Study Summary
The purpose of this clinical study is to assess the clinical performance of an investigational toric soft contact lens compared to a commercially available toric contact lens in a crossover dispense trial when worn in a daily wear modality for 30 days, each study lens type.
Primary Outcome
Visual acuity (VA) was collected for each eye individually with study lenses in place using a letter chart. VA was measured in logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with a lower logMAR value indicating better visual acuity. No inferences were pre-specified for the primary effectiveness endpoint; therefore, no hypothesis testing was performed.
Interventions
- DEVICE CLEAR CARE
- DEVICE Lehfilcon A toric contact lenses
- DEVICE Comfilcon A toric contact lenses
