Crosslinked siloxane-urethane polymer contact lens |
摘要 |
A contact lens is described which is synthesized by reaction in a mold of a isocyanate capped poly(dialkylsiloxane) prepolymer with a poly(dialkylsiloxane) di- or polyalkanol. The clear polyurethane rubber contact lens is readily made completely wettable by a transfer-grafting process or post-treatment and has a high oxygen permeability.
