Acupuncture is as effective as artificial tear therapy (ATC) at reducing the symptoms of xerophthalmia (dry eyes), and the effects of acupuncture last longer. Chinese researchers compared 44 patients who were divided into two groups; one received ten sessions of acupuncture, while the other received ATC over a 21-day period. One hour after treatment, no significant difference in symptom scores could be found between the two groups. Three weeks after completion of treatment, however, the reduction in symptom scores for the acupuncture group was significantly greater than that of the ATC group.
