Dr Aller, who is a practicing optometrist and Visiting Scholar at the UC Berkeley School of Optometry, highlighted how VTI’s unique contact lens design continues to show promise in managing nearsightedness in children (paediatric myopia).
Between October 2017 and January 2018, multiple eye care practices released peer-reviewed data showing nearly 60 children for whom NaturalVue Multifocal had slowed the progression of nearsightedness by 96% on an annual basis.1,2It is generally thought that minimizing the progression of nearsightedness is an important intervention aimed at minimizing life-time risks of blindness and other serious ocular diseases that are related to nearsightedness.
Starting in 2017, Dr. Aller spearheaded a prospective, registered clinical trial (NCT03358862) with the objective of quantifying changes in vision (refractive error) and eye shape (axial length) in myopic children wearing NaturalVue Multifocal contact lenses. To date, 24 children have completed at least one 6-month follow up visit, and 19 children have worn the lenses for more than one year. The average age of this sample population was 10.8 years old (range 7-17), with approximately half of the children (50%) having some Asian ethnicity.
Prior to wearing NaturalVue Multifocal, the children were worsening in their myopic vision by 1.28 ± 0.79 dioptres per year, a rate of worsening that many practitioners consider to be quite aggressive, given that the average amount of progression is approximately 0.50 dioptres per year.3 In contrast, children wearing NaturalVue Multifocal experienced a rate of worsening of 0.24 dioptres per year, a decreased change of 1.04 dioptres per year (statistically significant, P<0.01), representing an 81% decrease in the rate of myopia progression.
In addition, the children in Dr. Aller’s study who wore NaturalVue Multifocal experienced slower changes to the shape of their eyes, compared to the rate of change one would expect in children with a similar level of aggressive worsening of myopia. Using published estimates of axial length change based on the prior year’s refractive error change (1 mm=3.00 D),4 these children would have been predicted to have shown an increase in axial length of 0.43 ± 0.26 mm in the year prior to wearing NaturalVue MF. With NaturalVue MF, the 19 children who have worn the lens for at least one year demonstrated an axial length change of 0.20 ± 0.19 mm in one year. This level of axial length growth in these fast-progressing children wearing NaturalVue Multifocal is very encouraging.
Combining Dr. Aller’s data with previous studies on NaturalVue Multifocal, the average follow up period was 12 months, with some children reaching 36 months of NaturalVue Multifocal wear in 2018. On average, 97% of more than 80 children showed a decrease in their rate of myopia progression, with an average decrease of 0.93 dioptres per year.
“The prevalence of myopia is increasing among children globally at alarming rates, and identifying better ways to manage myopia has become a top priority for vision care experts worldwide,” said Dr. Aller. “The NaturalVue Multifocal data are very encouraging based on the level of decrease in changes in both refractive error and expected axial length growth, especially in a group of very fast progressing myopic children. To achieve more than 1.00 dioptres of decrease in myopic refractive error change on a prospective basis after one year is quite remarkable and promising. The unique design of NaturalVue Multifocal offers intervention for multiple potential causes of myopic progression, and its availability as a daily disposable contact lens makes it ideal for use in children. I am excited to continue this research and follow these children into their second year of wear.”
NaturalVue® (etafilcon A) Multifocal 1 Day Contact Lens Indication for Use in Europe and Australia and New Zealand:NaturalVue (etafilcon A) Multifocal Daily Disposable Soft (Hydrophilic) Contact Lenses are indicated for daily wear for the correction of refractive ametropia (myopia and hyperopia) and/or presbyopia, and myopia progression control in aphakic and/or non-aphakic persons with non-diseased eyes in powers from -20.00 to +20.00 dioptres and with non-diseased eyes who may require a reading addition of up to +3.00D. The lenses may be worn by persons who exhibit astigmatism of 2.00 dioptres or less that does not interfere with visual acuity.
About Visioneering Technologies, Inc.
Visioneering Technologies, Inc. (VTI) is a US-based medical device company primarily engaged in the design, manufacture, sale and distribution of a revolutionary new contact lens: the NaturalVue® Multifocal (MF) contact lens. The NaturalVue MF contact lens employs VTI’s Neurofocus Optics® technology, which was developed, refined and tested over many years. The characteristics of the NaturalVue MF contact lens allow it to be used in two of the largest eye-care markets globally: adults with presbyopia (age-related difficulty in seeing close objects) and children with myopia (near-sightedness, or difficulty seeing distant objects).
NaturalVue lenses were cleared by the FDA in late 2014 and received the CE Mark, as well as TGA approval in early 2018. VTI recently commenced its US market expansion for NaturalVue MF contact lenses, and has broadened its reach into international markets in 2018. VTI also sells and plans additional contact lens products.
