ABSTRACT:
An intravitreal medicine delivery device and method that includes an implant device through which a wide variety of beneficial medicines including drugs or other pharmacological agents can be introduced into the vitreous cavity over an extended period of time with only a single initial surgery to implant the device. The device and method minimize the surgical incision needed for implantation and avoid future or repeated invasive surgery or procedures. Additional amounts of the initial medicine can readily be introduced or the medication can be varied or changed, as required. Furthermore, the device and method allow the dosage delivered to the vitreous cavity to be controlled, and the device is constructed so as to filter medicines delivered to the cavity and also avoids damage to or interference with other parts of the eye during implantation or during use.
