The ophthalmic laser medical endoscope system consists of a laser microscope endoscope lens and a main unit. The laser micro endoscopic lens integrates imaging, illumination, and intraocular laser, with a diameter of 0.88mm and a focal length of 1-20mm. The operation method is the same as that of general optical fibers, and its three functions can be freely selected without changing the handle. The host includes a high-resolution TV screen, TV camera, xenon light source, and 810nm wavelength semiconductor diode laser. There is not much difference between using a medical endoscopic system for surgery and general vitrectomy. Due to its endoscopic function, it is possible to perform some operations that are difficult to complete in ordinary vitreoretinal surgery under screen monitoring. If the current situation (such as corneal opacity, pupil constriction, posterior capsule opacity, or intraocular gas) prevents or when conventional methods (such as under a surgical microscope) do not allow for proper visualization of certain structures in the eye, under the guidance of an endoscope, surgery can be performed near the periphery of the retina, the flat area, the ciliary body, and the posterior iris region without compressing the sclera to complete the anterior segment PVR dissection and simultaneous intraocular laser photocoagulation. Medical endoscopes are currently mainly used for glaucoma ciliary body photocoagulation and vitreoretinal surgery. The use of this instrument to treat glaucoma and various types of vitreoretinal diseases has achieved good results. The use of ciliary body photocoagulation can effectively reduce intraocular pressure, which can be lowered by 57-65%. In vitreoretinal surgery, vitrectomy, retinal photocoagulation, and other procedures can be performed under direct vision using a microscope, without being affected by the anatomical location or anterior segment of the eye. Due to the use of lasers in endoscopic lenses, the number of times instruments enter and exit the eye can be reduced during retinal photocoagulation. After surgery, it is convenient to use an endoscope to check for iatrogenic retinal tears without the need for indirect inspection glasses.

Some resolutions are lower, especially when working at close range. A new slope index endoscope solves this problem. It has high resolution and can provide good resolution even at very close distances. In the past, the subretinal operation during vitrectomy was performed blindly because it was viewed through the retina. With this endoscope, there is no need for omental incision. It can be introduced into the subarachnoid space through a scleral incision and choroid incision, and other surgical instruments can be introduced through another similar incision. Operations under the omentum can be performed under direct visualization with an endoscope. The result is that doctors can perform fairly precise operations. It is possible to finely peel off the subretinal membrane between the pigment epithelium and the neuroepithelium without damaging these two layers of structure. It is extremely difficult to identify the nourishing arteries of the choroid and coagulate them with light during routine subretinal procedures. This technique is a significant improvement over conventional surgery.
