  • History of retinal detachment, diabetic retinopathy, or progressive retinal disease.
  • Presence of ocular conditions that may affect the study outcomes.
  • Corneal conditions affecting the corneal structure.
  • History or evidence of any ocular surgical procedure within 1 year prior to Visit 1.
  • Current or recent medical conditions that, in the opinion of the Investigator, would preclude safe participation in the study.
  • Prior, current, or anticipated use of ophthalmic agents other than investigational product during study participation.
  • Participation in any investigational study within 30 days prior to Visit 1 or concomitantly with this study.
