Brief Summary
|
Dry eye disease (DED), also known as dry eye syndrome (DES), is a multifactorial disorder of the ocular surface characterized by instability of the tear film, leading to symptoms of dryness, irritation, and visual disturbances. It is further associated with increased tear osmolarity and inflammation, resulting in damage to the ocular surface. The International Dry Eye Workshop (TFOS DEWS II) has defined DED as a condition of tear film instability and osmolarity, which can be classified into two primary subtypes: aqueous-deficient dry eye (ADDE), characterized by insufficient tear production, and evaporative dry eye (EDE), resulting from excessive tear evaporation, often due to meibomian gland dysfunction (MGD) or environmental factors. To evaluate the comparative efficacy of XanMax® 2004 oral soft gel capsules (containing lutein and zeaxanthin 20 mg in the ratio of 5:1), with that of placebo soft gel capsules in adult subjects with dry eye symptoms Building on this evidence, the present study aims to evaluate the efficacy and tolerability of XanMax® 2004, a novel formulation containing lutein and zeaxanthin, in adult subjects with dry eye symptoms. This randomized, double-blind, placebo-controlled clinical study will assess the impact of supplementation on tear film stability, tear production, and symptom alleviation, providing insights into the potential benefits of lutein and zeaxanthin in addressing the growing burden of DED. |
