This apparatus treats the lens capsule so as to increase accommodation of the eye. The treatment of the lens capsule may comprise treating a portion of the lens capsule so as to stiffen the treated portion and improve accommodation of the eye. The intermediate portion of the lens capsule may be located between an optically used central portion of the lens capsule and a peripheral portion of the lens capsule connected to zonules of the eye. The stiffened intermediate portion of the lens capsule can improve coupling of the peripheral portion of the lens capsule to the central portion of the lens capsule, such that an amount of accommodation of the optically used central portion of the lens is increased. As the force of the lens capsule to a lens disposed within the lens capsule is increased, the lens may comprise the natural lens of the eye or an artificial lens such as an accommodative IOL. The treatment of the eye to stiffen the intermediate portion may comprise application of one or more of an energy or a substance to the intermediate portion.

Capsular membrane treatments to increase accommodative amplitude

A support is coupled to the lens capsule to increase accommodation. The support may be adjustable, such that patient refraction and accommodation can be adjusted following surgery. The support may comprise rigidity sufficient to decrease radial movement of the intermediate portion of the lens capsule. The support can be placed on the intermediate portion to decrease radial movement of the intermediate portion of the lens capsule and increase radial stretching of an outer portion of the lens capsule extending between the zonules and the intermediate portion coupled to the support, such that the amount of accommodation of the eye is increased. The support may comprise a biocompatible material capable of stable coupling to the lens capsule following implantation, such that the far vision refraction and accommodation of the eye can be stable following surgery.

A phacoemulsification system for operating a surgical handpiece having a handpiece; an irrigation fluid source for supplying irrigation fluid to the eye; an aspiration source coupled to the handpiece in order to aspirate the irrigation fluid from the eye through the handpiece; and a controller for controlling a vacuum in the handpiece, the controller comprising: a sensor for sensing the vacuum in the handpiece; an occlusion parameter, the occlusion parameter being a vacuum level corresponding to an occlusion of the handpiece or a flow rate corresponding to an occlusion of the handpiece; a maximum allowable vacuum level in the handpiece, the maximum allowable vacuum level having at least a first predetermined level; and a trigger value that is set based in part on the occlusion parameter.

Application of vacuum as a method and mechanism for controlling eye chamber stability

The invention is generally directed to systems and methods for fluid control, and more particularly to systems and methods for power and flow rate control for aspiration. In accordance with one embodiment, an aspiration system includes an aspiration line having distal and proximal ends and an aspiration port defined in the distal end; a fluid transport device operatively coupled to the proximal end of the aspiration line; and a flow restrictor operatively coupled to the aspiration line in between the fluid transport device and the aspiration port. To measure occlusion within the line, first and second pressure sensors are utilized, the first sensor being operatively coupled to the aspiration line between the port and the restrictor and the second sensor being operatively coupled to the aspiration line between the restrictor and the fluid transport device. The pressure differential between the two sensors can provide an indication of the onset, presence, and/or elimination of an occlusion.

Systems and methods for power and flow rate control

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

An ophthalmic lens for providing enhanced or extended depth of focus includes an optic having an aperture disposed about an optical axis. The optic includes a first surface having a first shape and an opposing second surface having a second shape, the first and second surfaces providing, a base power and, in some embodiments an add power. The optic further includes an extended focus mask disposed upon at least one of the first shape and the second shape that is configured to provide the enhanced or extended depth of focus for one or more foci of the optic, as compared to a similar optic not having the extended focus mask.

Systems and methods for fluid control during aspiration. In an embodiment, an aspiration system includes an aspiration line having distal and proximal ends and an aspiration port defined in the distal end; a fluid transport device operatively coupled to the proximal end of the aspiration line; and a flow restrictor operatively coupled to the aspiration line in between the fluid transport device and the aspiration port.

The pressure differential between the two sensors can provide an indication of the onset, presence, and/or elimination of an occlusion.

A controller for a phacoemulsification system having a handpiece; an irrigation fluid source configured to supply an irrigation fluid to the eye; an aspiration source configured to aspirate the irrigation fluid from the eye through the handpiece; and a controller comprising a duration timer configured to provide a duration of an occlusion, the controller configured to: sense a value of an occlusion indicating parameter corresponding to an occlusion of the handpiece; measure a time since the occlusion of the handpiece; and control the aspiration source to the handpiece based at least in part on the measured time since the occlusion. The occlusion indicating parameter may be a vacuum level, an irrigation flow rate, and/or an aspiration flow rate.

Application of a system parameter as a method and mechanism for controlling eye chamber stability

A method for operating a surgical system including placing a handpiece in an operative relationship with an eye for a surgical procedure. The method also comprises supplying irrigation fluid from an irrigation fluid source to the eye and applying vacuum from an aspiration source to the handpiece in order to aspirate the irrigation fluid from the eye through the handpiece. The method further comprises sensing a value of an occlusion indicating parameter corresponding to an occlusion of the handpiece and, from the sensing of the value, determining a duration of occlusion. The method additionally comprises controlling a controlled system parameter based at least in part on the duration of occlusion.

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.
