Problems solved by technology

Patients may undergo regular checkups that may not be ideal for quickly detecting scar tissue formation
Also, spikes in IOP and rapid changes in IOP that cause nerve damage may go undetected, so that, at least in some cases, patients may continue to lose at least some acuity of vision after surgery

Embodiment Construction

[0037] Embodiments described herein will find application in procedures for reducing intraocular pressure, such as draperectomy and trabeculectomy. Although the filtering procedure of dradenectomy is specifically mentioned, there are still new variations to this surgery that may be beneficial according to the embodiments described herein. For example, the methods and devices described herein can be used in a variety of procedures, including creating holes under the conjunctiva, blisters, and channels communicating with the anterior chamber so that aqueous fluid can drain from the anterior chamber, thereby reducing IOP. Also the systems, methods and devices described herein can be used as an aid in many procedures such as retinal surgery and cataract surgery, implants can be positioned at many parts of the eye to directly measure IOP, for example, one of the following or Multiple sites: intracorneal, anterior compartment, anterior, posterior compartment, posterior, vitreous and...

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.
