Effect of sodium hyaluronate (0·1%) on break-up time (NIBUT) in patients with dry eyes

Abstract

We evaluated the effect of 0·1% sodium hyaluronate (unpreserved) in 10 patients with dry eyes. The precorneal tear film break-up time was assessed by the non-invasive technique, and the severity of symptoms was recorded before and after treatment on a 0 to +3 scale. It was found that the tear film stability was significantly increased (p<0·05) in eyes treated with sodium hyaluronate. The symptoms of grittiness and burning were also significantly alleviated in the treated eyes.
