This study reports one year results from an ongoing randomized clinical trial examining spectacle lenses with highly aspherical lenslet (HAL) or slightly aspherical lenslet (SAL) technology. The findings showed the HAL lens controlled refractive and axial progression by 60-70% and SAL by 30-40% over the first 12 months.
Providing spectacle correction is one of the cornerstones of primary eye care, and myopia controlling spectacles can both correct and control myopia. Here we explore the current myopia controlling spectacle lenses which have or are being commercialized, for which peer-reviewed publications are available – their design, presumed mechanism and comparative efficacy.
When prescribing myopia controlling contact lenses for children, daily disposables are the safest modality. Only spherical corrections are available, though, which can impact lens selection for children with astigmatism. The NaturalVue Multifocal contact lens is suggested for up to 2D of astigmatism, much higher than is typical for spherical CL designs. Is is ‘masking’ astigmatism, or ‘partially correcting’ it instead?
The NaturalVue Multifocal contact lens is a daily disposable which may slow myopia. It is recommended for low astigmatism, as is typical for spherical contact lenses, but its unique optical profile has led practitioners to ask if it can be fit to patients with higher levels of astigmatism. Read this case which highlights the dynamics of a young visual system, using the fitting guide and finding the best solution for a very high myope.
There are numerous reasons why contact lenses are beneficial for children, and the safety profile is high. Yet there are still barriers in the mind of the practitioner, parent and young patient to childhood CL wear. Here we address these often cited barriers, with the goal to support your clinical communication on the benefits and safety of contact lenses for kids, to move towards achieving a ‘yes’ from the parent and patient.
If a child is wearing spectacles or using atropine as their primary myopia control treatment, which contact lens should we choose for sports? Is a myopia controlling contact lens needed if it will only be for occasional wear? Here we discuss the options and clinical considerations based on the individual patient.
The value and importance of axial length measurement in myopia control is growing. As you offer myopia control to more patients, you could start to consider which instrument to use to measure axial length. How do ultrasound and interferometry instruments compare in accuracy? What about the new generation combination instruments? Here we address the practicalities of axial length measurement.
