      <study_design>Randomization: Randomized, Blinding: Triple blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study, we have two blocks, A and B. Block A is such that the patient's right eye is treated with exosome and the left eye is controlled and B block :The left eye is treated with exosome and the patient's right eye is treated Control is considered. Each time the dice are thrown, if 1, 3 and 5 come, it will be block A, and if 2, 4 and 6 come, it will be block B, and because there is a sixth chance for each person each time, it will be random.

Block A:
Left eye:control  Right eye : Intervention

Block B:
Right eye:control  Left eye : Intervention, Blinding description: In this three-blind study, two vials of eye drops are given to the patient, one with code A and one with code B. And only the supervisor knows which vial contains stem cell exosomes. But the researcher, patient, and clinical data analyzer are unaware of which patient's eye's eye drop contains stem cell exosomes.</study_design>

      <hc_freetext>Dry eye due to Sjogren's syndrome.</hc_freetext>
      <i_freetext>Intervention 1: Intervention group: Wharton jelly mesenchymal stem cell-derived exosomes. Participants will receive artificial tears for 2 weeks to return to normal, then WJMSC-exo 10ug / drop, four times a day for 14 days. The next visit will be 12 weeks later. Intervention 2: Control group: placebo containing phosphate buffered saline. Participants will receive artificial tears for 2 weeks to return to normal and then  10ug / drop of placebo containing phosphate buffered saline in each drop, four times a day for 14 days. The next visit will be 12 weeks later.</i_freetext>
