A comparison study of corneal topographic changes following 20-, 23-, and 25-G pars plana vitrectomy

Abstract

Twenty-three-gauge and 25-gauge transconjunctival sutureless vitrectomy did not induce topographic corneal changes following surgery, whereas 20-G vitrectomy was found to induce transient topographic corneal changes that had returned to preoperative levels at three months postoperatively.
