Brief summary
One dose group of 0.004% was used.
Detailed description
One dose group of 0.004% was used. The whole study includes two stages: pre-test and formal test.
Interventions
On the 1st postoperative day (Day1), ZKY001 eye drops were dropped into the experimental eyes (the operative eyes were taken as the experimental eyes). ZKY001 eye drops were given at 8:00 am ±1h from Day1 to Day5. 4 times a day, 1 drop each time, recommended interval of 4 to 6 hours. Day6 was administered at 8:00 am ±1h, and ZKY001 eye drops were dropped into the test eye (the surgical eye was taken as the test eye). Day6 was given only once, 1 drop each time.
