Background
Implantable Contact Lenses (ICL) are currently a safe, high-end solution for myopia correction. ICL implantation is also known as intraocular lens implantation. An ICL intraocular lens is a soft intraocular lens that can be placed in the anterior safe zone of the lens, is only about 50 microns thick, is thinner than the diameter of hair, and has superior post-operative vision to frame glasses, contact lenses, and other refractive correction techniques performed on the cornea. Unlike laser and other procedures for cutting corneal tissue, ICL implantation, which does not cut the cornea, implants a lens into the eye by minimally invasive surgery without damaging the cornea, is an effective method for treating high myopia, however, the most common post-operative response is increased intraocular pressure, which is mainly caused by the injection of viscoelastic into the eye during surgery, and a trace amount of viscoelastic remains in the eye after surgery. Therefore, methods for cementless ICL implantation have recently been proposed. Although the problem of viscoelastic agent residue is solved in the non-viscoelastic agent ICL implantation, various instruments are needed to be matched for use in the operation, and the operation is complicated.

Drawings
Fig. 1 is a schematic structural view of an ICL positioning hook with perfusion according to the present invention.
Detailed Description
The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 1, the utility model provides a ICL positioning hook that area was filled, include:
a positioning hook body which is provided with a handle 1 and a positioning part 2;
a perfusion part which comprises a perfusion inlet 3, a perfusion channel 4 and a perfusion outlet 5 which are communicated in sequence;
the perfusion channel 4 is arranged in the positioning part 2, the perfusion outlet 5 is arranged at one end of the positioning part 2 for adjusting the intraocular lens and is opened on the side wall of the positioning part, and the perfusion inlet 3 is arranged at the joint of the positioning part 2 and the handle 1.
When the ICL implantation is used for myopia treatment, if the perfusion liquid is not continuously filled, the liquid in the anterior chamber of the eye flows out when the adjustment is carried out in the operation, the water level of the anterior chamber becomes shallow, so that the operation cannot be carried out; furthermore, the use of consumables such as viscoelastic agent for maintaining the anterior chamber during surgery can be reduced. Reducing consumables is a better way for the patient and, without the use of viscoelastic, reduces the incidence of postoperative complications such as elevated intraocular pressure.
