Treating dry eye after laser eye surgery
Part of Eyes & vision clinical trials.
This trial compares two eye drops (diquafosol 3% and hyaluronic acid 0.1%) for treating dry eye that occurs after a specific laser eye surgery called Trans-PRK. If you qualify, you would receive one of these treatments to help keep your eyes comfortable and healthy after the procedure.
