Detailed Description
For a clearer understanding of the technical solutions, objects and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings. Wherein the use of the adjectives or adverbs modifiers "horizontal" and "vertical," "inner" and "outer" are merely for ease of reference relative between the sets of terms, and do not describe any particular directional limitation on the modified term. In addition, the terms "first," "second," etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated, whereby features defining "first," "second," etc. may explicitly or implicitly include one or more such features. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.

a) Three channels of ciliary body flat parts are established, namely 3 holes with the diameter smaller than 2mm are punctured on the eyeball wall, one channel is established for perfusion, intraocular pressure is maintained, the other channel is used for guiding optical fiber intraocular illumination, and the third channel is used for feeding intraocular operation instruments such as glass cutting heads, retina forceps, electric coagulation/photocoagulation fibers, flute needles and the like;
b) Vitrectomy, i.e. the maximum removal of vitreous body from the vitreous cavity;
c) Draining subretinal fluid by heavy water or gas-liquid exchange to restore retina;
d) The retina around the laser photocoagulation hole is used for generating inflammatory reaction, so that the retina and a retina pigment cell layer (RPE layer) are tightly adhered (but the inflammatory period is about 2 weeks, so the laser photocoagulation can play a role in adhering the retina after more than 2 weeks);
e) The vitreous cavity is filled, that is, the vitreous cavity is filled with gas, long-acting gas or silicone oil, and the retina is pressed in the vitreous cavity (inner pressing) so that the retina is kept in an attached state at least within 2 weeks after operation (after 2 weeks, the retina and the RPE layer are adhered around the lacerated hole due to the laser photocoagulation part, and the retina cannot be separated again). Because the long-acting gas or silicone oil is lighter than water in density, the postoperative patient needs to keep a low-head posture, and the gas or silicone oil is pressed upwards against the retina.
