Effect of 0.15% Preservative-free Sodium Hyaluronate on Dry Eye Disease after Femtosecond Laser-assisted Cataract Surgery

Purpose: The efficacy of using preservative-free 0.15% sodium hyaluronate eyedrops for dry eye disease after femtosecond laser- assisted cataract surgery (FLACS) was evaluated. Methods: This prospective randomized study conducted on patients with who were scheduled FLACS among those Tear Film & Ocular Surface Society Dry Eye Workshop II Levels 1 and 2. In total, 37 eyes to the treatment group (n = 19) or control 18). Corneal conjunctival fluorescein staining (CFS), tear breakup time (TBUT), Schirmer I test (SIT) value, ocular surface index (OSDI), meibomian gland evaluation result, lipid layer thickness evaluated all patients, preoperatively at 3 months postoperatively. Results: group, OSDI CFS scores significantly lower postoperatively than baseline, but TBUT SIT values increased. shorter decreased compared meibum quality aggravated month baseline. improved from baseline months. increased in postoperative Meibomian showed clinically better results There no significant differences corneal CFS, thickness, other parameters between groups. Conclusions: Preservative-free effective improving symptoms film stability FLACS.
