The study began with the administration of online surveys to 1,000 participants with dry eye disease, residing in Europe.
Researchers assessed the severity of symptoms among the participants.
“All participants completed the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25), with six additional questions (items A3–A8), and the EuroQol 5 dimensions 5 levels,” the findings state.
The findings led to negative effects on visual function and work productivity among the participants with dry eye disease.
“Dry eye disease (DED) symptoms were associated with negative effects on visual function, activities and work productivity, whereas worse DED symptoms had a greater impact on vision-related QoL and work productivity,” the study concluded.
