TACK FOR INTRAOCULAR DRUG DELIVERY AND METHOD FOR INSERTING AND REMOVING SAME

摘要

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 (12), an anchoring region (14a) and a head (16). The post (12) is for being positioned within the vitreous region of the eye. The post (12) has a first end and a second end, and includes a drug to be administered. The anchoring region (14a) 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 (16) extends radially outwardly from the anchoring region (14a) such that upon insertion of the anchoring region (14a) and post (12) within the eye, the head (16) remains external to the eye and abuts a scleral surface of the eye.
