Abstract: An implantable device for measuring IOP comprises a distal portion, a proximal portion and a conformable elongate support extending between the distal and proximal portions. The distal portion comprises a pressure sensor, for example a capacitor, and the proximal portion comprises a coil. The conformable elongate support extends between the distal portion and the coil so as to couple the distal portion to the coil, and the conformable elongate support is sized to position the sensor in the anterior chamber when the proximal portion is positioned under a conjunctiva of the eye. Positioning of the pressure sensor in the anterior chamber has the benefit of readily accessible surgical access and a direct measurement of the IOP of the eye. The proximal portion comprising the coil can be configured to place the coil between the sclera and the conjunctiva, such that the invasiveness of the surgery can be decreased substantially.

Abstract: Implantable pressure sensors provide for the direct measurement of IOP, for example following cataract surgery. The implantable sensors can couple to the capsule, for example separately from an IOL (intraocular lens), such that the sensor can be used with many commercially available IOLs. The surgeon can identify an IOL appropriate for the patient and place the implantable sensor when the patient has been identified as having glaucoma or at risk for glaucoma. The implantable sensor device can be implanted during IOL surgery.

Abstract: Methods and apparatus for measurement of IOP following glaucoma surgery comprise an implant device having a pressure sensitive capacitor and coil sized for placement along the tissue drainage path, to monitor the success of the surgery and measure IOP directly. The implantable sensor device may comprise a MEMS based capacitive pressure sensor and coil. A complaint material is disposed over the pressure sensitive capacitor and coil to conform with tissue to further decrease invasiveness and such that the implant can measure pressure from at least a first side and a second side when positioned along the drainage path. The implant can work well with trabeculectomies and trabeculotomies, and can be positioned on the sclera at a location corresponding to the bleb, such that the effectiveness of the surgery and medication can be determined postoperatively to detect pressure changes and elevations.
