PURPOSE: This study aimed to compare the effectiveness of eye drops containing a combination of sodium hyaluronate and trehalose and sodium hyaluronate for the treatment of corneal cross-linking and epithelial healing.
METHODS: This study included 46 eyes of 23 keratoconus patients who underwent corneal cross-linking on both eyes. Unpreserved trehalose 30 mg/mL and sodium hyaluronate 1.5 mg/mL (Thealoz Duo®; Thea, France) were applied six times a day on one eye of each patient and unpreserved sodium hyaluronate 0.15% (Eye Still®; Teka, Inc., Istanbul) was applied on the other eye. Patients were examined daily until complete re-epithelialization. Postoperative examinations to assess the measured size of epithelial defect were performed using slit-lamp biomicroscopy.
RESULTS: The study included 23 patients (13 females and 10 males) with a mean age of 20.9 ± 10.3 years. Corneal epithelial healing time after cross-linking was 2.3 ± 1.2 days for the trehalose and sodium hyaluronate group and 3.8 ± 2.9 days for the sodium hyaluronate group (p=0.03).
CONCLUSION: The application of eye drops containing the combination of trehalose and sodium hyaluronate resulted in faster corneal re-epithelialization following corneal cross-linking than that of eye drops containing sodium hyaluronate alone.
