Abstract

A flexible ocular insert device adapted for the controlled sustained release of an ophthalmic drug into the eye. In one embodiment, the device includes an elongated body of a polymeric material in the form of a rod or tube containing a pharmaceutically active ingredient and with at least two anchoring protrusions extending radially outwardly from the body. The device has a length of at least 8 mm and the diameter of its body portion including the protrusions does not exceed 1.9 mm. As shown in Figure 7, the device (70) with ribbed configuration has circular cylindrical walls (72) with domed end portions (74). A series of arcuate shaped ribs (76), of circular, toroidal cross section, are provided at intervals along the length of the device (70).
