Outcome Measures

Primary Outcomes (1)

  • The change of corneal epithelial defect area on Day 3 compared with that on baseline will be calculated by the grid method

    Subjects will undergo fluorescein staining of the cornea, slit-lamp examination and photography (8:00 ±1h) before first administration on Day1(the first day after surgery,baseline),Day3 (the third day after surgery).After slit-lamp photography was scanned by the scanner, image pro plus software was used to scale the photo to the same size as the test eye, and then the grid method was used to calculate the area of the corneal defect in the photo. Improvement in epithelial defect area = defect area on baseline - defect area on Day3

    Day 3, 8:00 am±1hour

Secondary Outcomes (5)

  • The subject's symptoms and signs will be evaluated on the General Arbitroid

    Day 3, Day6 、Day15 8:00 am±1hour

  • Scoring with D6 and D15 corneal fluorescein staining

    Day6 、Day15 8:00 am±1hour

  • The improvement rate of corneal epithelial defect area on Day 3 postoperation after surgery compared with that at baseline (Day1 postoperation ) will be calculated by the grid method

    Day 3, 8:00 am±1hour

  • The change of corneal epithelial defect area on Day 2、Day4、Day5 compared with that on baseline(Day 1) will be calculated by the grid method

    Day 2、Day4、Day5 8:00 am±1hour

  • The incidence of reexfoliation of corneal epithelium was observed

    Day 3, Day4,Day5,Day6,Day15±2 8:00 am±1hour

Study Arms (3)

PLACEBO COMPARATOR

Placebo group C: ZKY001 simulated eye drops .4 times a day,1 drop every time, continuously administered for 14±2 days ZKY001 simulated eye drops will be directly dripped into the test eye (the surgical eye was taken as the test eye).
