Summary

This study assessed the effect of one month of use of preservative-free artificial tears (Systane Ultra UD, Alcon) on symptomatology related to digital eye strain (DES), visual task performance, and tear film stability in visual display terminal users.

Detailed description

Visual display terminal users (\>4h/day) with DES (CVSS17 score: ranged 29 to 42) and dryness (OSDI score: ranged 13 to 24) symptomatology were prescribed with preservative-free artificial tears (Systane Ultra UD, Alcon) four times a day for one month collecting OSDI and CVSS17 questionnaires in four visits \[screening (Day -7), initial (Day 0), one week (Day 7) and one month (Day 30)\]. Blink rate and number of eye fixations (collected with eye-tracker) in six simple computer tasks and out-loud reading speed were determined before and after performing all tasks on the computer. Tear film stability and ocular parameters were also measured.
