Iris Vascular Area Density-Based Preoperative Pain-Risk Screening and Intervention in Second-Eye Cataract Surgery

• Status: ACTIVE_NOT_RECRUITING
• Trial end date: 2025-12-31

Summary

This clinical trial aims to evaluate the effectiveness of pranoprofen or prednisolone acetate eye drops for pain management in patients undergoing second-eye surgery for age-related cataracts. Researchers will compare pranoprofen or prednisolone acetate eye drops with sodium hyaluronate eye drops to determine whether pranoprofen or prednisolone acetate eye drops can relieve intraoperative pain during second-eye cataract surgery.

Participants will:

1. Receive one drop in the operative eye at 2 hours, 1.5 hours, 1 hour, and 30 minutes before cataract surgery (pranoprofen, prednisolone acetate, or sodium hyaluronate)

2. Undergo cataract surgery and routine postoperative follow-up

3. Within 1 hour after surgery, provide a pain visual analog scale (VAS) score under the guidance of the investigator
