Treatment groups
Trial outcomes
Primary outcomes
OSDI
The Ocular Surface Disease Index (OSDI) includes 12 questions grouped by poor symptoms and visual disturbance (light sensitivity, eyes feel gritty, painful or sore eyes, blurred vision or poor vision); visual function/tasks (problems when reading, driving at night, working on a computer or watching TV); and environmental questions (problems in windy conditions, places/ areas with low humidity or areas that are air conditioned). The scores range from 0 to 100. On the basis of the score, the patient's symptoms can be categorized as normal (0-12), mild dry eye (13-22), moderate dry eye (23-32), or severe dry eve (33-100).
Secondary outcomes
TBUT
Tear breakup time (TBUT) is a clinical test used to assess for evaporative dry eye disease. To measure TBUT, fluorescein is instilled into the patient's tear film and the patient is asked not to blink while the tear film is observed under a broad beam of cobalt blue illumination. The TBUT is recorded as the number of seconds that elapse between the last blink and the appearance of the first dry spot in the tear film, as seen in this progression of these slit lamps' photos over time. A TBUT under 10 seconds is considered abnormal.
Schirmer
The Schirmer test is objectively used to measure tear secretion without anesthetized. A healthy eye should wet more than 10 mm of the standard filter strip in 5 minutes. The travel rate along the test strip is proportional to the tear production rate.
SF-36
36-Item Short Form Health Survey (SF36) measures quality of life on the basis of eight dimensions or concepts that are frequently used in health studies. These eight dimensions are estimated from eight subscales that examine physical functioning (SF36-PF), role functioning-physical (SF36-RP), bodily pain (SF36-BP), general health (SF36- GH), vitality (SF36-VT), social functioning (SF36-SF), role functioning-emotional (SF36-RE), mental health (SF36-MH) and reported health transition (SF36-HT). Item responses were ranaina from 0 (best) to 100 (worst), with hiaher scores are equivalent to areater severity of better quality of life.
SAS
The SAS is a 20-item self-report instrument designed to assess anxiety symptoms in clinical and research settings. This scale ranges from 20 to 80, with lower scores indicating better self-reported mental health and fewer anxiety symptoms.
