13. Patients with poorly controlled glaucoma (defined as intraocular pressure ≥ 25 mmHg despite treatment with antiglaucoma medication) in the study eye.

14. Patients with significant media opacities, including cataract, in the study eye that might interfere with visual acuity, assessment of safety, or fundus photography considered by the principal investigator or investigator.

15. Patients with any diseases in the study eye that could have compromised visual acuity such as amblyopia and anterior ischemic optic neuropathy considered by the principal investigator or investigator.

16. Patients with cataract in the study eye that could have required medical or surgical intervention during the course of the study considered by the principal investigator or investigator.

17. Patients with aphakia with absence of posterior capsule in the study eye.
