Abstract: A method to perform high resolution tissue ablation including the steps of forming a beam to deliver optical energy and providing an energy dissipating material is provided. The steps of selecting an area of interest in a target tissue and placing the energy dissipating material adjacent to the area of interest may be included. The steps of directing the beam to the area of interest and scanning the beam across the area of interest to ablate the target tissue may be further included. Also provided is an apparatus and a system for high resolution tissue ablation including a beam to provide optical energy and an injector for placing an energy dissipating material adjacent to an area of interest. Further, the apparatus and system may include at least a mirror and a lens for directing the beam to the area of interest and scanning the beam to ablate target tissue.

Abstract: A punctal plug is disclosed, wherein the punctal plug includes a body portion and a retaining portion. The body portion is defined by an open distal end, an open proximal end and a wall portion. The wall portion further includes at least one window extending therethrough. The retaining flange is configured to have an outer periphery that is larger than the outer periphery of the body portion. A method of delivering a therapeutic agent to a patient using a punctal plug is also disclosed.

Abstract: A glaucoma drainage device has an active valve configured to be located between an anterior chamber of an eye and a drainage location, a power source coupled to the active valve, and a controller coupled to the power source. A first pressure sensor is located in fluid communication with the anterior chamber, a second pressure sensor is located in the drainage location, and a third pressure sensor located remotely from the first and second pressure sensors. The controller reads the first, second, and third pressure sensors once during a period of time and adjusts the active valve to control intraocular pressure.
