NCT04164459

Brief Summary

In patients with Glaucoma, Xalost S or Xalatan or Taflotan-S are administered for 12 weeks. After 12 weeks, among them, Xalatan administration group are switched to Xalost S or Taflotan-S. Extension study period is 8 weeks. To compare effect (ocular surface damage) and safety of preservative-free Latanoprost/Tafluprost to Benzalkonium chloride-preserved Latanoprost in primary open angle glaucoma or normal tension glaucoma.

Outcome Measures

Primary Outcomes (1)

  • Corneal Staining Score at week 12

    At week 12 of drug administration compare the therapeutic effectiveness between control drug and trial drug evaluated as the effect on corneal staining score. Scale: "Oxford grading system" that divides into 6 groups according to severity from 0 (absent) to 5 (severe). The higher scores mean a worse outcome.

    week 12

Secondary Outcomes (2)

  • Change from baseline in Hyperemia Score at week 4, 8, 12

    baseline and week 4, 8, 12

  • Change from baseline in Intraocular Pressure at week 4, 8, 12
