Effects of Trehalose, Sodium Hyaluronate and N-Acetyl Aspartyl-Glutamic Acid Artificial Tears on Ocular Surface Parameters in Glaucoma Patients Receiving Preserved and Preservative-Free Prostaglandins

Adjunctive treatment with preservative-free artificial tears containing trehalose, sodium hyaluronate, and NAAGA significantly improved tear film stability VF indexes, ocular surface signs and symptoms, and patient-reported QoL in POAG patients treated with prostaglandins, regardless of preservative status. Routine ocular surface optimization should be considered an integral component of comprehensive glaucoma management.
