Objective: To assess the effect of a lubricant emulsion upon symptoms, tear film instability, and eye surface damage in patients with dry eye associated to the computer vision syndrome (CVS). Materials and Methods: This is a case series study, which analyzed the effect of a lubricant emulsion in patients with CVS-associated dry eye. Symptoms were assessed using the Ocular Surface Disease Index (OSDI) questionnaire, tear film instability was assessed measuring the tear film breakup time (TFBT) using fluorescein, and eye surface damage was assessed using the Oxford Schema. Measurements were performed before and after 30-day therapy. Results: Ninety-six patients were assessed, their age was 25.9 7.2 (18 -44) years, and 62.9% were female. TFBT had a 4.3 2.6 second increase (p<0.001) after therapy. This increase was clinically important in 70.8% of all cases. The OSDI score had an average 15.8 7.4 point reduction after therapy (p<0.001), and this reduction was clinically important in 95.8% of all cases. Before therapy, 21.9% subjects had damage on the eye surface (Oxford 1/5), which was solved at the end of therapy (p<0.001). Conclusions: In patients with CVS-associated dry eye, the studied emulsion led to clinically significant improvement in the three variables that were assessed, particularly in symptom alleviation. Eye surface damage was non-frequent and mild in these patients, and it got solved after one month with therapy.
