20230255471 · 2023-08-17 ·

Systems and methods are provided for in vivo pre-surgical characterization of lenses, such as cataractous lenses. A method comprises obtaining an electromagnetically-measured value related to the axial thickness of the lens, obtaining an ultrasound-measured value related to the axial thickness of the lens, calculating a relationship value based upon the electromagnetically-measured value and the ultrasound-measured value, and determining a mechanical property value based upon the calculated relationship value. The mechanical property may relate to lens hardness, rigidity, or density, or the amount of energy for a phacoemulsification procedure. A system may comprise an optical interferometer for measuring data to obtain the electromagnetically-measured value and an ultrasound biometer for measuring data to obtain the ultrasound-measured value.

LASER CATARACT SURGERY USING SPIRAL LENS SEGMENTATION PATTERN
20230255829 · 2023-08-17 ·

In a cataract procedure, a new geometry of a lens segmentation pattern reduces the required phacoemulsification energy to remove the lens. The lens segmentation process employs a three-dimensional spiral lens segmentation pattern that resembles a spiral staircase or a spiral ramp, to incise a vertical cylindrical volume of the lens into a three-dimensional spiral that can be more easily removed. The segmentation patter is formed by scanning the laser focal spot in a layer by layer manner, each layer including a closed curve corresponding to the outer boundary of the segmentation volume, and a filled area inside the closed curve forming a horizontal step of the spiral staircase. The horizontal steps of vertically adjacent layers are offset by an offset angle, creating the spiral lens segmentation pattern that form a spiral volume.

Method for creating incision to improve intraocular lens placement

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.

SUB-NANOSECOND LASER SURGERY SYSTEM UTILIZING MULTIPLE PULSED LASER BEAMS

A system for laser ophthalmic surgery includes: a single laser source, under the operative control of a controller, configured to alternatively deliver a first treatment laser beam and a second treatment laser beam. The first treatment laser beam has a pulse energy of 10 to 500 μJ. The second pulsed laser beam has a second pulse energy of about 0.1 to 10 μJ, lower than the first treatment laser beam. An optical system focuses the first treatment laser beam to a first focal spot and directs the first focal spot in a first treatment pattern into a first intraocular target. The optical system also focuses the second treatment laser beam to a second focal spot and direct the second focal spot in a second treatment pattern into a second intraocular target. The first intraocular target and second intraocular target are different.
