Systems, methods, and apparatuses for inserting an intraocular lens (IOL) into an eye, are provided. The apparatus comprises an IOL cartridge comprising a nozzle, a compartment, a plunger, and a plunger case. The nozzle is in fluid communication with the compartment, and the plunger case is in fluid communication with the compartment. The plunger is disposed within the plunger case. The plunger case includes flexible members extending from an outer surface of the plunger case. The IOL cartridge is configured to removably attach to a handpiece.

Intraocular lens delivery devices and methods of use.

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.

Delivery devices for delivering an ophthalmic device into an eye. In some embodiments the delivery devices are adapted to deliver an intraocular lens into an eye.

An intraocular lens inserter can include an energy storage portion, an actuator portion, and a lens support portion. The energy storage portion can include a compressible energy storage device, such as a compressible fluid, springs, and other devices. The inserter can include an actuator portion operating with a substantially incompressible fluid, such as liquids or other noncompressible fluids. The actuator can be configured to provide an operator with control over the release of energy from the energy storage portion so as to move a plunger for the discharge of a lens from an intraocular lens cartridge.

Various systems and techniques for inserting an intraocular lens are disclosed. In particular implementations, a system and a technique for inserting an intraocular lens may include the ability to move, in response to a force being applied in a first direction along a longitudinal axis, a first plunger tip along the longitudinal axis and into a delivery cartridge to fold an intraocular lens and move in a second direction along the longitudinal axis in response to the applied force being reduced. The system and the technique may also include the ability to engage a second plunger tip and move, in response to a force being applied in the first direction along the longitudinal axis, the second plunger tip along the longitudinal axis and into the delivery cartridge to insert the intraocular lens.

An insertion system for inserting an IOL int a patient's eye is provided. The insertion system includes a pusher and an introducer sheath with a back housing and a front housing. The front housing includes a longitudinally extending IOL rolling member with a proximal section, an intermediate section, a distal section and a longitudinally extending lumen defined by an upper face and a lower face. The lower face has opposing inner peripheral edges. The radius of curvature of the upper face and the lower face decreases from the proximal section to the distal section and the distance between the opposing inner peripheral edges decreases from the proximal section to the distal section.

The invention relates to an apparatus and method that provides hydraulically assisted delivery of intraocular lenses (IOL) from a insertion tool. The IOL insertion system having an insertion rod with a tube having a first end and a second end, a piston head affixed to the insertion rod and positioned between the first and second end, a hydraulic chamber, an aspiration line communicatively connected to the hydraulic chamber, and at least one valve in fluid communication with the aspiration line, wherein the insertion rod moves in response to the displacement of hydraulic fluid within the hydraulic chamber.

An intraocular lens (IOL) injector is configured for single hand operation and employs a compressed gas to provide a motive force to present an IOL to a surgical site. The IOL injector includes a mechanical brake coupled to a plunger to preclude translation of an IOL absent operator input. The mechanical brake provides for selectively varying the speed and translation of the plunger, and hence IOL during presentation of the IOL to a patient. The IOL injector can also include at least a first stop, which halts movement of the plunger at a predetermined position. The at least first stop is then moved to a passing position, thereby allowing further operator controlled translation of the plunger to present the IOL to the surgical site.
