Methods are provided for medical treatment or diagnosis of a patient. The method includes implanting into the patient a device which comprises (i) a substrate in which at least one reservoir is located and covered by a first reservoir cap, (ii) a drug or sensor located in the reservoir, and (iii) control circuitry and a power source for disintegrating or permeabilizing the reservoir cap, and (iv) an external interface to receive incident light energy; and directing focused light to the external interface of the implanted device to actuate disintegration or permeabilization of the reservoir cap to release the drug or expose the sensor. The device may implanted onto or into the sclera or other tissue surface of the eye of the patient. The focused light may be laser light, which may be used to transmit power or data to the device.

We claim: 1. A method for medical treatment or diagnosis of a patient, the method comprising: implanting into the patient a device which comprises (i) a substrate in which at least one reservoir is located and covered by a reservoir cap, (ii) a drug or sensor located in the reservoir, and (iii) control circuitry and a power source for disintegrating or permeabilizing the reservoir cap, and (iv) an external interface to receive incident light energy, the external interface being operatively coupled to the control circuitry or the power source; and directing focused light to the external interface of the implanted device to actuate, via the control circuitry and power source, disintegration or permeabilization of the reservoir cap to release the drug or expose the sensor. 2. The method of claim 1, wherein the device is implanted onto or into the sclera or other tissue surface of the eye of the patient. 3. The method of claim 1, wherein the focused light is laser light. 4. The method of claim 3, wherein the laser light transmits power to the device. 5. The method of claim 3, wherein the laser light transmits data to the device. 6. The method of claim 1, wherein the external interface comprises a photocell, photodiode, phototransistor, or a combination thereof. 7. The method of claim 1, wherein the focused light is directed through the cornea of the eye to the external interface. 8. The method of claim 1, wherein the drug comprises an angiogenesis inhibitor. 9. The method of claim 1, wherein the drug comprises a steroid. 10. The method of claim 1, wherein the sensor comprises a chemical sensor. 11. The method of claim 1, wherein the sensor comprises a pressure sensor.
