Quaternary Knot Technique: Suture Knot Burial without Scleral Flap or Incision for Trans-scleral Fixation

Abstract

Abstract Despite the introduction of novel sutureless posterior chamber intraocular lens (IOL) fixation techniques, some conditions still require suture-assisted scleral fixation. If the scleral fixation suture knot is left directly under the conjunctiva, it may become exposed, resulting in an increased risk of endophthalmitis. To avoid this problem, we offer a new alternative, simple, and safe way for burying the end of the suture using knots in this report.
