- Brief Summary
The purpose of this study is to assess whether acupuncture is more effective than artificial tear drop in the treatment of dry eye.
- Detailed Description
Dry eye is one of the common diseases in ophthalmology. It affects not only patients' daily activities such as reading, carrying out professional work, using the computer, watching television, and driving, but also bodily health conditions such as bodily pain, discomfort and lower energy and vitality.
Currently, artificial tears are easily subscribed or used in the shape of OTC drugs. However, preservatives in artificial tears may exacerbate ocular surface inflammation and the safety of anti-inflammatory treatment is not well established.
Acupuncture, one of the most popular CAM interventions, showed some favourable effects over artificial tears for dry eye in several randomised controlled trials (RCTs). The evidence obtained from these trials is quite limited because all of these RCTs were conducted under high risk of biases. Therefore, well-designed RCTs are needed to establish the efficacy of acupuncture for dry eye.
In a clinical trial, cost-effectiveness and qualitative researches can be carried out parallely. Through this kind of mixed method approaches, various compartments, consisting acupuncture treatment effects are able to be revealed totally.
In this context, the investigators designed a multi-center randomized controlled trial, comparing acupuncture treatment and artificial tear drop with immunoassay for the change of tear cytokine concentration, cost effectiveness study and qualitative research in a mixed method approach.

- Primary Outcome Measures
Name Time Method Ocular Surface Disease Index (OSDI) Up to 13 weeks This questionnaire is a 12-item instrument for ocular irritation and impact on visual function in dry eye sufferers. It can provide quantifiable results of dry eye symptom frequency and vision-related functioning. Korean version of the OSDI questionnaire will be used. Follow up measurement will be assessed after 4, 5, 9 and 13 weeks from the first visit.
- Secondary Outcome Measures
Name Time Method Visual analogue scale (VAS) for self-assessment of ocular discomfort Up to 13 weeks Self-reports on ocular symptoms concomitant with dry eye, such conditions as ocular itching, foreign body sensation, burning, pain and dryness as well as for blurred vision, sensation of photophobia, ocular redness and sensation of tearing. Follow up measurement will be assessed after 4, 5, 9 and 13 weeks from the first visit.
Schirmer I test with anaesthesia Up to 13 weeks This ia a method for checking basic tear secretion. Schirmer test paper (Color Bar™ Eagle Vision, USA) will be inserted on the lateral third of the lower eyelid with the participant's eye closed for five minutes. Follow up measurement will be assessed after 5 weeks and 13 weeks from the first visit.
Tear Film Break Up Time (BUT) Up to 13 weeks This is a method for observing tear film stability. Sodium fluorescein (2.5%) will be instilled in both eyes and the tear break-up time (the interval between the last complete blink and the first appearance of a dry spot or disruption in the tear film) will be measured. Follow up measurement will be assessed after 5 weeks and 13 weeks from the first visit.
General Assessment by acupuncture practitioner and participants Up to 5 weeks Practitioners and participants will evaluate the improvement of ocular symptoms after treatment. They can chose one of the following 5 grades: Excellent, Good, Fair, Poor and Aggravation.
Self reports about experiences of using other dry eye-related treatments after the end of each intervention. Up to 13 weeks For cost-effective analysis, all experience of using other dry eye-related treatments after the end of each intervention should be reported by participants. It contains frequency of hospital visit and treatments methods. Follow up measurement will be assessed after 9, 13 weeks from the first visit.
Quality of life (QOL) Up to 13 weeks One questionaire for QOL, related to dry eye, is asked. Follow up measurement will be assessed after 4, 5, 9 and 13 weeks from the first visit.
Case reports on adverse events for the evaluation of safety Up to 13 weeks Adverse events, adverse acupuncture or artificial tear drop reaction, serious and unexpected adverse acupuncture or artificial tear drop reaction and serious adverse event will be reported by participants and checked by practioners in every visit. Number of participants with adverse events will also be recorded.
Qualitative analysis (additional study) Up to 13 weeks Questionaires with open-ended question about personal experiences for dry eye, acupuncture treatment and usage of artificial tear drop will be distributed to every participant of both group. Follow up measurement will be assessed after 4 and 13 weeks from the first visit.
Cost-effectiveness analysis between acupuncture and artificial tear drop treatment (additional study) Up to 13 weeks Cost-effectiveness of acupucnture will be analyzed using Ocular Surface Disease Index (OSDI) variable, comparing the cost of artificial tear drops. the Cost which all participants will use for dry eye during the trial period, will be recorded in every visit.
