Purpose: The objective of this review was to assess the effectiveness of acupuncture as a treatment option for treating the condition of dry eye.
6 comparison studies were done. Three compared the effects of acupuncture with artificial tears in patients with dry eye. An analysis of the data showed that acupuncture improved signs of dry eye significantly more than artificial tears did. The other three studies compared the effects of acupuncture plus artificial tears with artificial tears alone. Two of these studies failed to show significant effects of acupuncture, while one reported significant effects. Two studies reported superior effects of acupuncture plus artificial tears, while one study failed to do so.
Conclusion: These results provide limited evidence for the effectiveness of acupuncture for treating dry eye. However, the total number of studies, the total sample size and the methodological quality were too low to draw firm conclusions.
