Assessment of an Investigational Frequent Replacement Silicone Hydrogel Lens
- Conditions
- Refractive Ametropia
- Registration Number
- NCT04085328
- Lead Sponsor
- Alcon Research
- Brief Summary
The purpose of this clinical trial is to evaluate the safety and performance of an investigational soft contact lens compared to a commercially available soft contact lens when worn in an extended wear modality.
- Detailed Description
Subjects will be expected to attend 9 office visits. The total expected duration of participation for each subject is approximately 12 months.

Name Time Method Distance Visual Acuity (VA) With Study Lenses - Completed Eyes Day 1 Dispense; Hour 24 Follow-Up; Week 1 Follow-up; Month 1 Follow-up; Month 2 Follow-up; Month 3 Follow-up; Month 6 Follow-up; Month 9 Follow-up, Month 12 Follow-up Visual acuity (VA) was assessed for each eye individually with study lenses in place at a distance of 6 meters 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. No formal hypothesis was formulated for the primary effectiveness endpoint of distance VA; hence, no inferential testing was performed.

Proportion of Ocular Serious and Significant Non-serious Adverse Device Effects (ADEs) Up to Month 12 Calculated as the total number of eyes reporting at least one treatment-emergent, ocular, serious ADE or treatment-emergent, ocular, significant, non-serious ADE, divided by the total number of eyes enrolled and dispensed. An ADE was defined as any adverse event related to the use of the investigational medical device (LID015385) or control product (Biofinity).
