likely to interfere with visual acuity
2. Moderate or severe dry eye as defined by corneal fluorescein staining score of =3 on
Oxford scale at Screening
3. Any clinically significant pupillary or iris abnormality (e.g., anisocoria of >1 mm
between eyes at Screening or baseline, abnormal pupil shape in either eye, iris
transillumination defects, or any congenital or traumatic defect of the iris)
4. Narrow iridocorneal angles (Shaffer grade =2 or lower on gonioscopy examination),
history of angle-closure glaucoma, or previous iridotomy
5. Intraocular pressure (IOP) <8 mmHg or >23 mmHg in either eye or history of glaucoma or
ocular hypertension
6. Any clinically significant abnormal lens finding (e.g., cataract, loose zonules,
exfoliation, pseudoexfoliation)
7. History of any intraocular surgery including cataract surgery or phakic intraocular
lens surgery
8. History in either eye of previous corneal inlay, full- or partial-thickness corneal
transplant, radial keratotomy or any corneal surgery including laser-based corneal
refractive surgery

eye or known history of retinal detachment, retinal trauma, retinal or vitreal
surgery, or clinically significant retinal disease in either eye
10. Clinically significant strabismus or diplopia
11. History of stereo vision difficulties
12. History of optic neuropathy or amblyopia in either eye
