Study Summary
The primary objective of this study is to evaluate the overall clinical performance of an investigational silicone hydrogel contact lens over 2 weeks of daily wear.
Primary Outcome
Front surface wettability (i.e., assessment of the disruption of the front surface wettability of the contact lens) was assessed by the investigator for each eye individually. Front surface wettability was collected on a 5-point scale, where where Grade 0 = a smooth uniformly reflecting surface and Grade 4 = non-wettable lens surface. No formal hypothesis was predefined for the primary endpoint. No inferential testing was performed.
Interventions
- DEVICE Lehfilcon A contact lenses
- DEVICE Multipurpose disinfection solution
