Clinical Performance and Wearer Experience with Two Contemporary Daily Disposable Silicone Hydrogel Lenses
By Walsh K, Moezzi AM, Guthrie S and 2 others.
Abstract
Objective
To compare the clinical performance and wearer experience of two contemporary spherical daily disposable silicone hydrogel lenses, somofilcon A and verofilcon A.
Methods
In this prospective, double-masked, bilateral, randomized, crossover study, habitual contact lens wearers were recruited at a single site. Participants wore somofilcon A or verofilcon A lenses bilaterally on a daily disposable basis for one week, then crossed over to the alternate lens. The primary endpoint was participant-reported handling (insertion and removal) at the 1-week follow-up. Secondary outcomes included lens fit, surface wettability and deposits, non-invasive tear break-up time (NITBUT), visual acuity, subjective comfort, satisfaction, preference, diary ratings, and slit-lamp ocular health.
