摘要:
An ophthalmic drug delivery device and a method for fabricating the same are provided. The ophthalmic drug delivery device includes a shield element and a drug release element. The shield element has a light transmittance more than or equal to 80%. The drug release element is an annular body so that the drug release element surrounds the shield element. The drug release element is neutral and includes a cross-linked neutral collagen, a first hydrophilic biodegradable polymer and a drug. The shield element is acidic and includes a cross-linked acidic collagen and a second hydrophilic biodegradable polymer.
