Apparatus and methods of treating a hard lens region of an eye with a laser where one method includes identifying a boundary of the hard lens region, selecting a laser-parameter to enable a photodisruptive procedure in the hard lens region and to control a spreading of bubbles in the hard lens region, modifying a mechanical property of a posterior portion of the hard lens region in a proximity of the identified boundary by the photodisruptive procedure, and modifying a mechanical property of a portion anterior to the modified posterior portion of the hard lens region by the photodisruptive procedure. The laser bubbles can be applied to form incisions which are non transverse to an axis of the eye and intersect the lens fibers.


Various arrangements of fluidics systems are disclosed. In one arrangement, an aspiration circuit for a fluidics system is disclosed that selectively controls aspiration. The aspiration circuit comprises an aspiration line operatively connected to a surgical instrument, an aspiration exhaust line operatively connected to a waste receptacle; an aspiration vent line connected at a first end to the aspiration line; and a selectively variable vent valve operatively connected to the aspiration vent line. The variable vent valve may be selectively moved to vary aspiration pressure within the aspiration line. Other fluidics systems are disclosed that include a selectively positionable irrigation valve that may also be incorporated into a fluidics system that includes a variable vent valve.


The present invention is an ophthalmic composition containing a relatively high concentration of olopatadine. The composition is typically an ophthalmic aqueous solution containing relatively high concentrations of olopatadine solubilized within the solution. The composition is preferably capable of providing enhanced relief from symptoms of ocular allergic conjunctivitis, particularly late phase symptoms of ocular allergic conjunctivitis.

A system (100) includes a long cannula (101), an optical fiber (108), and a multi-spot generator (102). The optical fiber (108) can carry a laser beam to a distal end of the long cannula (101). The multi-spot generator (102) is located within a short cannula (103) at the distal end. The short cannula (103) is disposed within the long cannula (101). The multi-spot generator (103) comprises a faceted optical element (104) and a ball lens (106). The faceted optical element (104) can be formed directly onto or separately from the ball lens (106). The ball lens (106) can be spherical or hemispherical. The ball lens (106) is press-fit in the short cannula (103).

The present invention relates to methods for treating an ophthalmic, otic, or nasal infection comprising treating the infected tissue with a suspension composition comprising finafloxacin or a finafloxacin derivative. The present invention also relates to antimicrobial compositions comprising finafloxacin free base or a finafloxacin derivative. The compositions are suitable for the treatment of ophthalmic, otic, or nasal infections.


A cataract surgical system includes a laser source to generate a first set of laser pulses; a guiding optic to guide the first set of laser pulses to a cataract target region in an eye; a laser controller to generate an electronic representation of a target scan pattern, and to control the guiding optic to scan the first set of laser pulses according to a portion of the target scan pattern to create a first photo-disrupted region in the cataract target region; and a Swept-Source Optical Coherence Tomographic (SS-OCT) imaging system to generate an image of a portion of the first photo-disrupted region. The laser controller can generate an electronic representation of a modified scan pattern in relation to the image generated by the SS-OCT imaging system, and control the guiding optic to scan a second set of laser pulses according the modified scan pattern.


Systems and techniques for laser surgery are described. Scan data may be created by determining a coordinate of the object at a set of points along an arc by the imaging system, wherein the coordinate of the object is a Z coordinate of an object layer. An object shape parameter and position parameter may be determined based on the scan data by a system control module by extracting an amplitude and a phase of the scan data determining a center of the object layer based on the extracted amplitude and phase.


A method of irrigating a surgical site and aspirating fluid from the surgical site. The method includes directing a fluid through an aspiration conduit in a phacoemulsification hand piece using a vacuum pressure created from a pump in the hand piece interfacing with the aspiration conduit and directing an irrigation fluid through an irrigation conduit in the hand piece using a pressure created from the pump interfacing with the irrigation conduit. The method also includes increasing an irrigation fluid flow through the irrigation conduit by activating the pump in the hand piece, detecting a pressure associated with a surgical site using a sensor, and controlling intraocular pressure (IOP) by adjusting the pump speed based on the detected pressure.

In various embodiments, a phacoemulsification tip may include a shaft and a cutting edge portion having at least a first and second bend, wherein the at least the first and second bends (102,104) are positioned such that the ultrasonic torsional vibration energy in the tip (100) during ultrasonic torsional vibration is in a twisting vibrational mode along a substantial portion of the shaft (108). The geometry of the tip may be configured to result in a lateral displacement (u), perpendicular to the shaft during torsional vibration of the tip at frequencies between 10 kHz and 60 kHz, of less than approximately 5% to 25% (e.g., 15%) of the lateral displacement at the distal end point of the tip throughout a portion of the shaft extending from the end of a conical portion of the tip through to the first bend in the cutting edge portion of the tip. Software and/or physical modeling may be used to determine the tip geometry.


The present invention generally relates to suspension compositions having a carboxyvinyl polymer such as a carbomer, a galactomannan such as guar, and a borate compound. A sparingly soluble particulate compound such as nepafenac is also included in the compositions. The sparingly soluble particulate compound has a small particle size to enhance bioavailability of the compound.
