Claim Text:
1. An IOP (intraocular pressure) monitoring device for implantation in an eye of a patient, comprising: a drainage plate; a drainage tube having a first opening and a second opening, the drainage tube being configured to extend into an anterior chamber of the eye and extend to a first sensor outside the anterior chamber, the first sensor in fluid communication with the first opening of the drainage tube, wherein the first opening is located in the anterior chamber and the second opening is formed in the drainage plate so that aqueous humor can flow from the first opening in the anterior chamber to the second opening in the drainage plate; an atmospheric sensing subsystem coupled to the drainage tube, the atmospheric sensing subsystem configured to be exposed to a pressure representative of atmospheric pressure, the atmospheric sensing subsystem comprising: a second an atmospheric pressure sensor; and an atmospheric pressure tube having an opening spaced from the atmospheric pressure sensor and in fluid communication with the atmospheric pressure sensor; a patch, separate from the drainage plate, attachable to a globe of the eye and configured to lie over the opening of the atmospheric pressure tube such that the opening of the atmospheric pressure tube is exposed to the pressure representative of atmospheric pressure under the patch.
