Abstract
Methods and systems are provided for delivering drug to the eye. The method and system may include implanting into the eye a device which comprises two or more discrete reservoirs, each reservoir containing a drug; and directing focused light to the implanted device to open a first one of the reservoirs and thereby permit the drug to diffuse from the first reservoir to the patient'"'"'s eye.

12. A method of locally administering a drug to an eye of a patient, the method comprising:
-
implanting into the eye a device which comprises two or more discrete reservoirs, each reservoir containing a drug and being defined by one or more substrate materials, at least one of which is impermeable to the drug and impermeable to water and air; and directing focused light to the implanted device, at a first time, to open a first one of the reservoirs and thereby permit the drug to diffuse from the first reservoir to the patient'"'"'s eye. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A system for locally administering a drug to an eye of a patient, comprising:
-
an implantable device which comprises two or more discrete reservoirs, each reservoir containing a drug in solid form and being defined by one or more substrate materials that protect the drug until it is desired to release the drug from the device, wherein the device is adapted to be implantable within the eye and to release drug from each reservoir independently from release of drug from another of the reservoirs following directed contact of the device with laser light. - View Dependent Claims (24, 25, 26, 27, 28)

29. A method of selectively opening an implanted containment reservoir for controlled delivery of a drug to a patient, comprising:
-
implanting in the patient'"'"'s eye a medical device which comprises a substrate in which at least one reservoir is located, the at least one reservoir containing a release system which comprises the drug, the at least one reservoir being defined by one or more substrate materials, at least one of which is impermeable to the drug and impermeable to water and air; and
thendirecting focused light from an ophthalmic laser toward the release system in the at least one reservoir to cause the drug to be released from the device to the patient'"'"'s eye. - View Dependent Claims (30, 31, 32)
