Here, we conducted a nonrandomized clinical trial aims to evaluate and compare the prognosis of visual function in children of these two types of IOL implantation over a three-year postoperative period.

All surgeries were performed by the same surgeon (J.Y.) using a standardized surgical technique (phacoemulsification for cataract extraction+ IOL implantation + anterior vitrectomy) under general anesthesia. Scleral tunnel incision was created firstly. Thereafter, 5.0-5.2mm anterior capsule capsulorrhexis, and cataract aspiration were performed. A single-piece hydrophobic acrylic IOL (SN6AT3-T9) was implanted into the capsular bag. After the corneal incision was closed with 10-0 sutures, a posterior capsulectomy of 3-4 mm and anterior vitrectomy were performed through the pars plana using 25-gauge instrumentation with high cutting frequency (3,000 to 4,000 cuts per minute) and low aspiration pressure (300 to 350 mm Hg) in all eyes. A 3.5-4.0 mm posterior capsule capsulorrhexis and anterior vitrectomy were performed in patients.
