To ensure consistency, the same surgeon (Zhong Haibin) performed all the surgeries under an operating microscope. The surgical technique was described as follows. After administration of conventional retrobulbar anesthesia, all patients underwent 23G or 25G three-port pars plana vitrectomy. The dislocated lens was captured in the anterior chamber with the help of a chandelier fiber for extraction, and intraocular lens (IOL) implantation was performed (Alcon, CZ70BD) with upper and lower loop fixation. Pupilloplasty was performed if the pupil was still larger than 4 mm after 1.0 ml camcoline was injected into the anterior chamber (AC).Iris suturing was performed with 10–0 polypropylene sutures on a round-bodied needle (Alcon Laboratories, Inc., Sinking Spring, PA, USA). Na-HA (1.7%, Bausch & Lomb Co., Ltd., Shang Dong, China) 0.15- A total of 0.2 mL was injected into the AC to form sufficient operating space and protect the corneal endothelium. From the surgeon's right-hand corneal limbus, one incision was created along the axis of the area of iris defect, a needle was inserted into the AC through the incision (Fig. Illustration of the surgical steps of pupilloplasty surgery. A needle was inserted from the corneal limbus into the anterior chamber. The needle going through the iris was assisted using a microhook (
