The Defocus Incorporated Multiple Segments (DIMS) clinical study included a two year randomized controlled trial, which then extended to investigate continued efficacy over six years of wear, plus groups who switched from single vision to DIMS and back again. There was no evidence of a rebound effect. Visual acuity and binocular visual functions were similar across groups.
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.
This editorial evaluated a range of single and multi-country clinical trials to examine the impact of race on treatment efficacy in myopia control. The authors found a similar slowing of axial elongation and myopia progression for East Asian and non-East Asian children across all studies.
A new study has shown that an ‘extra compression factor’ of 1D, which is essentially increasing the treatment target, improved myopia control outcomes for children wearing orthokeratology. This would seem to indicate a different approach is needed for myopia control, but delving into the study reveals the story is not that simple.
Repeated low-level red light (RLRL) therapy is showing impressive results for myopia control in children, with a two-year randomized controlled trial showing highly impressive results for slowing and even reversing axial elongation. While reported as safe, a new case report suggests otherwise. Read more about this red hot topic here.
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.
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.
We asked renowned myopia scientist and educator Professor Mark Bullimore about his paper on this topic, which clearly outlines that the benefits outweigh the risks with myopia control. Learn about why this analysis was explored, an overview of the paper and the take-home message for clinical practice, especially for childhood contact lens wear.
This cross-over study investigated the efficacy of highly aspherical lenslet (HAL) lenses to slow myopic progression for Vietnamese children. Switching from single vision to HAL lenses gave a slowing of myopia progression demonstrated by lesser axial elongation. Switching from HAL to SV did not demonstrate a myopia rebound effect.
