Clinical outcomes of non-torque pattern double running suture technique for optical penetrating keratoplasty.

Objective: To validate non-torque pattern double running suture technique for optical penetrating keratoplasty compared with traditional suture method.

Methods: 56 patients (56 eyes) undergoing optical penetrating keratoplasty were divided into two groups. The experimental group (28 cases) underwent non-torque pattern double running suture technique, and the control group (28 cases) underwent interrupted suture.
