Can low-concentration atropine delay myopia onset in pre-myopic children?

The LAMP2 study explored the efficacy of low-concentration atropine to delay the onset of myopia in at-risk children. The results found there was no significant difference between 0.01% atropine and the placebo, but 0.05% atropine was able to reduce myopia incidence and speed of myopic progression for pre-myopes.

Which age group might benefit most from orthokeratology?

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.

Combining DIMS spectacle lenses with atropine 0.01% in European children

This prospective observational study found that DIMS spectacle lenses, atropine 0.01% and the combination of the two all showed robust efficacy for myopia control in European children. The combination treatment showed slightly better refractive control than the mono-therapies, but axial length growth was similar in all treatment groups.

How does NaturalVue Multifocal 1 Day perform long-term for myopia?

This retrospective cohort analysis showed that NaturalVue Multifocal 1 Day contact lens wear appears to result in a mean refractive myopia progression of less than 0.25D per year, based on available data. Some limited axial length data was also presented.

Can we predict success with orthokeratology?

This study investigated the accuracy of using pre-treatment axial elongation and changes in refractive sphere in predicting myopia control success in orthokeratology. Axial length was the more accurate method for categorisation of slow, moderate or rapid progression, and fast progressors benefited the most from ortho-k wear.

Time spent outdoors improves success with MiSight 1 day

This paper identified time spent outdoors as the key factor in predicting better myopia control outcomes in children wearing with MiSight 1 day contact lenses. Other factors which weren’t predictive included age, refraction, binocular vision findings, pupil size and time spent at near.

Myopia control and no rebound with Highly Aspherical Lenslet spectacles

This cross-over study investigated children wearing highly aspherical lenslet (HAL) spectacle lenses versus single vision spectacles over three six-month periods. The HAL lenses showed consistent myopia control efficacy and no rebound effect when discontinued over one of the six-month periods.

Atropine 0.01% combined with orthokeratology over two years

Atropine 0.01% combined with orthokeratology slows axial elongation to less than 0.1mm/year over two years in Chinese children aged 6-11 years. This is the equal-longest study on this topic and first to measure potential mechanisms of pupil size and choroidal thickness. The largest effect of the combination occurred in the first 6 months.
