Intraocular lens

A method of performing laser surgery in a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form an enclosed treatment pattern that is configured to form an enclosed capsulorhexis incision that includes a registration feature, and delivering the enclosed treatment pattern to target tissue in the patient's eye to form in an anterior lens capsule of the patient's eye the enclosed capsulorhexis incision that includes the registration feature. The registration feature is configured so that an edge of the target tissue formed by the enclosed capsulorhexis incision mates with an intraocular lens registration feature on an intraocular lens so as to rotationally register the intraocular lens relative to the registration feature.

Laser assisted cataract surgery
09820886 · 2017-11-21 · ·

Laser assisted cataract surgery methods and devices utilizing one or more treatment laser beams to create a shaped opening in the anterior lens capsule of the eye when performing a capsulorrhexis procedure. A light absorbing agent may optionally be added onto or into the lens capsule tissue, and the treatment laser wavelength selected to be strongly absorbed by the light absorbing agent. Alternatively, the treatment laser wavelength may be selected to be absorbed or strongly absorbed by the tissue itself, in which case no additional light absorbing agent need be used. Visualization patterns produced with one or more target laser beams may be projected onto the lens capsule tissue to aid in the procedure. The devices may be attached to or integrated with microscopes.

APPARATUS FOR PATTERNED PLASMA-MEDIATED LASER OPHTHALMIC SURGERY

Additive manufacturing inside the human eye
11246703 · 2022-02-15 · ·

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.
