In this technology-driven age, the use of smart devices has caused near-work activities to consume the majority of our lives causing myopia to increase at alarming rates. With new technologies, tools, and medications, eyecare professionals are more equipped than ever to combat myopia progression.
Multifocal Contact Lens
Dual-action zone lenses (MiSight by Coopervision)
MiSight has been one of the top modalities used for myopia control in Europe and was recently released in the USA in March 2020. Not only is it a daily lens which means less risk of infection in children, but it has a unique dual focus design (see below), resulting in an even stronger treatment zone. A 3-year clinical study showed that it is superior in both refractive and axial length changes compared to its competitors, illustrating a reduced refractive rate of nearly 60% and axial elongation by 52%.1 The cost is approximately $110 for a 3-month supply for both eyes, making it one of the more affordable treatment options.
EDOF lenses (Mylo by mark’ennovy and NaturalVue by VTI Vision)
While the Mylo lens is not currently available in the USA, the NaturalVue lens is available at a cost of about $1000 for a year's supply. Both lenses use a unique extended depth of focus (EDOF) technology, which allows for a wider range of clearer vision without reducing the accommodative response. The latest study of the Mylo lens showed slightly larger absolute progression in both treatment and control groups. This study focused on patients of Chinese origin, whereas the MiSight and Biofinity MF study included children across multiple countries.2
The NaturalVue study showed comparable results to the Mylo lens; however, it was a retrospective study instead of a randomized clinical trial.3 Furthermore, the NaturalVue lens has been noted to be a little more uncomfortable than other multifocal contact lens and takes a few days to adapt to the optics. New data has been recently been added which shows continual minimization of the progression of myopia, with the amount of refractive change on average less than 0.125D and approx. 0.10 mm of axial length growth per year.
