Abstract [en]

This study aimed to compare  the artificial tears Systane Ultra with Add1 and their performance in NITBUT (Non Invasive Tear Break Up Time). 20 participants between 21-29 years were divided into two groups , one group received Systane Ultra and the other Add1. Once each participant filled out an OSDI survey NITBUT was measured. First without any Artificial tears and then 5, 10, 15 , 20, 30 , 45 and 60 minutes after instillation. The Systane Ultra group and Add1 group differs in this study, however, no significant difference ( P = 0.055 ) in amplitude of NITBUT was obtained. Over time there is no significant difference (P > 0.05). The two drops perform equal at all times.

There are advantages to using an instrument like Bon Sirius, for example, to avoid the bias of the observer. This study can be considered as an experimental study for future studies in the field.
