Traumatic iridodialysis caused by blunt eyeball trauma is often accompanied by lens dislocation. Blunt ocular trauma causes the sphincter pupillae muscle to stretch, posterior movement of the lens/iris diaphragm, and an acute elevation in intraocular pressure, and consequent tearing of the tissues near the anterior chamber angle. Abnormalities in pupil size, distortion, and eccentricity affect vision and cause symptoms such as photophobia, monocular diplopia, debilitating glare, and halos.Medications for traumatic iridodialysis are ineffective; however, the condition can be repaired by pupilloplasty surgery. Currently, pupilloplasty technique is suitable for a wide range of applications, including iris abnormalities secondary to intraocular trauma or surgery, and angle‑closure glaucoma [Significant ocular blunt trauma necessitating iris reconstruction may also result in cataracts and sub- or complete dislocation of the lens. The usual treatment for a combined iris and lens capsule deficiency is iris prosthetic implantation via scleral sutures or iridoplasty with scleral-fixated IOL [The purpose of this retrospective study was to compare the clinical outcomes of 45 eyes with traumatic iridodialysis and traumatic lens dislocation treated by two knotting methods performed in pupilloplasty. In a wet lab, we further evaluated the learning curve of ophthalmology residents’ abilities to perform two knotting methods during pupilloplasty.
