Improvement of Soft Contact Lens Wettability After the Instillation of Hyaluronic Acid Eye Drops

Abstract: To evaluate the effect of the topical instillation of hyaluronic acid eye drops with different viscosity on soft contact lens wettability and comfort. Methods: A randomized and participant-masked study was performed, involving 20 participants (25.462.6 years). One eye wore hydrogel (ocufilcon D) contact lenses, and another eye wore silicone-hydrogel (somofilcon A) contact lenses. The in vivo wettability tear film surface quality (TFSQ) index and comfort were measured before and after the instillation of differ… Show more

“…In this regard, a recent in vivo study of our research group using the Medmont E300 reported that the topical instillation of the artificial tears containing HA improved the in vivo wettability of the hydrogel contact lens but had no effect on the silicone-hydrogel contact lens. 12 For the hydrogel contact lens, the topical instillation of 0.1%, 0.2%, and 0.3% HA increased in vivo wettability for 5, 10, and 30 min, respectively.…”

“…It is noteworthy that the effect of HA on in vivo wettability depended on the contact lens material, 12 but this was not observed under in vitro conditions (Table 2). Differences between the hydrogel and silicone-hydrogel contact lenses found that in vivo might be explained by the interaction between the ocular surface physiological conditions, the HA, and the physicochemical properties of contact lens polymers.…”
