Outcome Measures

Primary Outcomes (6)

  • an Ocular Surface Disease Index (OSDI) Questionnaire That is Related to Dry Eye Severity.

    The OSDI questionnaire consists of 12 questions that evaluate subjective symptoms related to dry eye and vision The score ranges were between 0 and 100 scores and the higher scores represent a worse outcome.

    12 weeks

  • Schirmer I Test Without Anesthesia That is Related to Dry Eye Severity.

    Schirmer paper strips were placed into the temporal one third of the lower conjunctival sac for 5 min and the wetness on the strips was measured.

    12 weeks

  • Changes in HOAs After Blinking That is Related to Dry Eye Severity.

    Corneal HOAs and serial measurement of ocular total HOAs were evaluated using a KR-1W wavefront analyzer (Topcon Medical System, Inc., Tokyo, Japan). Serial measurement of total ocular HOAs was measured every second for 10 s after complete blinking in continuous measurement mode. The difference between the fifth and first HOA was used to evaluate the tear film instability.

    12 weeks

  • Tear Break-up Time (TBUT) That is Related to Dry Eye Severity.

    TBUT was assessed by instillation of a drop of 2% sterile fluorescein into the conjunctival sac and recording the interval between the last complete blink and the first appearance of a dry spot or disruption of the tear film.

    12 weeks

  • Corneal Fluorescein Staining That is Related to Dry Eye Severity.

    Ocular surface damage was assessed by the National Eye Institute (NEI) workshop grading system, and corneal fluorescein staining was evaluated. Instillation of fluorescein in both eyes. After 1 or 2 full blinks, the intensity of staining of both cornea was scored. According to the National Eye Institute (NEI) workshop grading system, the cornea was divided into five sections. The minimum staining score was 0 and the maximum staining score was 15 points (up to 3 points for each section). 0 : best score (no corneal damage) 15 : worst score (severe corneal damages)

    12 weeks

  • Lissamine Green (LG) Conjunctival Staining That is Related to Dry Eye Severity

    Ocular surface damage was assessed by the National Eye Institute (NEI) workshop grading system, and conjunctival LG staining were evaluated. Instillation of 1% lissamine green in both eyes. After 1 or 2 full blinks, the intensity of staining of both medial and lateral bulbar conjunctiva was cored. According to the National Eye Institute (NEI) workshop grading system, the conjunctiva was divided into six sections. The minimum staining score was 0 and the maximum staining score was 18 points (up to 3 points for each section). 0 : best score (no conjunctival damage) 18 : worst score (severe conjunctival damages)

    12 weeks

Secondary Outcomes (2)

  • Grades of Anterior Chamber Cells.

    12 weeks

  • Number of Participants Who Stop Using the Eye Drops Due to Drug-related Discomfort
