Hydrogel lens wettability and deposition in vivo

Background: Wearing a hydrogel contact lens disrupts tear film stability, resulting in a low non‐invasive surface drying time (NISDT) on the lens front surface. Reduced wettability causes deposit formation, reducing the quality of vision and lens comfort. This investigation determined the effect of commercially available HEMA‐based materials on pre‐lens tear film stability and deposition.
