Outcome Measures
Primary Outcomes (1)
TBUT(Tear break-up time)
The tear break-up time test measures the time in seconds. The time is from the last blinking to the point of tear layer defect or streak-like defect after blinking the eye with 1% of fluorescein. 10 seconds or more as normal, between 5 and 10 seconds as mild dry eye syndrome, and 5 seconds or less as severe dry eye syndrome.
Screening, 6 week, 12 week, 14 week
Secondary Outcomes (7)
OSDI(Ocular Surface Disease Index)
Screening, 6 week, 12 week, 14 week
VAS(Visual analog scale)
0 week, 6 week, 12 week, 14 week
Schirmer's test
0 week, 6 week, 12 week, 14 week
Meibomian gland test
0 week, 6 week, 12 week, 14 week
Fluorescein corneal staining score - Oxford grading
Screening, 6 week, 12 week, 14 week
- +2 more secondary outcomes

Eligibility Criteria
You may qualify if:
- Aged over 19
- Screening both eyes, the corrected visual acuity is 0.2 or more
- Subjects with Fluorescein Corneal Staining score (Oxford grading) ≥ 2 or TBUT test ≤10 at screening
- Subjects with OSDI ≥ 13
- Subjects who voluntarily agreed to participate in this clinical study in written form
You may not qualify if:
- Current or history of ocular disorders possibly affecting the study results (ocular surgery, trauma, diseases) as followings within 2 months:
- Abnormal eyelid function: disorders of the eyelids or eyelashes
- Ocular allergies or currently under the treatment of allergic diseases of the eye (topical ocular mast cell stabilizer, antihistamine use, etc.)
- Cicatricial keratoconjunctivitis caused by herpetic keratopathy, conjunctival scarring (alkali damage, Steven-Johnson syndrome, cicatricial pemphigoid), pterygium, pinguecula, lack of congenital lacrimal, neurogenic keratitis, keratoconus, corneal transplantation
- Those with acute eye inflammation/infection within 1 month
- Those who have undergone eye surgery (including LASIK/LASIK) within 3 months
- Those who had taken lacrimal punctal occlusion, cauterization of the punctum, or intense pulsed light procedure within 3 months
- Those who wear contact lenses within 72 hours of screening or plan to wear contact lens during the study period
- Intraocular pressure (IOP)\> 25 mmHg in more than one side
- Autoimmune disease (e.g., Sjogren's syndrome, Rheumatoid arthritis, systemic lupus erythematosus, Graves' disease)
- Those who have used cyclosporine or diquafosol use in any form (systemic, topical) within 1 month
- Medical condition or history within 1 month to be treated with topical agents besides artificial tears (glaucoma, ocular allergy, ocular inflammation/infectious disease, etc.)
- Those who have taken or are taking steroid drugs or immunosuppressants (Azathioprine, Tacrolimus, Cyclosporin, Mycophenolate mofetil etc.) that may affect immune function within 3 months prior to screening
- Those who had taken antihypertensive drugs such as antihistamine and beta blockers, diuretics, antidepressants (especially tricyclic antidepressants, Parkinson's treatment drugs, etc.) that can worsen dry eye cannot participate in this study
- Severe abnormal liver function tests (Alanine transaminase (ALT) or Aspartate transaminase (AST) values ≥ 2 times the upper limit of normal) and abnormal renal function (Creatinine values ≥ 2 times the upper limit of normal)
