Abstract: Improved optical coherence tomography systems and methods to measure thickness of the retina are presented. The systems may be compact, handheld, provide in-home monitoring, allow the patient to measure himself or herself, and be robust enough to be dropped while still measuring the retina reliably.

Abstract: A meniscus shaped lens module comprises one or more structures that decrease an amount of pressure or force to move one or more surfaces of the lens module and increase a separation distance of anterior and posterior surfaces of the module in order to provide an increase in optical power. A lens structure of the module comprises one or more of a pattern of a surface of a central chamber, a meniscus, a reduced diameter or a soft material in order to provide increased amounts of curvature of an outer contact lens surface with decreased amounts of pressure. The pattern can be formed in one or more of many ways, and may comprise one or more of folds, patterning, bellows or concertinaed surface of an optically transmissive material having a substantially uniform thickness such as a sheet of a membrane material.

Abstract: A patient interface system for positioning a patient's eye opposite a laser device for laser surgery is disclosed, including a patient interface for coupling to the patient's eye and a patient interface holder for arranging the patient interface on the laser device. The patient interface holder includes a holder device with an engaging device for reversibly coupling the patient interface to the patient interface holder, and to position the patient interface relative to the patient interface holder with a second positioning device. The engaging device has a spring-loaded engaging body that cooperates with an associated engaging surface of the second positioning device of the patient interface in the coupled state of the patient interface. A method for coupling a patient interface with a patient interface holder of a patient interface system, as well as a patient interface and a patient interface holder for a patient interface system are also disclosed.

Abstract: A patient interface system for positioning a patient's eye relative to a laser device for laser surgery is disclosed that includes a patient interface for coupling to the patient's eye, and a patient interface holder for arranging the patient interface on the laser device. The patient interface holder has a suction duct for connecting to a suction device, and the patient interface has a fluid-conducting device that couples to the patient interface holder, and when in the coupled state, together form a fluid path which fluidically couples the suction duct to the patient interface in order to hold a first positioning device of the patient interface against the patient's eye by a relative negative pressure generated by the suction device. A method is disclosed for coupling a patient interface to a patient interface holder, and a patient interface. A patient interface holder is also disclosed.

Abstract: A method and system provide an ophthalmic lens including a lens body having a chamber therein, a reservoir module coupled with the lens body and an optical fluid. At least part of the lens body is flexible. The reservoir module includes a reservoir and a heat sensitive portion bordering the reservoir. The reservoir has a reservoir volume and is fluidically connected with the chamber. The heat sensitive portion has a shape responsive to a temperature of at least forty five degrees Celsius such that the reservoir volume changes in response to at least part of the heat sensitive portion reaching the temperature. The optical fluid resides in the chamber and the reservoir. A change in the reservoir volume flows a portion of the optical fluid between the reservoir and the chamber such that the flexible portion of the lens body undergoes a shape change corresponding to a base power change.

Abstract: A medical imaging system, is formed of a lighting module, preferably using a single LED. The LED illuminates a reflection chamber, located to receive light from the LED, said reflection chamber terminating in a fiber interfacing surface. An optical fiber, connects to the fiber interfacing surface, and receives light therefrom when said LED is energized. The optical fiber has a first surface connected to the fiber interfacing surface, and has a second surface at an opposite end of the optical fiber from the first surface. A light guide, has a first end, optically coupled to the second end of said optical fiber, and the light guide directs light from the first end into a cone shaped surface at a second end, that directs light away from a center of the cone shaped surface into a hollow cylindrical shape of light, creating an illumination by the light at a distal end of the hollow cylindrical shape opposite the first end.
