Evaluation of the Performance of an Ocular Surface Modulator Containing ST-Lysyal Versus Hyaluronic Acid Eyedrops in Patients with Dry Eye Disease: A Pilot Study.

Introduction: Dry eye disease (DED) is a multifactorial condition of the ocular surface, primarily treated with tear substitutes, which do not fully restore natural tear functions. In this pilot study, we tested the hypothesis that T-Lysyal (T-Lys) improves symptoms and signs in patients with DED. Additionally, we provide a literature overview on the effects of T-Lys in ophthalmology and non-ophthalmology conditions to elucidate its mechanisms of action.
