Conditions

Myopia

Brief summary

Acucela Inc. intends to develop a medical device to significantly halt or reverse myopic progression, which is a significant public health concern across the world, especially in Asian demographics. Acucela is working towards a spectacle-like device (eSPECs), which will have a clear zone for unimpeded central visual tasks and a periphery that provides defocus in order to alter retinal physiology leading to myopia regulation. This study will establish the changes seen during a proof-of-concept that projected defocus in the periphery utilizing a wearable device will stimulate physiological changes similar to those in the literature.

Interventions

DEVICEActive projection of defocused image in the peripheral visual field (eSpecs, Acucela Inc.)

For the right/test eye, a defocused image is projected onto the peripheral retina while the subject views a distant, in-focus image

DEVICENo Active projection of defocused image in the peripheral visual field (eSpecs, Acucela Inc.)

For the left/control eye, no image is projected onto the peripheral retina. The subject views a distant, in-focus image.
