Design and Clinical Evaluation of a Smartphone-based Low Vision Enhancement System
In Brief
A clinical study evaluating Virtual bioptic magnification with large field of view and Full field magnification with small field of view for Low Vision. Completed, enrolled 88 participants across 1 site.
Detailed Summary
The primary objective is to compare the effectiveness and adverse side-effects of the virtual bioptic telescope and virtual projection screen in a new head-mounted video-based low vision enhancement system (LVES) with a wide field of view to currently employed specifications for head-mounted video display low vision enhancement technology. Secondary objectives are to acquire qualitative information from patients to evaluate the functioning of the system, to optimize system features and operations, and to assess the value patients place on system features, functions, and operating parameters relative to those of current technology. Investigators will conduct a comparative effectiveness study to determine if the novel vision enhancing features of LVES 2 provide low vision patients with benefits superior to those provided by existing technology.

Interventions
The intervention device will have a larger field of vision than the legacy device and the intervention device will also have a virtual bioptic telescope mode not found on the legacy device. The user will be able to adjust the size of the virtual bioptic telescope and the amount of magnification with a touch pad on the side of the head-mounted display (HMD).
Comparison intervention with user-controlled full field magnification with a smaller field size shared by legacy head-mounted devices. User can control amount of magnification
