Surface Refractive Index Shift of Kalifilcon A Compared With Dailies Total1 and Precision1 Lenses

Completed · Not applicable

Conditions studied: Contact Lens Wear

In brief

This was a single-site, bilateral, repeated-measures insertion study in habitual soft contact lens wearers. Ten participants were enrolled. All participants attended a Screening/Dispensing Visit at which informed consent was obtained and eligibility was assessed. Eligible participants then wore each of three commercially available daily disposable soft contact lens types - kalifilcon A (Bausch + Lomb), Dailies Total1 (delefilcon A, Alcon) and Precision1 (verofilcon A, Alcon), all -3.00 D - bilaterally for wear times of 0.5, 1, 3, 5 and 10 minutes over a total of 6 study visits. A new lens pair was inserted for each wear time, with a 3-5 minute washout period between lens pairs. Immediately following removal, the right-eye lens was measured for surface refractive index on a Metricon M-2010 Prism Coupler.
