Appropriate hemostasis is a fundamental principle of modern surgery. The operations of the eyelids are very demanding in terms of precision of the equipment used to induce hemostasis. Nowadays one of the most frequently used methods for inhibition of intraoperative bleeding is bipolar electrocoagulation. However, this method has its limitations, of which the process of charred tissue adhesion to the tip of the probe, which significantly hinders the surgery, is the most vital one. With the increasing use of lasers in medicine, more and more often systems of laser contact cutting and coagulation are used. Unfortunately, despite the higher precision of performance, they have the same drawback as electrocoagulation, namely the adhesion of charred tissue.

The efficacy of bipolar contact electrocoagulation is compared with the non-contact method using a diode laser during dermatochalasis surgery of 60 eyes in 30 patients. There have been shown a clear shortening of time to achieve hemostasis in the eyes treated with laser coagulation.With no contact with the bleeding tissue, laser coagulation precisely and without delay inhibits bleeding, which significantly shortens the time of surgery.

Study showed a higher efficiency of contactless laser coagulation versus contact, bipolar electrocoagulation. With no contact with the bleeding tissue and the specific properties of the wavelength of 980nm, laser coagulation foci inhibit bleeding precisely and without delay, which significantly shortens the surgery time. Cost-efficiency of diode lasers as well as no need for sterilization of the laser probe further enhance the advantages of this method, which works better than electrocautery in the surgery of the eyelids.
