Patients with corneal epitheliopathy or any eye disorder that may predispose the patients to this condition as judged by an ophthalmologist\r\n* Note: Low grades of superficial punctate keratitis, within the range seen in the normal population, should not lead to the exclusion of the patient Subjects with corneal epitheliopathy or any eye disorder that may predispose the subjects to drug-induced corneal epitheliopathy, or may interfere with diagnosis of treatment-emergent corneal epitheliopathy at the discretion of the investigator in consultation with the ophthalmologist/optometrist; low grades of superficial punctate keratitis, within the range seen in the normal population, should not lead to the exclusion of the patient Corneal defects, corneal ulcerations, keratitis, keratoconus, history of corneal transplant, or other known abnormalities of the cornea Active infection or corneal ulcer (e.g., keratitis) History of corneal transplantation Current evidence of corneal disorder/ keratopathy incl. but not limited to bullous/ band keratopathy, corneal abrasion, inflammation/ulceration, keratoconjunctivitis etc., confirmed by ophthalmologic examination.
