Prednisolone Acetate Eye Drops for Pain Intervention in Second Eye Cataract Surgery

This study aims to evaluate the efficacy, safety, and potential mechanisms of prednisolone acetate eye drops for pain management in patients undergoing second-eye surgery for age-related cataracts. Researchers will compare prednisolone acetate eye drops to sodium hyaluronate eye drops to see if prednisolone acetate eye drops work to relieve intraoperative and postoperative pain during second-eye cataract surgery. Participants will: 1. Receive prednisolone acetate eye drops or sodium hyaluronate eye drop four drops within 2 hours before cataract surgery 2. Finish cataract surgery and routine postoperative follow-up 3. Pain questionnaire completed after cataract surgery
