The invention relates to an injector (20) for inserting an intraocular lens (1) into an eye (10), having an injector axis (26), an injector body (41) delimiting a folded chamber (21) and having an injector tip (22) with an opening (23), and having a plunger (42), and a plunger arranged longitudinally displaceably in the injector body and configured to deliver the intraocular lens from the folding chamber (21) into the injector tip (22) and then out of the injector via the opening (23) by movement of the plunger in an insertion direction (40) of the injector, the injector tip is beveled in the region of the opening (23) by the injector tip having an end face (27) which directly adjoins the opening and the normal of which encloses an end face angle with the injector axis which differs from 0 DEG, the injector tip having at least one helical groove (27) on the inner wall thereof, the at least one helical groove is configured to pivot the intraocular lens relative to the injector axis in an injector circumferential direction (44) when the intraocular lens passes through the injector tip.

The present invention provides an innovative system for correcting aphakia in the absence of a natural capsular bag. It comprises a foldable artificial capsular bag made of biocompatible material, traversed by polypropylene 6-0 threads extended by thin pliable needles, allowing stable and precise scleral fixation. A specialized injector equipped with a cartridge having a single longitudinal opening facilitates insertion by positioning the threads without overlapping. This cartridge closes firmly after folding, ensuring stability during injection, while being compatible with standardized injectors. An ergonomic intraoperative stabilization headband, positioned on the forehead of the patient, holds the injector in place by virtue of inverted supports, improving surgical precision and reducing unnecessary manipulations. This system simplifies surgery, reduces complications and optimizes the visual results.

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.

The present application relates to a kind of bionic human eye vision system, belong to the cross-disciplinary technical field of biomedical and optics.The whole system is placed on unified optical platform, including white light source, linear motorized translation stage, observed target, band-pass filter, achromatic lens, polaroid, electrically controlled diaphragm, artificial lens, scanning lens, two-dimensional galvanometer, beam splitter, beam quality analyzer, full mirror, lens, high-sensitivity photodetector and computer.The advantage is novel structure, through high-sensitivity detector and feedback control circuit can realize automatic adjustment system light quantity size, prevent overexposure, through adjusting artificial lens and two-dimensional galvanometer can realize detecting different distance, different angle object, so as to simulate the basic function of human eye, can gather and process image in complex environment.
