Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Subjects with dry eye are enrolled at two ophthalmic centers and randomly assigned to a laser acupuncture group and control group under conventional treatment with artificial tears. The effects of laser acupuncture therapy for patients with dry eye are investigated.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Objective: Dry eye is a common ophthalmologic disorder causing ocular discomfort in daily life. The investigators aim to investigate the effects of laser acupuncture therapy for patients with dry eye.

Methods: 200 subjects with dry eye are enrolled at two ophthalmic centers and randomly assigned to a laser acupuncture group and control group under conventional treatment with artificial tears. The subjects are treated at acupoints including BL2, TE23, ST2, LI4, ST36, and GB37 using verum or sham laser acupuncture during 3 sessions per week. After 4 and 12 weeks of treatment, the differences in the Tear film break-up time, Schirmer test, visual analogue scale, Ocular Surface Disease Index of the patients are analyzed, and compared between the laser acupuncture and control groups using paired t-test and one way ANOVA.
