BOSTON – Innovega Inc.’s iOptik smart contact lens showed positive results in a phase 2 clinical trial involving subjects wearing the contacts with and without the company’s display eye wear.
Jennifer Fogt, OD, reported the study results for Innovega’s eMacula system, which pairs the smart contact lens with wide-field-of-view, high-resolution display eye wear, here at the American Academy of Optometry annual meeting.
The study’s abstract describes the iOptik as “an ultra-high Dk silicone elastomer contact lens designed with increased thickness to manage evaporation and a two-state gas-permeable polarizer and central lenslet for simultaneous distance vision and near-eye display vision.”
The researchers sought to assess best corrected distance acuity, the impact of the lenses on refractive correction, the ease of fusing the two images, the stability of the image and the ease of viewing 3D content, the company said in a press release.
Eleven women and four men, all normally sighted and with a mean age of 26.5 years, were fit with a plano lens with an 8.0 mm base curve and a lenslet with a filter polarization oriented at 180 degrees, according to the study. Fourteen wore +69 D lenslet power and one wore +60 D.
All subjects said they were able to view the 3D movie and reported mean scores of 7.67 for ease of obtaining fusion, 8.07 for ease of observing in 3D and 7.67 for stability of binocular display vision.
“The results of this small clinical evaluation of the Innovega contact lens-enabled wearable display system support the potential to provide users with normal visual acuity and with the ability to experience stable binocular near-eye display vision with a 3D experience," Fogt said in the press release.
Innovega co-founder and chief clinical and regulatory officer, Jerome A. Legerton, OD, MS, MBA, FAAO, said in the release that the results of this feasibility study “support the visual performance of the iOptik lens for regular vision correction and for viewing near-eye displays with binocular high-resolution 3D content.”
Innovega is jointly developing display eye wear and software for the visually impaired, according to the release. It is also investing in process engineering to lower the cost of its molded soft smart contact lenses, with the goal of commercializing a monthly disposable contact lens for the visually impaired and additional applications for normally sighted users.
