Additive manufacturing techniques are used to form an artificial intra-ocular lens (IOL) directly inside the human eye. Small openings are formed in the cornea and lens capsule of the eye, and the crystalline lens is broken up and removed through the openings; then, a material is injected into the lens capsule through the openings, and the focal spot of a pulse laser beam is scanned in a defined pattern in the lens capsule, to transform the material in the vicinity of the lase focal spot to form the IOL in a layer-by-layer manner. In one embodiment, stereolithography techniques are used where a pulse UV laser source is used to photosolidify a photopolymer resin. The liquefied resin is injected into the eye through the openings, after which only part of the resin, having the shape of the desired IOL, is selectively cured with the UV laser beam, via progressive layer formation.

A method for creating cuts in a transparent material using optical radiation, the optical radiation being focused onto the material in a focal point and the focal point being shifted along a curve: A simple or double harmonic curve is used when seen at a right angle to a main direction of incidence of the radiation and preferably successively traveled curves do not lie on top of each other.

In certain embodiments, a device comprises a laser device and a control computer. The laser device directs a laser beam with laser energy through an outer portion of an eye to a target portion of the eye. The control computer receives an optical density measurement of the outer portion, determines the laser energy according to the optical density measurement, and instructs the laser device to direct the laser beam with the laser energy through the outer portion of the eye to the target portion of the eye.

A target volume of ocular tissue is treated with a laser having a direction of propagation toward the target volume, where the target volume is characterized by a distal extent, a proximal extent, and a lateral extent. A layer of tissue at an initial depth corresponding to the distal extent of the target volume is initially photodisrupted using a femtosecond laser by scanning the laser in multiple directions defining an initial treatment plane. Tissue at one or more subsequent depths between the distal extent of the target volume and the proximal extent of the target volume is subsequently photodisrupted using a femtosecond laser by moving a focus of the laser in a direction opposite the direction of propagation of the laser and then scanning the laser in multiple directions defining an subsequent treatment plane. Photodisruption is repeated at different subsequent depths until tissue at the proximal extent of the target volume is photodisrupted.

Apparatuses and methods for the treatment of glaucoma are provided. The instrument uses either cauterization, a laser to ablate, sonic or ultrasonic energy to emulsify, or mechanical cutting of a portion of the trabecular meshwork. The instrument may also be provided with irrigation, aspiration, and a footplate. The footplate is used to enter Schlemm's canal, serves as a guide, and also protects Schlemm's canal.

Systems, methods, and computer-readable media for integrating and optimizing a surgical suite. An ophthalmic suite can include a surgical console, a heads-up display communicatively coupled with a surgical camera for capturing a three-dimensional image of an eye, and a surgical suite optimization engine. The surgical suite optimization engine can performs a wide variety of actions in response to action codes received from the other components in the surgical suite. The surgical suite optimization engine can be integrated within another component of the surgical suite, can be a stand-alone module, and can be a cloud-based tool.

An ophthalmological device comprises a laser source, an application head having focusing optics and a patient interface, a scanner system and circuit. The circuit is configured to control the scanner system to incise an incision surface, which is symmetrical with respect to the central axis of the patient interface, in the eye tissue, a pulsed laser beam being steered onto treatment points on the incision surface on a first treatment path, and the treatment path being curved while extending around the projection axis of the focusing optics. In the event of a tilt of the eye with respect to the central axis of the patient interface, the circuit determines an apex of a tilted incision surface by a co-tilt of the incision surface corresponding to the tilt of the eye, and determines a transformed treatment path, which extends around the apex and determines treatment points on the tilted incision surface.

A laser surgical system comprises a laser source, scanners, delivery optics, and a computer. The laser source generates a beam of femtosecond laser pulses. The scanners direct focus spots of the beam towards points of a cornea. The delivery optics focuses the focus spots at the points of the cornea. The computer creates an incision in the cornea by instructing the optics and scanners to: direct and focus the focus spots from a posterior corneal surface, through a convex curve and a concave curve, to an anterior corneal surface to form an S-curve incision with a posterior end and an anterior end. The S-curve incision has a substantially non-planar rectangular shape with a longer side that extends from the posterior end to the anterior end and defines a longer direction. A cross-section of the incision in the longer direction exhibits the convex curve and the concave curve.

In certain embodiments, an ophthalmic laser system comprises a laser source, multi-focal optics, scanners, delivery optics, and a computer. The laser source generates a laser beam of ultrashort laser pulses. The multi-focal optics multiplex the laser beam to yield focus spots in a target along a propagation axis of the laser beam. The scanners direct the laser beam in x, y, and z directions. The delivery optics focus the laser beam within the target to form the focus spots in the target along the propagation axis of the laser beam. The computer instructs the scanners and the delivery optics to direct and to focus the focus spots at the target according to a scan pattern.

Laser pulse modulation for laser corneal treatments is used to control the thermal energy imparted to the cornea. The optical energy of the laser pulses may be modulated to reduce or increase the thermal energy, depending upon an expected thermal load or a measured temperature at each position location of the cornea subject to laser treatment. The laser pulse modulation may involve pulse frequency modulation, pulse amplitude modulation, and pulse duration modulation.
