<p>The purpose of the present invention is to provide a medical device for the controlled release of a drug suitable for an ophthalmic lens that, compared to a conventional contact lens for controlled release of a drug, releases a reduced initial controlled longer-release amount of the drug retained in the device and as a result, thus enabling longer-term controlled release of the drug in a therapeutically effective dose, such device having the same oxygen permeability as that of conventional SHGCL. The foregoing is accomplished by a medical device for the controlled release of a drug comprising an amphiphilic hydrogel that retains a drug, where the rate of controlled release of the drug is 50 wt% or less 24 hours after drug release is initiated.</p> |
