This study evaluated the visual performance and optical quality of three lenslet design spectacle lenses. While all degraded visual performance in some capacity, the concentric design (highly and slightly aspherical) lenses generally had a significantly lower impact on both acuity and contrast than honeycomb configuration (HC).
This cohort study from Australia reported a 14% incidence (onset) of myopia between ages 20 and 28, with almost 40% of myopes progressing by at least 0.50D. Axial length increase was also demonstrated. Risk factors were related to ethnicity, sex, sun exposure and parental myopia but not education level. This data advocates for active myopia management throughout the 20s.
With growing popularity of contact lens wear in children, the scrutiny of their safety increases. This 3-year investigation of adverse events related to monthly disposable soft contact lens wear in 7- to 11-year-old participants provides reassurance to parents and eye care practitioners that contact lenses can be worn safely in this age group.
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.
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.
This study examines the effect that dual focus contact lenses have on accommodation and defocus during near viewing, and the results provide clues towards understanding the myopia control mechanism of these contact lenses.
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.
This abstract reported on the association between myopia and dry eye disease in teenagers. Interestingly, dry eye disease and reduced break up time was associated with higher myopia, but photophobia and pain were not.
Increasing power in a myopia control treatment zone of a multifocal soft contact lens can increase myopia control efficacy but negatively impact vision. This study is the first optical characterization of a novel design to improve this relationship between treatment zone power and vision quality.
With increasing use of axial length to monitor myopia progression, the ratio of refractive error change to axial elongation has important clinical implications. This systematic review determines this ratio and explores factors that influence it.
