The application discloses a light treatment equipment for after-cataract, and belongs to the technical field of medical devices. The light treatment equipment adjusts the emission direction of treatment light by using a light guide module to make the treatment light project to an intraocular target area. The light shaping module is used to shape the emission spot of the treatment light to match the annular anatomical structure of the equatorial part of the lens capsule bag. During the cataract intraocular lens implantation surgery, the light treatment equipment emits treatment light to precisely irradiate the intraocular target area, thereby inducing the apoptosis of epithelial cells in the anterior subcapsular area and the equatorial area of the lens in the intraocular target area. The light treatment equipment does not cause damage to the surrounding tissue structure, can greatly reduce complications, and can effectively prevent and effectively and precisely treat after-cataract.

The utility model relates to the field of medical apparatus and instruments, and discloses a nursing plate for implanting an intraocular lens with a lenticular eye, which comprises a nursing plate provided with a combined mechanism; the combined mechanism comprises a chassis, a rotating shaft, a waste collecting barrel, a lower shaft body, an upper shaft body, a square block, a threaded cylinder, a sleeve disc, a connecting rod and a limiting rod; the rotating shaft is rotatably installed on the base plate, the waste collecting barrel is fixedly installed on the rotating shaft, the lower shaft body and the upper shaft body are fixedly connected with the base plate and the nursing plate respectively, the square block is fixedly connected with the lower shaft body and clamped with the upper shaft body, the threaded cylinder is in threaded connection with the lower shaft body and the upper shaft body, and the sleeve plate is fixedly connected with the limiting rod. And the limiting rod is clamped with the connecting rod. The nursing tray has the following advantages and effects that the waste collecting barrel and the nursing tray can be conveniently combined for use, and when the nursing tray needs to be used, the limiting of the waste collecting barrel can be relieved, and the waste collecting barrel can be rotated out for use.

The invention discloses an intraocular lens implanting device and a leading-in head. The intraocular lens implanting device comprises the leading-in head and an injector. The lead-in head comprises a pushing and injecting area, a transition area and a loading area, one end of the transition area is communicated with the pushing and injecting area, and the other end is communicated with the loading area; the loading area comprises a bearing part and a bending part; one end of the bearing part is connected with the transition area, the other end of the bearing part is rotationally connected with the bending part, the bearing part and the bending part are respectively provided with a main groove and an auxiliary groove which are used for bearing an artificial lens and an upper supporting loop, and the main grooves are communicated with the auxiliary grooves. The push injector comprises a push rod and an outer cylinder, and the push rod is arranged in the outer cylinder and can slide to the push injection area of the guide-in head along the outer cylinder. The main groove and the auxiliary groove are designed in the loading area of the leading-in head to load the intraocular lens in a partitioned mode, loading is convenient and fast, rotation or overturning is not prone to occurring in the pushing and injecting process, the situation that the intraocular lens is clamped or blocked is reduced, and the intraocular lens can be safely implanted into the human eyes conveniently.

A system, method, and apparatus for performing intraocular lens implantation using real-time surgical reference indicium are disclosed. An example method includes recording a patient specific pre-operative still image of an eye prior to cyclorotation of the eye when a patient lies down for surgery and generating at least one real-time multidimensional visualization of at least a portion of the eye for display. The method further includes using the patient specific pre-operative still image to at least produce at least one virtual surgical reference indicium including an ocular natural vertical axis of the eye and align the at least one virtual surgical reference indicium to the eye in conjunction with the real-time multidimensional visualization of at least a portion of the eye. The patient specific pre-operative still image is captured under a dilation condition selected from the group consisting of natural dilation, chemical dilation, and no dilation.

This invention is Preloaded An intraocular lens implantation system is disclosed, comprising: a barrel; Plunger , Push knob , and cartridge and cartridge An introduction passage is provided in the ocular lens, and a mounting groove for accommodating an intraocular lens is provided in the introduction passage, and a removable lens limiting member is provided in the mounting groove, and the lens limiting member includes a limiting plate, and the limiting plate Plunger In the direction of movement Plunger A stopper is provided to prevent the extension of the restricting plate into the introduction passage. Plunger A straight prevention support pillar is provided on the side in the direction of movement of the Preloaded The intraocular lens implantation system integrates rotation and thrust, has high implantation accuracy, a limiting plate prevents the lens from inverting, and a stopper and straightness prevention support column prevent the front loop from coming out straight. When the intraocular lens is implanted, the two loops hold the optical region and maintain a position where it is covered above it, preventing deformation of the intraocular lens and ensuring its position is stable. It is also easy to operate and efficient.
