Abstract Eye drops are the usual method to treat eye diseases, and gel polymer provides the carrier which could be used for ophthalmic drug delivery. However, the stable and sustained release is the main issue for the ophthalmic drug and is concerned by many researchers. In this study, composite hydrogels were prepared using 2-hydroxyethyl methacrylate (HEMA), and N-vinyl-2-pyrrolidone (NVP) used for ophthalmic drug loading and release. According to the results of Fourier transform infrared spectroscopy (FTIR), the disappearance of the C=C bond in hydrogel indicated that the copolymerization reaction between HEMA and NVP was successful.
