In addition, the surgical device comprises a first flexible fluid conduit incorporated in the handle, wherein the first flexible fluid conduit is configured for releasable fluid connection to the rearward end of the cartridge at the forward end of the handle.

Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. An apparatus for delivery of a lens component into an eye may include a housing. The apparatus may further include a plunger at least partially disposed in the housing, wherein the housing comprises an elongated portion and a viscoelastic soft tip at a distal end of the elongated portion, wherein the viscoelastic soft tip has a storage modulus of about 1 megapascal (MPa) to about 300 MPa and a loss module of about 1 MPa to about 300 MPa. The apparatus may further include a drive mechanism operatively coupled to plunger and configured to cause the plunger to translate in the housing. The apparatus may further include a nozzle operatively coupled to the housing through which the plunger delivers the lens component into the eye.

This intraocular lens (IOL) injector cartridge has a proximal opening in a main body for receiving an IOL. The main body has a lumen that extends longitudinally to a distal end having an opening smaller than the IOL. Passage through the lumen compresses or rolls the IOL so that when the distal end is inserted through a small incision in the eye the IOL can be expelled into the capsular bag. The distal end of the cartridge is beveled with a leading tip in front of a trailing heel. The characteristics of the beveled end are such that damage to the IOL is reduced. The bevel may be straight or curved and includes a distal face defined by the thickness of the distal end between the lumen and an exterior surface. The distal face may be flush with the bevel or chamfered. An inner corner angle between the distal face and the lumen is 60 to reduce the chance of scratching the IOL as it passes out of the distal opening.

There is provided an intraocular lens injector including: a hollow body composed of an injector main body 5 having a lens installing portion on which an intraocular lens is installed, and an injection tube 7 attached to a tip part of the injector body 5; a rotary member 8 having a first threaded portion formed thereon and attached to a rear end part of the injector body 5 that constitutes the hollow body, rotatably around an axis of the hollow body; a plunger 9 having a second threaded portion 9c formed thereon, and configured to move through the hollow body in an axial direction of the hollow body; a rod 10 configured to push out the intraocular lens from the lens installing portion by moving through the hollow body in the axial direction of the hollow body together with the plunger 9, wherein a tip side of the plunger 9 is injected into the hollow body in a state in which the first threaded portion and the second threaded portion 9c are meshed with each other, and a rear end side of the plunger 9 is disposed in a state of protruding backward of the rotary member 8.

The present invention relates to an injector system for implanting an intraocular lens into an eye, and to a magazine for such injector system. The present invention provides an injector system for implanting a lens into an eye, comprising the following components: an injector body having a front end and a rear end; a cannula arranged at the front end of the injector body, which provides a transport channel for a lens to be implanted, wherein a lens can be fed into the transport channel via a preferably lateral inlet opening; a magazine with a receptacle area for at least one lens which is securable in the receptacle area by means of a retainer, wherein the magazine is arranged in a manner so that a lens can be fed into the transport channel via the preferably lateral inlet opening; a folding body insertable into the magazine and into the inlet opening, for pushing the lens into the transport channel in a manner so that the lens is at least partially foldable around the folding body; and a slider which is slideably arranged in the injector body, preferably axially, and which can be pushed into the transport channel via the front end of the injector body in such a way that the lens can be ejected from the transport channel. The injector of the invention is particularly suitable for all soft, foldable intraocular lenses. It is easily adaptable to different types of lenses and can be used as a pre-loaded disposable injector.

This intraocular lens (IOL) injector cartridge has a proximal opening in a main body for receiving an IOL. The main body has a lumen that extends longitudinally to a distal end having an opening smaller than the IOL. Passage through the lumen compresses or rolls the IOL so that when the distal end is inserted through a small incision in the eye the IOL can be expelled into the capsular bag. The distal end of the cartridge is beveled with a leading tip in front of a trailing heel. The characteristics of the beveled end are such that damage to the IOL is reduced. The bevel may be straight or curved and includes a distal face defined by the thickness of the distal end between the lumen and an exterior surface. The distal face may be flush with the bevel or chamfered. An inner corner angle between the distal face and the lumen is 60 to reduce the chance of scratching the IOL as it passes out of the distal opening.

The present invention provides a device and method for inserting an IOL into an eye of a patient. The IOL injector is configured to automatically load an IOL into the injector by folding and aligning the IOL into a lens cartridge of the injector without manual manipulation of the IOL by the physician during the procedure. The injector is configured to properly orient and align the IOL within the injector and maintain proper alignment throughout delivery of the IOL to the eye of a patient and thereby ensuring that the IOL is properly positioned and oriented at a predetermined location in the eye.

Aspects of the present invention may include systems and methods for intraocular lens selection using a formula and a deep learning machine to estimate the error of the formula. In an aspect, the disclosure provides a method for intraocular lens selection. The method may include obtaining at least two ocular measurement parameters and a lens selection parameter for an eye. The method may include determining an intraocular lens power based on a formula using the at least two ocular measurement parameters. The method may include determining an estimated error of the formula using a deep learning machine trained on verified post-operative results using intraocular lenses selected by the formula. The method may include adjusting the lens selection parameter based on the estimated. The method may include redetermining the intraocular lens power based on the formula and the adjusted lens selection parameter.

A toric intraocular lens includes a lens body, support portions, and connecting portions for connecting the lens body and the support portions. The lens is housed in an insertion apparatus that includes a tubular apparatus body having an insertion tube for the lens and a plunger for moving the lens. Each of the connecting portions is arranged at a position where the connecting portions face each other across a center of an optical axis of the lens body. One end of the flat meridian of the lens body is located at a position opposite to a position, with respect to an axis that passes through the center and connects the connecting portions, at which the plunger contacts the lens body. An angle between the flat meridian and an axis along which the lens is pushed by the plunger is larger than 0? and equal to or smaller than 90?.
