Irving Medical Center, New York, NY (Presented as a POSTER at the 2023 American Association for Pediatric Ophthalmology and Strabismus 48th Annual Meeting, 29 March-02 April 2023)
  3. Subgroup Analysis from NaturalVue 6-year Retrospective data: Cooper J, O’Connor B, Aller T, et al. Reduction of myopic progression using a multifocal soft contact lens: A retrospective cohort study. Clin Ophthalmol. 2022 Jul; 16:2145-2155.

Myopia progression is caused by eyes growing abnormally in length from front to back which is termed “axial length.”  Axial length change was measured for a subset of the study subjects.** Significantly, the average axial elongation change was approximately 0.10 mm per year through 47 months of follow-up, which approximates that expected for a non-myopic child of a similar age range3 and shows that NaturalVue MF contact lenses help to reduce the anatomical cause of myopia progression.4 To be able to compare the effectiveness of NaturalVue MF to changes observed in children not wearing the lenses, an age and ethnicity matched virtual control group (N=188) developed from 63 randomized clinical trials was used.4,5 This analysis demonstrated a Cumulative Absolute Reduction of axial Elongation (Termed a ‘CARE’ value) of 0.44 mm less axial elongation over 3 years for NaturalVue MF than would be expected for age and ethnicity matched children.3 The use of the CARE value enables ECPs the ability to compare data from one study to another more easily. The CARE value for NaturalVue MF compares very favorably to those of other myopic progression interventions such as orthokeratology lenses, with a CARE value of 0.44 over 7 years, or other soft contact lenses with a CARE value of 0.30 at 3 years.3

To provide the eye care community and potential corporate partners with additional data, VTI will soon report preview data from the 1-year interim results of their PROTECT study, the international multicentered (US, Canada, Hong Kong, and Singapore) double-blinded, randomized, and controlled study of NaturalVue MF in myopic children.

VTI’s Chief Medical Officer, Dr. Ashley Tuan, commented: “Despite having vastly different demographics, with sites spread across America, the results in these three studies were remarkably similar.  This demonstrates that real-world results with this unique design are consistent and repeatable.”
