Peripheral vision function and reading speed were unaffected by highly aspherical (HAL) and slightly aspherical lenslet (SAL) spectacle lens designs compared to single vision lenses. Low contrast acuity was slightly reduced through the lenslet zone.
In this case, a colleague has his first experience with the new Essilor Stellest spectacle lens for childhood myopia, with discussion including when to change the prescription and when to stop treatment.
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).
Spectacle lenses which effectively control myopia progression are the next phase in widespread uptake of myopia management. Learn more about the Essilor Stellest lens, from myopia control to vision and visual function outcomes.
By using a wearable device to objectively monitor visual behaviour, this study found progression in young myopic children was correlated with less time outdoors, more time working at near for online learning and less time spent wearing their glasses.
Orthokeratology is effective for myopia control but is it suitable for a child with trichiasis and corneal staining? This case compiles the treatment suggestions for managing a young myopic patient with trichiasis from the Facebook community, with a focus on safety.
This study showed that multi-zone spectacle and contact lenses used for myopia control provide myopic defocus at far distances. At near, changes in accommodative lag, pupil miosis and spherical aberration in individuals may mean there are lesser amounts of myopic defocus and reduced image quality. However, all the lenses were still able to provide sufficient image clarity at near for typical size print.
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.
In myopic children, interventions to slow progression are warranted to prevent the development of high myopia and subsequent pathology and also to reduce the economic burden caused by uncorrected and pathologic myopia. This IMI Report describes the latest advice on preventing the development and progression of myopia – read the summary here.
This case is highlights that myopia management decision making includes much more than a child’s refraction. Learn how Keyur Patel involved the parent in the conversation and decision making, to determine the starting myopia management option for now, as well as considering the future.
