System and method for identifying a component, such as an optical probe or pneumatic scissors, of an ophthalmic surgical device. A component of a surgical device includes an identifier, such as a RFID tag. Data from the RFID tag is transmitted to a RFID reader in the device. A controller determines whether the component corresponding to the received data is operable with the surgical device based on criteria, such as whether the received data is an authorized code that matches data stored in memory or whether the received data solves or satisfies an algorithm. The authorized codes are selected from a larger set of available codes. The controller enables or disables the operation of the device with the component based on whether the criteria is satisfied, the number of uses of the component, an amount of time that has passed since the component has been used, or a geographic location. The RFID data can also be used to calibrate the surgical device for use with the particular component and for inventory and monitoring purposes.

A surgical device for localized delivery of beta radiation in surgical procedures, particularly ophthalmic procedures. Preferred surgical devices include a cannula with a beta radiotherapy emitting material at the distal end of the cannula. The surgical device is particularly suitable for use in the treatment of treat Age Related Macular Degeneration (AMD).

An ophthalmic visualization system can include an imaging device configured to acquire images of a surgical field; a computing device configured to determine an area of interest based on the images; and a display device in communication with the computing device and a surgical microscope, wherein the display device is configured to provide a graphical overlay onto at least a portion of a field of view of the surgical microscope, and wherein the graphical overlay includes a magnified image of the area of interest. A method of visualizing an ophthalmic procedure can include receiving images of a surgical field acquired by an imaging device; identifying an area of interest; generating a graphical overlay including a magnified image of the area of the interest; and outputting the graphical overlay to a display device such that the graphical overlay is positioned over a field of view of a surgical microscope.

A hand-held aspiration device is provided which has a relatively small suction volume along a suction path to improve responsiveness of the aspiration device when the device is activated. The device may be manually powered and may be provided without electronic controls. The device has a suction path which may be purged into a disposal enclosure to reduce the volume of material under the influence of the suction pressure during the procedure. The suction source may also be part of the hand-held unit to further reduce the suction path and suction volume.

The invention relates to a device for performing ophtalmological operations, especially for treating glaucoma. Said device comprises a probe in which a suction channel is arranged. A cutting tool is arranged in the suction channel, by which means separating tissue extending to Schlemm's canal and being sucked into the suction channel can be removed. The device enables openings to be created between the front chamber and Schlemm's canal in a targeted and careful manner.

A system that can be used to perform an ophthalmic procedure. The system may include a patient support that supports a patient and a light source which can direct a beam of light onto the patient's cornea. The system may also include an airflow module that directs a flow of air above the cornea. The flow of air reduces the amount of contaminants that may become attached to the cornea during the procedure.

A method of mitigating an intraoperative hypotony condition using experimental calibrations of different infusion cannulas and vitrectomy probes showing the relationship between infusion pressure, cut rate, and intraocular pressure for various levels of aspiration vacuum in an ophthalmic surgical system.

A control arrangement for an ophthalmic surgical system for phacoemulsifying a lens wherein the system includes an aspiration line for drawing off fluid and shattered lens particles of the eye lens and a phaco handpiece having a needle. The aspiration line runs within the needle and is configured to impart ultrasonic energy to the phaco handpiece for shattering the eye lens via a longitudinal vibration of the needle. The control arrangement includes a transmitter configured to irradiate electromagnetic radiation via the aspiration line and a receiver configured to receive at least a part of the radiation; and, a control unit configured to control an absolute value of a parameter of the ophthalmic surgical system in dependence upon the amount of the received electromagnetic radiation.

An ophthalmic visualization system can include an ocular lens positioned between a macular contact lens coupled to a procedure eye and a surgical microscope. The ocular lens can guide a light beam through the macular contact lens and into the procedure eye, and in combination with the macular contact lens generate an intermediate image of the procedure eye at an image plane between the procedure eye and the surgical microscope. The system can include a reduction lens positioned in the optical path between the surgical microscope and the ocular lens. The reduction lens and/or ocular lens can align a focus plane of the surgical microscope with the image plane. A method of visualizing a procedure eye in an ophthalmic procedure can include positioning an ocular lens and a reduction lens between a macular contact lens and a surgical microscope; and scanning the procedure eye with a light beam.

The present invention relates to safety quality control system and method for excimer laser operation of ophthalmology, and relates to ophthalmology medicine technology. The system includes data input unit for data inputting of diagnosis, examination, operation, post-operating examination, etc.; control system managing server; and display unit. The data input unit and the display unit are contained via LAN or Internet to the control system managing server. The system also includes one spare control system managing server. In the present invention, the system processes all the input data for omnibearing control and management of the operation to ensure the safety and quality of excimer laser operation of ophthalmology.

In various embodiments, a pressure sensor may be configured to detect pressure information associated with pressure in an eye during an ophthalmic surgical procedure. The pressure information may be wirelessly communicated, through a transmitter coupled to the pressure sensor, to a receiver communicatively coupled to a surgical console. The receiver may provide the received pressure information to the surgical console to use in controlling pressure at a surgical site during the surgical procedure. For example, controlling the pressure may include maintaining a desired IOL pressure level within the surgical site at the eye. In some embodiments, the pressure sensor may include a strain gage coupled to a contact lens or a sleeve of an ocular surgical handpiece. Other pressure sensor configurations are also contemplated.

The present invention is related to an image acquisition/output apparatus and a picture system for ophthalmic operation using the same. The picture system for ophthalmic operation according to the present invention includes a near-infrared microscope for irradiating an affect part through an objective lens with near-infrared ray emitted from a light source, and transmitting near-infrared images formed by the objective lens to a first and a second ocular lenses, an image acquisition apparatus for converting near-infrared images transmitted to the first and the second ocular lenses into a first and a second electrical image signals for output, and a display apparatus for receiving the first and the second image signals and outputting them in three-dimensional images.
