An ophthalmic stimulator for constricting a pupil of an eye comprises an irradiation control system, to generate an irradiation control signal; an irradiation source, coupled to the irradiation control system, to generate an irradiation; and an irradiation delivery system, coupled to the irradiation control system, to receive the irradiation from the irradiation source, and to deliver a patterned irradiation to an iris of the eye; wherein the irradiation control system controls at least one of the irradiation source and the irradiation delivery system with the irradiation control signal so that the patterned irradiation causes a long-term constriction of the pupil of the eye.

Systems and methods of laser treatment of the intact crystalline lens to increase ionic transport of antioxidants in specific areas where flexural changes and transparency reduction come from lens aging. Microchannels created in patterns and grids placed strategically in the inner lens carry antioxidants from the sourcethe anterior and the epitheliuminto areas scarce or void of transport mechanisms (and thus scarce of antioxidants). A variety of patterns are utilized to facilitate ions traveling along new pathways.

The present invention relates to a laser surgery apparatus for contact laser surgery and to a method of using the laser surgery apparatus. The laser surgery apparatus (1) comprises a contact laser scalpel (3) for contact laser surgery, the contact laser scalpel (4) comprising an optical fiber (4) of IR laser radiation transmissive material and terminating at an optical fiber tip (5) having an exposed core region, and support means for holding said fiber and for positioning said scalpel (3). Said fiber tip (5) is tapered and disposed at a distal end of the scalpel (3) for contacting a tissue to be cut and comprises an uncoated contact surface (6) for transmit ting laser radiation and a guiding surface that is at least partially reflective to laser radiation and provided such that laser radiation guided by said optical fiber (4) to said fiber tip (5) will be at least partially reflected by said guiding surface and emitted through said uncoated contact surface. The contact laser surgery apparatus further comprises a pulsed laser source (2) adapted to provide pulse durations in the femtosecond, picosecond and/or nanosecond range, and light transmitting means (9) connecting said laser source (2) to said optical fiber (4) of said scalpel (3) for conveying laser radiation from said laser source (2) to said optical fiber (4) such that the conveyed laser light is emitted at said uncoated contact surface of the fiber tip.

Glaucoma can be treated by implanting an intraocular shunt into an eye. The eye has an anterior chamber and sclera. A shunt can be placed into the eye to establish fluid communication from the anterior chamber of the eye through the sclera.

A planning device for generating control data, a treatment apparatus for refraction correction eye surgery and a method for generating control data for such a treatment apparatus which allows an improved subsequent refraction correction. The planning device includes a calculation processor for defining a cut surface of the cornea for post-treatment, wherein the calculation device is designed such that a change of thickness of the epithelium is taken into account in the calculation, which was caused essentially by a pretreatment.

Laser-based ophthalmic systems and methods can be used to treat glaucoma and other conditions of the eye. The laser system can be used to form openings or partial-thickness channels in the trabecular meshwork to promote aqueous humor outflow. Scanning approaches provided herein can create either fully perforating full hole ablations or partial-disruption soft holes.
