Patients who come to the clinic with under-eye bags are very clear about the difference between external and internal eye bag surgery. They know that the external cut will leave a scar near the root of the eyelashes, while the internal cut is inside the eyelid and the cut is not visible. However, it is not very clear about the difference between internal and laser lipolysis eye bag removal, thinking that they are the same thing. However, laser lipolysis eye bag removal and internal incision are completely different. First of all, internal cutting is surgery, and surgery has the risks and complications of surgery, such as bleeding, infection, poor healing of the incision, scarring leading to eye discomfort, accidental bleeding leading to blindness due to under-eye pressure, etc. Secondly, the need for gauze and pressure bandaging for 24 hours after endoscopic surgery requires accompanying someone to the hospital as well as care at home, which brings inconvenience to life. It is especially difficult for patients with limited mobility to come for surgery. After the surgery, there will be bruising and bruising, which will gradually fade away in about 1 week. Furthermore, the internal cut method is to cut out the whole protruding fat, if too much is cut, post-operative sunkenness will occur and the eyes will appear old. Laser lipolysis for eye bag removal is a new generation of minimally invasive surgery, not surgery. The method is to send the light guide fiber into the fat mass through a small hole of 0.2mm and use the energy emitted by the laser to specifically dissolve the fat cells without harming other tissues of the eyes, effectively preserving the basic structure of the fat perimeter of the eyes, and no sunken, aged appearance will occur. Secondly, the laser used in our hospital also has a hemostatic function to avoid bleeding while lipolysis, which also avoids all the risks and complications of endoscopic surgery. Moreover, the most convenient thing for patients is that they do not need to be bandaged after the treatment, so they do not need to be accompanied and will not cause inconvenience to their daily work life. Laser lipolysis to remove under-eye bags is a minimally invasive treatment method that does not break the ring of tissues in the under-eye bag area, which is another point that distinguishes it from internal incision: laser lipolysis can be done repeatedly, with an interval of 3 months. However, after the internal surgery, the trauma is scarred healing, and the internal surgery again is traumatic and difficult, and the result is not ideal.
