Summary

Pterygium is a wing-shaped fibrovascular tissue that has proliferated onto the cornea. Ultraviolet radiation and hot, dusty, windy, dry, smoky environments are regarded as risk factors for pterygium . Surgical removal is the treatment of choice, and surgical wound intraoperative and inflammatory response postoperative have been considered two of the most significant factors that can increase the recurrence rate of pterygium. Low-Temperature Plasma Surgery System(LTP), avoids causing burn injuries to patients, has been introducing into minimally invasive surgery. The mechanism by which this equipment stop bleeding and abolish tissue is to directly occupy the injury with the formed blood clots, plasma flows close the vessel and plasma active particles cause physical and chemical reactions with tissue. The different levels of energy density of plasma can affect the bacteria, cells and cancer cells and even to death, therefore it is widely used in the disinfection of medical devices, dental root canal therapy, skin disease treatment and surgical wound disinfection. Whether it's possible to apply the advantages and benefits of plasma technology in ophthalmic surgery? Like pterygium surgery? However, there is no research to answer until now. In this study, the investigators retrospectively observed the efficacy, postoperative discomfort, inflammation, complications, and recurrence rates in a group of patients for whose LTP was used in pterygium excision and wound hemostasis. The investigators Observe the clinical benefits of LTP in pterygium surgery and find the facilitates and problems it need to be addressed reasonably.
