Clinical Trial Summary

The purpose of this study is to investigate the safety and effectiveness for applying the electrical stimulation transcutaneously around the eyes and peripheral nerves nearby. The outcomes are compared between the patients with mild- or moderate-level dry eye disease using the real electrical stimulator and the sham electrical stimulator.

Description:

Duration of study period(per participant): Screening period (0-4weeks), Intervention period (5weeks). Patient needs to visit site at least 3 times (Screening, V4, V6), V2 can be done with screening visit. The clinical trial device performs a personal electrical stimulator around the eyes and peripheral nerves for 28 days (7 times/week, 30 minutes each time). During the study period, dry eye examination and treatment methods (only eye drops provided in clinical trials are applied) are carried out in the same way.

• Patients with an abnormality of the eyelid structure
• Patients with moderate to severe meibomian gland disorders
• Those with underlying diseases such as glaucoma, burns, Steven Johnson Syndrome, vitamin A deficiency-related diseases, thyroid dysfunction-related diseases, and neurotropic keratinis.
• Other clinically significant ophthalmic diseases that are not caused by dry eye disease After corneal transplant surgery, corneal surface disease, abnormal corneal sensitivity, abnormal tear excess, etc. may confuse the interpretation of clinical trial results.
• Patients with uncontrolled systemic chronic diseases such as diabetes) or a history of malignant tumors
• Autoimmune disease patients
• People taking medications such as Steroids, immunosuppressants, omega 3 and anticholinergic drugs, etc.
• Pregnant or lactating women

• Medically permitted contraceptive methods: condoms, oral contraceptives that last at least three months, injections or insertion contraceptives, and installation of intrauterine contraceptives, etc.
• Patients with a history of drug or alcohol abuse
• People who are allergic to medicines such as Fluorescein Solution or eye drop anesthetics
• A person who is judged to have a problem in electrode attachment due to an inflammatory reaction or other dermatological problems in the periorbital skin where the electrode of the medical device for clinical trial is attached
• A person who is judged to have other reasons for prohibiting the use of medical devices for clinical trials
• Any other cases that PI considers hard to participate in this clinical trial(e.g. heart-related problems, seizure, epilepsy. Patients transplanted metal or electronic device in head & neck. Patient suffering from unknown pain. Patients who are warned not to use out clinical trial device or is prohibited from using it.)
