Purpose : A new augmented reality (AR) spectacle or head mounted device, Eye-01, has been designed to meet multiple needs at distance, intermediate, and near. The purpose of the study is to explore the capabilities of Eye-01 with AMD patients when performing tasks such as continuous text reading and other activities of daily life. Effectiveness was measured using the MNRead and a Timed Instrumental Activities of Daily Life (TIADL) inventory.

Methods : The study was a single arm, crossover study with 14 subjects who have age related macular degeneration. Mean age was 84 (74-90) and mean best corrected acuity was 20/145 (20/70 to 20/250). Reading performance using the MNRead was compared between near correction alone and the Eye-01 device set at 3X magnification and then with various settings. A TIADL was used to compare time to complete tasks at near, intermediate, and distance. Two study visits with the first visit including tests of visual function as well as training with the Eye-01. A second visit included a review of training and then outcomes with the Eye-01.

Results : Mean CPS improved from 0.96 logMar with near correction alone to 0.71 logMar with the Eye-01 at 3X magnification. Improvement ranged up to 7 lines. Subjects who noted more difficulty with reading items on the LV VFQ-48 tended to be older and although they improved with the Eye-01, younger subjects improved to a greater degree. However, with task performance, there was no relationship to age. All subjects performed better on tasks with the device compared to without (p=0.004) and especially with the enhanced contrast (Britext) feature (p<0.0001). The mean time to complete TIADL tasks was improved (308s reduced to 171s) with the Eye-01 and Britext (p<0.001). With spectacles alone, nine of the subjects were unable to perform any of the tasks (e.g., maximum time score of 360s) but with the Eye-01, all subjects were able to complete at least one if not all three tasks. The mean time to train subjects on all features took 41 minutes.

Conclusions : As an augmented reality device, the Eye-01 improved the ability to access small print and to perform timed daily living tasks at all viewing distances when compared to standard near correction alone in a group of subjects with moderate visual impairment from AMD. Regardless of age or severity of impairment, a specific training protocol was effective in introducing subjects to the various features of the Eye-01.
