  • Willing and able to wear the study lenses as specified in the protocol;
  • Other protocol-specified inclusion criteria may apply.

Key Exclusion Criteria:

  • Biomicroscopy findings at screening that are moderate (Grade 3) or higher and/or corneal vascularization that is mild (Grade 2) or higher; presence of corneal infiltrates;

T30fA, then Biofinity Toric
Other group
Description:
Lehfilcon A toric contact lenses worn in Period 1, followed by comfilcon A toric contact lenses worn in Period 2, as randomized. The study lenses will be worn bilaterally (in both eyes) during waking hours for at least 12 hours per day during each wear period (30 days [-1/+3] according to randomization assignment). Study lenses will be removed daily for cleaning and disinfection with CLEAR CARE Cleaning & Disinfecting Solution.
