- grade 3 or 4 abnormalities
- grade 3 corneal staining in more than two regions
- anterior ocular surgery
- any other ocular surgery or injury within 8 weeks prior to study enrollment
- abnormal lachrymal secretions
- pre-existing ocular irritation that would preclude contact lens fitting
- corneal irregularities
- Polymethyl methacrylate (PMMA) or Rigid Gas Permeable (RGP) lens wear in past 12 weeks
