What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Non-invasive tear break-up time
Time Frame: Day-0 (baseline), 2-week, 4-weeks

Changes in non-invasive initial tear film breaking time will be assessed using the Keratograph 5M (Oculus, Germany) topographer.

Three sequentially readings will be captured, and the median value will be included in the final analysis. The median value will be recorded.

Day-0 (baseline), 2-week, 4-weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Conjunctival hyperemia (RS score)
Time Frame: Day-0 (baseline), 2-week, 4-weeks
Conjunctival hyperemia (RS score) will be assessed by keratograph image (Oculus, Germany) of 1156*873 pixels, redness score (RS) (accurate to 0.1 U) was displayed on the computer screen that ranged from 0.0 to 4.0.
Day-0 (baseline), 2-week, 4-weeks
Quality of meibum grade
Time Frame: Day-0 (baseline), 2-week, 4-weeks

Meibum quality will be assessed under a slit-lamp:

Five meibomian gland in the middle parts of the eyelid will be assessed using a scale of 0 to 3 for each gland (0 represented clear meibum; 1 represented cloudy meibum; 2 represented cloudy and granular meibum; and 3 represented thick, toothpaste like consistency meibum).

Day-0 (baseline), 2-week, 4-weeks
Expressibility of meibum grade
Time Frame: Day-0 (baseline), 2-week, 4-weeks

Meibum expressibility will be assessed under a slit-lamp:

Eight meibomian glands in the middle part will be evaluated on a scale of 0 to 3 (0 denoted that all glands expressible; 1 denoted that 3 to 4 glands expressible; 2 denoted those 1 to 2 glands expressible; and 3 denoted that no glands were expressible). The overall score was computed using the mean scores of these eight glands.

Day-0 (baseline), 2-week, 4-weeks
Conjunctivocorneal epithelial staining grade
Time Frame: Day-0 (baseline), 1-week, 2-weeks

Conjunctivocorneal epithelial staining will be assessed under a slit-lamp:

Conjunctivocorneal epithelial staining will be assess corneal and conjunctival epithelium damage. Double vital staining approach with two microliters of a preservative-free solution containing 1% lissamine green and 1% sodium fluorescein will be instilled in the conjunctival sac.

The eye will be sectioned into three equal pieces (temporal conjunctiva, cornea, and nasal conjunctiva). Each region receives a maximum staining score of three points and a minimum of zero points. The combined scores from all three parts were then recorded on a scale ranging from 0 (normal) to 9 (severe).

Day-0 (baseline), 1-week, 2-weeks
Tear Film Lipid Layer
Time Frame: Day-0 (baseline), 2-week, 4-weeks
Tear Film Lipid Layer interferometry will be assessed using DR-1 (Kowa, Nagoya, Japan).
Day-0 (baseline), 2-week, 4-weeks
OSDI Score
Time Frame: Day-0 (baseline), 2-week, 4-weeks
Chinese translated, and validated OSDI (Allergan Inc, Irvine, USA) version will beused to assess and quantify DE symptom. The 12 items of the questionnaire can be tabulated into a score that ranges from 0 (no symptoms) to 100 (severe symptoms) points
Day-0 (baseline), 2-week, 4-weeks
