This retrospective study assessed the relationship between baseline axial length and subsequent elongation for myopes wearing orthokeratology lenses. The results showed axial elongation was slower over two years for younger children with longer baseline axial lengths. This may help in approaches to optimizing myopia control.
We speak to Peter Nijhuis, Division Head Myopia Management Business Division at Menicon about the Menicon Bloom comprehensive system for myopia management with contact lenses, and about three years of experience in the Netherlands with this landmark system.
The evolution of soft contact lens design from myopia control has come from presbyopia designs to a variety of options today. The newest design is concentric annular zones with noncoaxial relative plus power, called RingBoost technology. The aim is to deliver a high level of relative plus power for increased myopia control efficacy with minimal visual impact – learn more here.
Johnson & Johnson Vision’s intent to lead with science was on full show at the recent ARVO at New Orleans. We look at 5 abstracts they presented, providing you summaries and the abstracts on topics such as efficacy in myopia control, myopia calculators and subjective vision outcomes for children and teens in soft contact lens designs for myopia.
This study found that over a 4-yr period, only 2% of children discontinued ortho-k wear, and the reasons were primarily due to adherence to lens wear schedules. This appears to be lower than in soft contact lenses. Encouraging children to continue wear as prescribed throughout the adaptation period, and to maintain compliance, should reduce likelihood of drop-out.
Data from up to six years of wear in the landmark MiSight® 1 day clinical trial has shown similar outcomes for comfort, vision, handling and overall satisfaction compared to children wearing Proclear® 1 day single vision lenses. Children 11-15 years who were refit from single vision to MiSight 1 day also rated lenses highly and increased their contact lens wearing time.
This study examined rates of corneal infiltrative (or inflammatory) events, including microbial keratitis, in nine studies. Most study data was for children fitted at 12 years of age or younger and most wore daily disposables. Taking in data for almost 3,000 children and over 6,000 patient-years of wear, rates were found to be low, adding to the body of evidence that children appear to be safer soft contact lens wearers than adults.
We speak to these leading clinical researchers on the science behind the MiSight® 1 day contact lenses and how the findings of this study can be translated into clinical practice. Both Professor Debbie Jones and Professor Nicola Logan were investigators in the MiSight 1 day clinical trial, which is the longest-running soft contact lens study involving children.
This reanalysis of data from 2 clinical trials evaluated the relative risk of fast axial eye growth in children wearing ortho-k lenses. The results showed that although younger children (6-8 years) experienced faster eye growth than older children (9-12 years), they also benefitted more from ortho-k in slowing their progression when worn for a 2-year period.
The MiSight 1 day clinical trial is the longest-running soft contact lens study among children, and is now reporting seven-year data. With questions explored including efficacy, cross over from control group to treatment and discontinuation, here’s some of what we’ve learnt along the way.
