Purpose: The purpose of this study was to polymerize high wettability contact lenses using pyrrolidone group.
Methods: Amino substituted methacrylate, MMA (Methyl methacrylate), MAA (Methacrylic acid) and HPMA (Hydroxypropyl methacrylate) were polymerized in proportions and pyrrolidone group was added for surface modification.
Results: As a result, the contact angle was measured in the range of 48.72 ~ 65.32°, and the contact angle decreased as the amount of pyrrolidone group was increased.
Conclusions: Pyrrolidone group could be used as a material for improving the wettability of contact lens surface.
