Long-term study shows daily disposables ‘have minimal effect’ on children’s ocular physiology

Recently published results of an extensive study into the physiological response to daily disposable soft contact lenses are adding to a growing body of evidence in support of contact lens wear in children for myopia control.

The study, published in the British Contact Lens Association’s peer-reviewed journal Contact Lens and Anterior Eye, highlights the long-term ocular health of children wearing daily disposable soft contact lenses and reports minimal impact on physiology over six years.

Sponsored by CooperVision, it is the longest known study to specifically report on physiological response to daily disposable soft contact lens wear in young children and adolescents.

Ms Jill Woods, head of clinical research for the Centre for Ocular Research & Education (CORE), was the paper’s lead author.

Woods’ team followed 144 children as part of an international multi-centre, double-masked, randomised, controlled clinical trial for CooperVision’s MiSight 1 day contact lenses, which are currently available in 26 countries including Australia and New Zealand.

Across the entire six-year study period, there were no contact lens-related serious adverse events.

The low incidence rate of corneal infiltrative events were similar to rates in adults wearing one day lenses, equivalent to 6.1 per 1000 wearing years.

Additionally, ocular health, as determined by biomicroscopy after six years of full-time wear – representing more than 5,000 aggregate measurements of each variable, assessed at six-month intervals – was similar to baseline observations prior to commencing lens wear. The paper also discusses the many factors affecting contact lens wearing success, including lens fit, lens material and surface, and patient habits.

“Ultimately, our work suggests that placing children in daily disposable contact lenses is a successful way to correct their vision, in addition to the myopia control benefits of MiSight 1 day,” Woods, who is also an investigator for the MiSight 1 day clinical trial, said.

She said the study results should provide eyecare professionals and parents even more assurance when considering myopia control options.
