Evaluating the initial and end‐of‐day wettability of contemporary daily disposable contact lenses using various <i>in vitro</i> methods
The sessile drop technique produced the most measurable differences in wettability between different lens types, whereas the captive bubble technique was not able to provide any measurable differences between lenses. NIKBUT measurements may provide a better measure of on-eye wettability, but variability in the results using the current eye model still needs to be addressed in future studies for improved repeatability. Although the contact lenses showed different contact angles and NIKBUT results, their in vitro wettability did not significantly change over the 16 hours of simulated wear in terms of the captive bubble or NIKBUT values.
