Cataract is the first major blind eye disease in the world at present, and the only effective treatment at present is surgery. The handling of cataract lens nuclei is a central link in surgery. The ultrasonic emulsification operation of cataract with small incision or micro incision is the mainstream operation at present, and the basic principle is to emulsify and break nucleus by ultrasonic energy, suck the nucleus of the crystal out of the eyeball by a small incision, and then implant an artificial lens. However, in developing countries such as china, the disease condition of cataract patients gradually worsens to significantly affect the vision and even lose eyesight due to low surgery coverage, late surgery time, high incidence of high myopia and other reasons, and the vision deterioration caused by cataract cannot be corrected by wearing glasses.
The existing cataract surgery is a key step in the surgical process, and the common method is as follows: injecting a proper amount of water or viscoelastic agent between the crystal nucleus and the front and the rear capsular sac to separate the crystal nucleus from the front and the rear capsular sacs, then inserting the snare between the crystal nucleus and the rear capsular sac along the incision, holding a crochet needle by the other hand to enter the anterior chamber, hooking the crystal nucleus to be matched with the snare to pull the crystal nucleus out of the incised tunnel, wherein the viscoelastic agent or water is injected in advance when the crystal nucleus is taken out by the method, and the viscoelastic agent or water is accurately matched by the two hands, otherwise, other tissues in the eye are damaged. With the current increasing demand for quality of life, cataract surgery has progressed from reconstructive surgery to refractive surgery, which requires us to address the hard core removal problem in a safer manner.
