Comparison of the Efficacy of Two Lipid Emulsion Eyedrops in Increasing Tear Film Lipid Layer Thickness

Abstract

The application of a lipid emulsion eyedrop will increase LLT and benefit patients with deficient lipid layers who experience dry eye symptoms. Although both products are lipid emulsions, one drop of Soothe essentially doubled LLT and provided a mean increase in LLT that was 2.5 times greater than that of Refresh Dry Eye Therapy.
