A randomised controlled trial on the effect of a virtual three-dimensional eye model on patient satisfaction

Patients forget up to 80% of verbal communication. Visual aids improve understanding and information retention. A virtual, three-dimensional, interactive eye model (the One Right Eye model) is a new tool for eye care providers. The utility of three-dimensional models has been studied in other specialities, but never in ophthalmology.
This study investigates whether the One Right Eye model improves patient satisfaction and understanding during ophthalmic outpatient appointments.
In a single-centre, open-label, randomised controlled trial, 92 patients were divided into two groups: a control group receiving a standard face-to-face consultation (n = 45) or an interventional group receiving the same consultation supplemented with a virtual eye model demonstration (n = 47). Key outcomes included patient satisfaction, understanding of their ocular condition, and rating of their explanation from their doctor.
The interventional group rated their explanation from their doctor statistically significantly higher than the control group (89% versus 69% ‘very good’, p = 0.03). Trends also indicated improved understanding (81% versus 62%, ‘completely understood’, p = 0.05) and greater satisfaction (83% versus 69% ‘very satisfied’, p = 0.12) in the interventional group compared to controls. While the latter two results did not reach statistical significance, the data suggest clinical improvements.
The virtual three-dimensional eye model improved patients’ perception of their explanation from their doctor and likely improved patient satisfaction and understanding of their ophthalmic condition. The One Right Eye, a virtual eyeball model, shows promise to enhance ophthalmic communication.
