Abstract:
1. A biodegradable intraocular implant consisting of: a) a first polylactide polymer having a molecular weight of about 14 kD and an inherent viscosity of about 0.3 dl/g; b) a second polylactide polymer having a molecular weight of about 63.3 kD and an inherent viscosity of about 1.0 dl/g; and c) brimonidine tartrate in an amount of about 20% by weight of the implant; wherein the ratio of first polylactide polymer to second polylactide polymer in the implant is 1:1, 2:1, or 3:1; and wherein the implant is i) a solid, rod-shaped implant formed by an extrusion process and ii) structured to be placed in the vitreous of the eye.
