    摘要: Disclosed is a method and apparatus for delivering a drug formulation to a human eye. The method includes the steps of inserting the apparatus below the Tenon's capsule and above the sclera at a point posterior to the limbus of the eye and injecting the drug formulation to form a drug depot on an outer surface of the sclera. The apparatus includes a cannula having a distal portion, a proximal portion, and a bend separating the distal portion and the proximal portion. The distal portion has a radius of curvature substantially equal to a radius of curvature of the globe of the eye. A tangent of the distal portion at the bend is disposed at an angle no more than about 56 degrees with respect to the proximal portion.
