Two Techniques for Sutureless Intrascleral Posterior Chamber IOL Fixation

PURPOSE: To compare two different techniques for sutureless scleral fixation of posterior chamber intraocular lens (IOL) in patients with insufficient capsule support. METHODS: Of 29 patients, 17 received the needle technique using a 24-gauge needle for the scleral tunnel opening and 12 received the novel trocar technique, in which the scleral tunnel was prepared with a 25-gauge transconjunctival sutureless vitrectomy trocar and a three-piece foldable IOL was placed through clear corneal incision. Visual acuity, intraocular pressure, related complications, and IOL stability were assessed postoperatively. RESULTS: Postoperative visual acuities significantly improved with both techniques (P = .028 and .012, respectively). Postoperative intraocular pressure did not significantly change with either technique. Sufficient IOL stabilities were provided in all patients. Complications were similar in both techniques and none of the complications affected the patients' vision. CONCLUSIONS: Postoperative visual acuity improvement, intraocular pressure changes, and complications were similar in both techniques. [J Refract Surg 2013;29:90-94.]
