A computer-based surgery support system and method for obtaining information of surgical procedures from networked equipment in an operating room, storing the retrieved information in a database, receiving a request for the stored information from a user terminal, and providing the stored information in accordance with the received request. The networked equipment may be configured for use in cataract surgical procedures, such as a phacoemulsification system.

Computer-based operating room support system

A phacoemulsification system and method, and a surgical foot pedal device, system and method. The present invention may include a console comprising a plurality of modes for at least one physically associated surgical instrument, and a foot pedal communicatively associated with said console and suitable for varying ones of the plurality of modes. The foot pedal may include a housing comprising the communicative association, and comprising at least one potentiometer and at least two top switches for the varying of the ones of the plurality of modes, a treadle rotatably mounted within the housing and suitable for depressing the at least one potentiometer, and at least two side switches movably associated with the treadle for the varying of the ones of the plurality of modes.

Foot pedal system and apparatus

A method and apparatus for delivering energy during a surgical procedure such as phacoemulsification is provided. The method and apparatus include applying energy during at least one pulsed energy on period, typically sufficient or intended to rapidly induce and beneficially employ transient cavitation. Applying energy during the pulsed energy on period comprises applying energy during a first high energy period, and applying energy during a second nonzero lower energy period.

Modulated pulsed ultrasonic power delivery system and method

A method and apparatus for delivering energy during a surgical procedure such as phacoemulsification is provided. The method and apparatus include applying energy during at least one pulsed energy on period, comprising applying energy during a series of short burst periods, the short burst periods interspersed by short rest periods. The method and apparatus further comprise delivering minimal energy during a long off period, the long off period comprising a relatively long period when minimal energy is applied, wherein one long off period follows each pulsed energy on period. The short burst periods and the short rest periods are relatively brief in duration as compared with the long off period.

System and method for pulsed ultrasonic power delivery employing cavitation effects

Phacoemulsification apparatus includes a phacoemulsification handpiece having a needle and an electrical circuitry for ultrasonic vibrating the needle. A power source provides pulsed electrical power to the handpiece electrical circuitry and an input is provided for enabling a surgeon to select an amplitude of dislighted pulses and a pulse width. A control system and pulse duty cycle is provided for controlling the off duty cycle to insure heat dissipation before a subsequent pulse is activated, including a foot pedal switch.

Control of pulse duty cycle based upon footswitch displacement

A method and apparatus for performing modulated fluid delivery and aspiration during a surgical procedure such as phacoemulsification is provided. The method and apparatus include delivering fluid and/or aspirating fluid in a modulated or pulsed manner during a surgical procedure, including applying fluid and/or aspirating fluid in connection with ultrasonic energy at a level and for a time period sufficient to induce transient cavitation. Fluid may be applied and/or aspirated at a timing sequence and duty cycle similar to or different from application of ultrasonic energy delivery.

System and method for modulated surgical procedure irrigation and aspiration

An accommodating intraocular lens (aIOL) is disclosed, with an optic that changes shape in response to an ocular force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. A surface adherent improves the accommodative performance of the haptic, such that compressive/tensile forces may be more efficiently transferred from the haptic to optic. One way to enhance force transfer is to provide a surface layer of an adhesive to the haptic and/or optic, for instance a reversible bioadhesive material. Or, portions of the exterior surface of the IOL may have microfibers thereon that mimic the adhesive properties of Gecko feet. Another aspect is application of a reversible bioadhesive material to the interior of the empty capsular bag prior to introduction of an injectable polymer IOL.

Fixation of ophthalmic implants

A method and apparatus for delivering energy during a surgical procedure such as phacoemulsification is provided. The method and apparatus include delivering energy during a surgical procedure, including applying energy at a level and for a time period sufficient to induce transient cavitation, and reducing applied energy after applying energy during a second nonzero lower energy period.

System and method for pulsed ultrasonic power delivery employing cavitational effects

Phacoemulsification apparatus includes a phacoemulsification handpiece having a needle and an electrical system for ultrasonically vibrating said needle along with a power source for providing pulsed electrical power to the handpiece electrical system. Irrigation fluid is provided to the handpiece needle and aspirating fluid is removed from the handpiece needle. A determination of a voltage current phase relationship of the provided electrical power is made and in response thereto a control system varies a power level duty cycle provided to the handpiece electrical system from the power source and/or modify the aspiration flow rate. In addition, a separate input enables manual control of pulse amplitude. The control system provides a pulsed electrical power of less than 20 millisecond pulse duration.

Micro-burst ultrasonic power delivery

Control apparatus for an ultrasonic phacoemulsification handpiece utilizes flow rates and temperature measurements as well as power provided to a handpiece for calculating a matrix of power level duty cycle combination that would not generate sufficient heat to create a burn in eye tissue and either prevent operation of handpiece in the matrix or alert a surgeon of such use.
