• Participant with clinically significant corneal disease

• Any evidence of severe or uncontrolled systemic diseases including active bleeding diatheses, active infection, psychiatric illness/social situations, geographical factors, substance abuse, or other factors which in the investigator's opinion makes it undesirable for the participant to participate in the study or which would jeopardize compliance with the protocol
