Torque-free bicontinuous suture method for corneal transplantation

Abstract

The invention discloses a torque-free double continuous suture method for corneal transplantation. In the torque-free double continuous suture method for corneal transplantation, an initial reference suture is established from the first step, and then each step is based on the reference suture of the previous step. The stitches are sutured regularly, and a reference is set for the next suture, which ensures that each inner suture angle and outer suture angle are 90° and 45°, which overcomes the randomness of double continuous suture in the past and makes the suture layout after surgery It is more beautiful and reasonable, reduces the twisting force of the graft and the implant bed, reduces postoperative astigmatism, is safer than the traditional method, and avoids the risk of cutting the suture during the operation, and the suture knot is buried in the junction of the graft and the implant bed. In the incision, it avoids postoperative complications caused by exposed thread knots, reduces the risk of suture breakage caused by turning sutures after surgery, and improves vision better than intermittent sutures, providing a more effective and simple method for clinical use. new method.

Description

technical field [0001] The invention relates to the technical field of corneal suture, in particular to a torque-free double continuous suture method for corneal transplantation. Background technique [0002] During keratoplasty, the tissue anatomical alignment, matching degree, suturing technique and suture method of the graft and implant bed are the main causes of postoperative astigmatism. 1. After improving the quality of corneal surgery and improving the level of suture technology, the suture method is the main cause of astigmatism. Large postoperative astigmatism may lead to a decrease in postoperative visual acuity and affect the recovery of postoperative vision. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a torque-free double continuous suture method for corneal transplantation. Starting from the first step, an initial reference suture is established, and then each st...
