Abstract:
The present invention pertains to a system (or engine) that monitors a system's performance during a surgery, analyzes that performance, and makes recommendations to the user/surgeon for changes in his settings and/or programs that will result in more effective and time-efficient surgeries. Further, the system may comprise one or more components, including, but not limited to, a user preference filter, a surgical circumstances filter, a surgical instrument, a real time data collection module, and an analysis module.

Abstract:
A device for inserting an intraocular lens (IOL) into an eye includes a tubular body member with an inner surface and a plunger with an gripping device that is receivable within the body member. The gripping device includes a locking member and is configured such that when urged longitudinally in a distal direction, the gripping device is movable in the distal direction within the body member. However, when urged longitudinally in a proximal direction, the gripping device is prevented from moving in the proximal direction by the locking member engaging with the inner surface of the body member. As such, inadvertent movement of the plunger in the proximal direction caused by pulling back on the plunger is substantially prevented. If proximal movement of the plunger is desired, then the plunger may include handle that is operatively coupled to the gripping device such rotation of the handle causes the handle to move longitudinally in the body member. Accordingly, the plunger may be advanced or moved distally by longitudinally pushing the handle and/or by rotating the handle.
Abstract:
Intraocular lenses for providing accommodation include an anterior optic, a posterior optic, and a lens structure. In one such lens, the lens structure comprises an anterior element coupled to the anterior optic and a posterior element coupled to the posterior optic. The anterior and posterior elements are coupled to one another at a peripheral region of the intraocular lens. The intraocular lens may also includes a projection extending anteriorly from the posterior element that limits posterior motion of the anterior optic so as to maintain a minimum separation between anterior optic and an anterior surface of the posterior optic.
Abstract:
A method for operating a surgical system including a control unit having a vacuum sensor and/or a flow rate sensor, the method including placing a handpiece in an operative relationship with an eye for a surgical procedure and thereafter supplying irrigation fluid to the handpiece while applying a vacuum to the handpiece to aspirate the irrigation fluid from the eye through the handpiece. During fluid aspiration, a vacuum level and/or flow rate is sensed which corresponds to an occlusion of the handpiece and from the sensed vacuum level and/or flow rate, a duration of the occlusion is determined. In response to the determined duration of occlusion, at least one of the handpiece parameters is varied.
Abstract:
A system for providing vision contains an aberrometer, a wavefront sensor, and a transfer optical system. The aberrometer is configured to measure a received wavefront. The aberrometer includes a wavefront sensor and a transfer optical system for transferring an input wavefront so as to the provide the received wavefront at or near the wavefront sensor. The system also includes a processor in communication with the aberrometer, a readable memory, and instructions located within the memory. The readable memory contains one or more system error parameters and instructions available to the processor. The instructions are for determining at least one aberration of the received wavefront and calculating the input wavefront based on the received wavefront and the one or more system error parameters.
Abstract:
An ophthalmic lens for providing a plurality of foci includes an optic having an anterior surface, a posterior surface, and an optical axis. The ophthalmic lens has a first region and a second region. The first region has a first refractive optical power and includes a first base curvature having a finite first radius of curvature and a first phase plate having at least one diffraction order with a diffractive optical power. The first region is configured for forming a first focus and a second focus. The second region has a second refractive optical power and includes a second base curvature having a finite second radius of curvature that is different from the first radius of curvature and a second phase plate having at least one diffraction order with a diffractive optical power. The second region is configured for forming a third focus that is between the first focus and the second focus. The ophthalmic lens may be configured so the first focus provides distant vision, the second focus provides near vision, and the third focus provides intermediate vision.
Abstract:
A method and apparatus for managing the establishment of a wireless connection between an instrument host and a non-fixed device is provided. The method comprises acquiring the non-fixed medical device address over a fixed wire by replacing the traditional wireless searching mechanism. The method also comprises providing an authentication mechanism between the instrument host and the non-fixed device, for example, across a wireless communications network.
Abstract:
An intraocular lens with a hydrophilic polymer coating composition and methods for using same are provided. Specifically, a composition suitable for reducing tackiness in intraocular lens is provided wherein an acrylic intraocular lens is treated by vapor deposition with an alkoxy silyl terminated polyethylene glycol polymer composition. Methods for making an intraocular lens with a hydrophilic polymer coating are also provided.
Abstract:
A lens and cartridge packaging system and method of use which simplify the removal and transfer of an IOL to an IOL insertion device is disclosed. The packaging system enables a user to easily load an IOL into a cartridge without the use of forceps. In addition, the packaging system also allows a user to fold and insert the IOL into a cartridge without damaging the IOL and/or compromising IOL sterility. In addition, the related methods of use minimize and/or eliminate damage to the IOL during unpackaging, folding, transfer and loading procedures.
