摘　　要：Phacoemulsification is a commonly used surgical method in cataract surgery. This paper observes and compares the surgical efficacy of three incisions of different length for phacoemulsification to identify the optimal method for cataract surgery. Ninety patients were enrolled in the present study and divided into three groups. The 1.8-mm group received Bausch ＆ Lomb MI60 foldable intraocular lens （IOL） implantation （n=30）, 3.2-mm group received Bausch ＆ Lomb Akreos AO foldable lens implantation （n=30）, and 5.5-mm group received Alcon TYPE 05 rigid IOL implantation （n=30）. Visual acuity, Oculyzer-based anterior segment analysis, and corneal endothelial cell count before surgery, and 3, 7, 30, and 90d after surgery were recorded and compared. Pseudophakic accommodation three days, one week, one month, and three months after surgery was determined. Intraoperative ultrasound time and ultrasonic energy were recorded. It was finally concluded that for phacoemulsification with the same phaco tip, a 1.8-mm microincision can lead to quicker recovery of visual acuity, more stable astigmatism, and higher pseudophakic accommodation than conventional incision.Phacoemulsification is a commonly used surgical method in cataract surgery.
