Outcome Measures

Primary Outcomes (2)

  • visual analog scale(VAS)

    The VAS pain score provides an intensity score of the pain experienced. The VAS allows the patient to self-rate his or her pain on a 0 to 10 horizontal grading scale of subjective pain assessment with 0 as "no pain at all" and 10 being "the most severe intolerable pain I have ever experienced."

    Change from Baseline VAS at 10 days

  • present pain intensity index(PPI)

    The PPI scale is a measure of the magnitude of pain experienced by an individual and is a six-point verbal rating scale that indicates overall pain intensity and includes six levels (0, none; 1, mild; 2, discomforting; 3, distressing; 4, horrible; and 5, excruciating). Higher numbers indicate more severe pain.

    Change from Baseline PPI at 10 days

Secondary Outcomes (5)

  • corneal epithelium healing(CEH)

    Change from Baseline corneal epithelial defect at 10 days

  • Inflammation Evaluation by temporal conjunctival hyperaemia index (TCHI)

    Change from Baseline TCHI at 10 days

  • Symptoms Evaluation by ocular symptom scores(OSS)

    Change from Baseline OSS at 10 days

  • psychological state changes of depression was evaluated with Self-rating Depression Scale(SDS)

    Change from Baseline SDS at 10 days

  • psychological state changes of anxiety was evaluated with Self-rating Anxiety Scale(SAS)

    Change from Baseline SAS at 10 days
