Korean researchers who performed a systematic review have concluded that acupuncture is effective for improving the symptoms of dry eye syndrome (DES). Twenty-one RCTs including data from 1542 eyes met their inclusion criteria. Meta-analysis results demonstrated the superiority of acupuncture in improving symptoms measured by tear-film breakup time (BUT), Schirmer test, corneal fluorescein staining and visual analog symptom scores, compared with artificial tears; BUT and Schirmer test scores were also more improved by acupuncture in combination with artificial tears than by artificial tears alone. Subgroup analyses suggested that acupuncture applied two to three times per week for 21-30 days would be optimal for treating DES.
