The invention provides implants suitable for use as an artificial cornea, and methods for making and using such implants. Artificial corneas having features of the invention may be two-phase artificial corneas, or may be three phase artificial corneas. These artificial corneas have a flexible, optically clear central core and a hydrophilic, porous skirt, both of which are biocompatible and allow for tissue integration. A three-phase artificial cornea will further have an interface region between the core and skirt. The artificial corneas have a high degree of ocular tolerance, and allow for tissue integration into the skirt and for epithelial cell growth over the surface of the prosthesis. The use of biocompatible material avoids the risk of disease transmission inherent with corneal transplants, and acts to minimize post-operative inflammation and so to reduce the chance or severity of tissue necrosis following implantation of the synthetic cornea onto a host eye.

An exemplary method and system monitors patient safety to, for example, minimize disease transmission from healthcare providers with unclean hands to patients and their surroundings. Signals (for example, infrared and radio frequency) among an area monitor, identification badge, and cleaning agent dispenser help locate and identify objects (persons and equipment). Objects may be identified and monitored using object recognition and motion tracking, zones (around the objects) are defined based on proximity to the object, and subzones are defined within zones to enhance monitoring of compliance with hygiene guidelines. The movements of objects may be monitored using motion tracking, and the objects may be identified by detecting a signal pulse in the object's silhouette. A caretaker entering a zone, moving between subzones, or contacting objects without dispensing cleaning agent from a dispenser can be alerted that they have unclean hands. Observations can be automatically recorded for real-time alerting and auditing purposes.
