Abstract
An ophthalmic implant for drug delivery. The implant includes a primary intracapsular device coupled to a secondary device, wherein, when implanted in a patient's eye, the primary intracapsular device is held in place by the patient's capsular bag and the secondary device is held in place by the primary intracapsular device. The implant may be inserted in the eye by injecting the primary intracapsular device into the eye either before or after attaching the secondary device to the primary intracapsular device, and subsequently positioning the joined secondary device and primary intracapsular device with the primary intracapsular device held in place by the patient's capsular bag and the secondary device held in place by the primary intracapsular device. The secondary device may be designed to hold a tertiary device that can be implanted and attached at the time of surgery or anytime postoperatively.
