The present invention provides implantable ocular drug delivery devices. Generally, the devices have a distal por-tion with a coil shaped body member and a proximal portion which contacts the sclera. In one aspect, the coil-shaped body mem-ber includes a unique configuration including two coiled portions with different pitches, which improves insertion of the device into the eye. In another aspect, the device has a proximal portion that includes a unique cap configuration having a concave distal face that improves stabilization of the device in the eye. In another aspect, the device includes a transitional portion between the cap and the coil-shaped body member that also improves stabilization of the device in the eye. The invention also provides meth-ods for inserting the medical device into the eye, and methods for the treatment of an ocular condition.
