  • Be able and willing to follow all instructions and attend all study visits;
  • Be 45-75 years of age of either sex and any race or ethnicity at Visit 1;
  • Have +1.00 to -4.00 diopter (D) of sphere calculated in minus cylinder (so that spherical equivalent (SE) results in myopia no more severe than -4.00 D MRSE) in both eyes determined by manifest refraction documented at Visit 1;
  • Have ≤2.00 D of cylinder (minus cylinder) in both eyes determined by manifest refraction documented at Visit 1;
  • Be presbyopic as determined at Visit 1

Exclusion Criteria

Subjects must not:

  • Be a female of childbearing potential who is currently pregnant, nursing, or planning a pregnancy;
  • Have known contraindications or sensitivity to the use of any of the study medications or their components;

  • Have moderate or severe dry eye defined as total central corneal fluorescein staining in either eye at Visit 1;
