A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

Provided are systems and methods for correcting a corneal surface irregularity surface in a subject. The system generally comprises a infrared laser, for example, and infrared laser and a laser control unit, a corneal contacting unit, a gel solidifying unit and an electronic device tangibly storing algorithms to operate the units. In the methods, a polymerizable or thermo-reversible gel or polymerized resin is applied to the anterior corneal surface and solidified as a layer over the cornea. A first correcting cut is lasered into the stroma of an applanated cornea, the gel layer is then removed and a second correcting cut is lasered in the stroma of the applanated cornea. The lenticule formed intrastromaly by the first and second correcting cuts is removed such that the cornea has a corrected corneal curvature.

The present invention relates to an ophthalmic treatment apparatus and to a beam control method therefor. The ophthalmic treatment apparatus according to the present invention comprises: a beam generating unit for generating beams having different pulse energies; a bubble sensing unit for sensing whether or not bubbles have been generated, as well as the amount of generated bubbles, on the basis of the pulse energy of the beam generated by the beam generating unit and radiated onto the treatment region of an eyeball; and a control unit for controlling the operation of the beam generating unit such that the pulse energy of the beam generated by the beam generating unit can be adjusted in accordance with the signal from the bubble sensing unit.

Intraocular pressure in an eye is reduced by delivering each of a high resolution optical coherence tomography (OCT) beam and a high resolution laser beam through the cornea, and the anterior chamber into the irido-corneal angle along an angled beam path. The OCT beam provides OCT imaging for diagnostic purposes and surgery planning and monitoring, while the laser beam is configured to modify tissue. A volume of ocular tissue within an outflow pathway in the irido-corneal angle is modified to reduce a pathway resistance present in one or more of the trabecular meshwork, the Schlemm's canal, and the one or more collector channels by applying the laser beam to ocular tissue defining the volume to thereby cause photo-disruptive interaction with the ocular tissue to reduce the pathway resistance or create a new outflow pathway.

A first optical subsystem includes a window with a refractive index n.sub.w and an exit lens having a refractive index n.sub.x. The exit lens is configured to couple to the window to define a first optical axis extending through the window and the exit lens. A second optical subsystem is configured to output a light beam. The light beam is directed to be incident at a convex surface of the exit lens along a second optical axis at an angle that is offset from the first optical axis. The window is configured to detachably couple to the cornea of the eye such that the first optical axis is generally aligned with a direction of view of the eye. The respective refractive indices n.sub.w and n.sub.x are configured to direct the light beam incident at the convex surface of the exit lens through the cornea of the eye toward the irido-corneal angle.

An exemplary surgical device includes a shaft with a lumen defined therethrough and an element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen; wherein motion from the stored position to the deployed position causes a first leg of the element to advance distally relative to the distal end of the shaft, and causes a second leg of the element to move proximally relative to the distal end of the shaft.

Embodiments of this invention generally relate to ophthalmic laser procedures and, more particularly, to systems and methods for lenticular laser incision. In an embodiment, an ophthalmic surgical laser system comprises a laser delivery system for delivering a pulsed laser beam to a target in a subject's eye, an XY-scan device to deflect the pulsed laser beam, a Z-scan device to modify a depth of a focus of the pulsed laser beam, and a controller configured to form a top lenticular incision and a bottom lenticular incision of a lens in the subject's eye.

A laser eye surgery system that has a patient interface between the eye and the laser system relying on suction to hold the interface to the eye, the patient interface using liquid used as a transmission medium for the laser. During a laser procedure sensors monitor the level of liquid within the patient interface and send a signal to control electronics if the level drops below a threshold value. The sensor may be mounted on the inside of the patient interface, within a fluid chamber. Alternatively, a gas flow meter may be added to a suction circuit for the patient interface that detects abnormal suction levels indicating low fluid level.
