How to make the intraocular pressure after glaucoma filtering surgery more controllable

Abstract

Glaucoma surgery is one of the main methods of glaucoma treatment. In recent years, glaucoma surgery has been greatly developed. Minimally invasive surgical procedures for glaucoma have emerged. Patients and surgeons have also increased their expectations of surgery. However, due to the limitation of surgical controllability, the prediction of postoperative efficacy is still not satisfactory. By analyzing the principles and limitations of the existing surgical procedures, the authors put forward the premise of the controllability of glaucoma extrafiltration surgery as that the intraoperative filtration excess can be restricted, so as to effectively avoid the early postoperative complications such as shallow anterior chamber, hypotony and strong inflammation. And within 1 month after surgery, through the filtration of the bubble and the removal of the adjustable suture, the ideal filtration state is gradually achieved. With the controllable maintenance of intraocular pressure at 1 month after surgery, it is possible to effectively predict the intraocular pressure level of 2 years or longer.
