Abstract

|
Purpose : Recently research and development became not only conventional soft contact lens material lens but also functional contact lens. In this study, we manufactured functional contact lens with antimicrobial.
Methods : We mixed AgNO3 with conventional soft contact lens material. And then we copolymerized at 70℃ for about 40 minutes, at 80℃ for about 40 minutes and finally at 100℃ for about 40 minutes by the progress of heat treatment.
Results : In case of physical properties, the results showed 1.502~1.504(refractive index of dry) and 1436~1.445(wet of refractive index), 34.54%~39.03%(water content) and 79.1%~83.8%(visible transmittance).
Conclusions : We copolymerized AgNO3 with conventional soft contact lens material. We judged that we made the copolymer physical properties which is suitable for conventional contact lens.
