Outcome Measures

Primary Outcome Measures

  1. Ocular Surface Disease Index questionnaire [0 day preoperatively]

    Ocular Surface Disease Index questionnaire were included 12 questions,and each was rated from 0-4

  2. Ocular Surface Disease Index questionnaire [1 day postoperatively]

    Ocular Surface Disease Index questionnaire were included 12 questions,and each was rated from 0-4

  3. Ocular Surface Disease Index questionnaire [1 week postoperatively]

    Ocular Surface Disease Index questionnaire were included 12 questions,and each was rated from 0-4

  4. Ocular Surface Disease Index questionnaire [1 month postoperatively]

    Ocular Surface Disease Index questionnaire were included 12 questions,and each was rated from 0-4

  5. Ocular Surface Disease Index questionnaire [3 months postoperatively]

    Ocular Surface Disease Index questionnaire were included 12 questions,and each was rated from 0-4

  6. Tear Breakup Time [0 day preoperatively]

    Tear Breakup Time was performed to assess tear film stability

  7. Tear Breakup Time [1 week postoperatively]

    Tear Breakup Time was performed to assess tear film stability

  8. Tear Breakup Time [1 month postoperatively]

    Tear Breakup Time was performed to assess tear film stability

  9. Tear Breakup Time [3 months postoperatively]

    Tear Breakup Time was performed to assess tear film stability

  10. Schirmer test with anesthesia [0 day preoperatively]

    The Schirmer test was performed by inserting a test strip

  11. Schirmer test with anesthesia [1 week postoperatively]

    The Schirmer test was performed by inserting a test strip

  12. Schirmer test with anesthesia [1 month postoperatively]

    The Schirmer test was performed by inserting a test strip

  13. Schirmer test with anesthesia [3 months postoperatively]

    The Schirmer test was performed by inserting a test strip

Secondary Outcome Measures

  1. Subjective symptoms [0 day preoperatively]

    Subjective symptoms evaluation related to 11 ocular symptoms ,and each was graded as follows:0 never、1 occasional、2 often、3 always

  2. Subjective symptoms [1 day postoperatively]

    Subjective symptoms evaluation related to 11 ocular symptoms ,and each was graded as follows:0 never、1 occasional、2 often、3 always

  3. Subjective symptoms [1 week postoperatively]

    Subjective symptoms evaluation related to 11 ocular symptoms ,and each was graded as follows:0 never、1 occasional、2 often、3 always

  4. Subjective symptoms [1 month postoperatively]

    Subjective symptoms evaluation related to 11 ocular symptoms ,and each was graded as follows:0 never、1 occasional、2 often、3 always

  5. Subjective symptoms [3 months postoperatively]

    Subjective symptoms evaluation related to 11 ocular symptoms ,and each was graded as follows:0 never、1 occasional、2 often、3 always

  6. Fluorescein Staining [0 day preoperatively]

    The corneal surface was divided into four regions, and each region was scored as follows: 0, no staining; 1, between one and three dots; 2, less than five dots; and 3, bulk or strip staining. The four regions scores were then added to obtain a final score for the eye

  7. Fluorescein Staining [1 week postoperatively]

    The corneal surface was divided into four regions, and each region was scored as follows: 0, no staining; 1, between one and three dots; 2, less than five dots; and 3, bulk or strip staining. The four regions scores were then added to obtain a final score for the eye

  8. Fluorescein Staining [1 month postoperatively]

    The corneal surface was divided into four regions, and each region was scored as follows: 0, no staining; 1, between one and three dots; 2, less than five dots; and 3, bulk or strip staining. The four regions scores were then added to obtain a final score for the eye

  9. Fluorescein Staining [3 months postoperatively]

    The corneal surface was divided into four regions, and each region was scored as follows: 0, no staining; 1, between one and three dots; 2, less than five dots; and 3, bulk or strip staining. The four regions scores were then added to obtain a final score for the eye
