Study Summary
The purpose of this clinical study is to evaluate the safety and performance of an investigational soft contact lens compared to a commercially available soft contact lens when worn in a daily wear modality.
Primary Outcome
Visual acuity (VA) was assessed for each eye individually with study lenses in place using a letter chart. VA was collected in Snellen and converted to logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with lower logMAR values indicating better visual acuity.
Interventions
- DEVICE Comfilcon A contact lenses
- DEVICE Lehfilcon A contact lenses
- DEVICE CLEAR CARE
