Innovega’s iOptik/eMacula system improved visual acuity and comfort in patients with low vision, according to a study presented at the virtual Association for Research in Vision and Ophthalmology annual meeting.
“The results of the evaluation of the Innovega contact lens-enabled wearable display system support the potential to provide the wide field of view required when magnifying content along with high resolution and control of brightness and contrast for visually impaired users,” co-investigator and associate professor at The Ohio State University College of Optometry, Bradley Dougherty, OD, said in a press release from Innovega.
Innovega’s system combines spectacle-mounted micro-displays and smart contact lenses to magnify and modify images for the user, according to the study abstract
San-San Cooley, OD, of Ohio State, and colleagues evaluated nine participants with low vision as they wore their habitual correction, used low vision devices and wore the Innovega system while performing daily tasks such as reading, using a smartphone and distance viewing.
Visual acuity improved from 20/100 to 20/20, but there was no significant difference in contrast sensitivity or reading speed, according to the study.
Subjects reported a mean comfort score of 7.1 + 1.6 on a scale of 1 to 10. In addition, three-fourths of the participants said they “felt the device would likely improve performance on activities of daily living and increase independence.”
