The drug sustained-release medical equipment

Object of the present invention to provide a drug sustained-release ophthalmic lens suitable for medical instruments used in the medical drug release as compared with a conventional contact lens for sustained drug release device with reduced drug held the amount of initial release, it is possible to release a therapeutically effective amount of a long period of time the drug, and having conventional SHGCL oxygen permeability of the same level. The above object is achieved by the following instruments used medical drug release, the drug sustained-release medical instrument comprising an amphiphilic hydrogel for holding a drug, wherein the drug release rate of the drug release from the 24 hours after the start of 50 wt% or less.
