A tack for intraocular drug delivery and a method for insertion and removal of an intraocular device for sustained release of a drug are provided. The tack comprises a post, an anchoring region and a head. The post is for being positioned within the vitreous region of the eye. The post has a first end and a second end, and includes a drug to be administered. The anchoring region is affixed to the second end of the post, and includes a width measured perpendicularly to a longitudinal axis of the tack which varies to provide the anchoring region with a configuration to anchor the tack within at least one of a sclera, a retina and a choroid. The head extends radially outwardly from the anchoring region such that upon insertion of the anchoring region and post within the eye, the head remains external to the eye and abuts a scleral surface of the eye. Other embodiments include a tack comprising a post, a central portion, a head and a suture hole through the head for anchoring the head to the sclera. Alternatively the tack comprises a post having a first portion of liquid drug, a hollow central portion filled with a second portion of liquid drug in fluid communication with the post and a head with an opening which allows for injection of subsequent doses of liquid drug through the head into the central portion.
