1. A drug delivery ocular implant comprising:
- an elongate outer shell having a proximal end, a distal end, said outer shell being shaped to define an interior lumen;
at least a first drug positioned within said interior lumen;
wherein said outer shell comprises a substantially uniform first thickness;
wherein said outer shell is permeable or semi-permeable to said drug, thereby allowing at least about 5% of total the elution of the drug to occur through the portions of the shell having said first thickness; and

-
making an incision in the temporal portion of the eye, advancing a delivery device associated with a drug delivery implant through the cornea of the eye and across the anterior chamber of the eye, inserting the drug delivery implant into the suprachoroidal space of the eye, wherein the drug delivery implant comprises, an elongate outer shell having a proximal end, a distal end, said outer shell being shaped to define an interior lumen; at least a first drug positioned within said interior lumen; wherein said outer shell comprises a substantially uniform first thickness; wherein said outer shell is permeable or semi-permeable to said drug, thereby allowing at least about 5% of total the elution of the drug to occur through the portions of the shell having said first thickness; and
.wherein said outer shell comprises one or more regions of drug release; positioning said implant such that at least one of said one or more regions of drug release are located proximate an intraocular target; and withdrawing the delivery device from the eye, wherein drug elutes from the implant in sufficient quantity to treat an ocular condition or disorder. - View Dependent Claims (17, 18, 19, 20, 21, 23)
