2Treatment groups
Experimental Treatment
Group I: LID205255 Toric, then Biofinity ToricExperimental Treatment3 Interventions
Lehfilcon A toric contact lenses worn first, with comfilcon A toric contact lenses worn second, as randomized. Each product will be worn bilaterally (in both eyes) during waking hours for at least 5 days per week, with up to 10-12 hours wear time per day over a 30-day period. CLEAR CARE will be used for nightly contact lens cleaning and disinfection.
