Comparative Study of the Efficacy of Either Krytantek Ofteno PF® or Eliptic Ofteno PF® Plus Gaap Ofteno PF® for POAG or Ocular Hypertension.

Phase IV Clinical Study to Compare the Efficacy of the Krytantek Ofteno PF® Plus Gaap Ofteno PF® Combination to the Krytantek Ofteno PF® Plus Gaap Ofteno PF® Combination, in Primary Open Angle Glaucoma or Ocular Hypertension Patients.

Phase IV randomized, double blind, multicenter, parallel group clinical study to evaluate the efficacy of the combined use of Krytantek Ofteno PF® and Gaap Ofteno PF®, both applied every 12 hours, versus the use of Eliptic Ofteno PF® Plus Gaap Ofteno PF®, both applied every 12 hours, in patients with open angle glaucoma or ocular hypertension during 90 days
