Efficacy of 0.28% Sodium Hyaluronate Eye Drops in Patient With Moderate to Severe Dry Eye

This study aimed to evaluate the efficacy and safety of 0.28% preservative-free SH and 0.18% SH eye drops in patients with dry eye disease. Subjects diagnosed with dry eye disease and meeting the inclusion criteria (Ocular Surface Disease Index (OSDI) score ≥ 23, Fluorescein Tear Breakup Time (TBUT) \< 7 seconds were randomized into two groups. Group 1 (42 eyes) received 0.28% SH, and Group 2 (42 eyes) received 0.18% SH, both administered by a nurse. Measurements included tear osmolarity (TearLAB) before instillation and at 0,30 and 60 minutes post-instillation, recorded by a TearLAB specialist. Ophthalmologists assessed TBUT, ocular surface staining (Oxford grading scale), and the Schirmer I test before instillation and evaluated adverse reactions up to 60 minutes post-instillation. Subjects continued treatment for 30 days and were reevaluated during a second visit for OSDI scores, TBUT, the Oxford grading scale, and adverse events. Quality of life score were assessed at before and after treatment for 1 month.

Compare the Clinical Efficacy of 3% Diquafosol and 0.1% Hyaluronic Acid in Patients with Dry Eye After Trans-PRK

The prevalence of refractive ametropia is rising year by year. Refractive surgery has become the main approach for adults to correct refractive ametropia, and postoperative complications have aroused extensive attention from clinicians. Dry eye after refractive surgery is one of the postoperative complications, which is an important cause of affecting the postoperative visual quality and satisfaction of patients. It was reported that 3% diquafosol (DQS) and 0.1% hyaluronic acid (HA) can relieve dry eye symptoms. This study aims to compare the efficacy of 3% DQS and 0.1% HA in treating dry eye after Trans-PRK
