Arms Assigned Interventions
Experimental: OFR
Opti-Free RepleniSH contact lens care solution used for 30 days
Device: Opti-Free RepleniSH
Contact lens care solution containing polyquaternium-1 (PQT)
Device: Contact lenses
Daily wear, frequent replacement contact lenses per participant's habitual brand and power.
Active Comparator: RNM
ReNu MultiPlus contact lens care solution used for 30 days
Device: ReNu MultiPlus
Contact lens care solution containing polyhexamethylene biguanide (PHMB)
Other Name: ReNu MultiPlus
Device: Contact lenses
Daily wear, frequent replacement contact lenses per participant's habitual brand and power.

Detailed Description:

Daily wear soft contact lens wearers reporting significant contact lens-related dryness symptoms were enrolled. Late day dryness with contact lenses, intensity grade 3-5, frequency "sometimes / frequently / constantly" as evaluated by a questionnaire was considered significant.
