To evaluate the efficacy of intraocular lens (IOL) cushion plate technology in reducing corneal endothelial cell loss during hard-core cataract surgery compared with conventional ultrasonic emulsification.
Seventy-six patients with hard-core cataracts who underwent surgery at our institution from April 2019 to June 2022 were included. The patients were divided into an observation group (IOL cushion plate technology, 38 patients) and a control group (conventional ultrasonic emulsification, 38 patients). Surgical outcomes, including the corneal endothelial cell loss rate, best corrected visual acuity (BCVA), and central corneal thickness (CCTc), were compared between the two groups.
Preoperative patient characteristics were similar between the groups. Postoperatively, both groups demonstrated similar BCVA and CCTc values on days 7 and 30. However, compared with the observation group, the control group presented a significantly greater rate of corneal endothelial cell loss on postoperative days 7 and 30 ( < 0.05). Intraoperative complications and postoperative complications were notably greater in the control group ( < 0.05). The observation group had reduced ultramilk time and total energy consumption ( < 0.05).
IOL cushion plate technology offers advantages in preserving corneal endothelial cells during hard-core cataract surgery, potentially improving surgical safety and efficacy.
评估人工晶状体（IOL）缓冲板技术在硬核白内障手术中与传统超声乳化术相比减少角膜内皮细胞损失的疗效。
纳入2019年4月至2022年6月在本机构接受手术的76例硬核白内障患者。将患者分为观察组（IOL缓冲板技术，38例）和对照组（传统超声乳化术，38例）。比较两组的手术结果，包括角膜内皮细胞损失率、最佳矫正视力（BCVA）和中央角膜厚度（CCTc）。
两组术前患者特征相似。术后第7天和第30天，两组的BCVA和CCTc值相似。然而，与观察组相比，对照组在术后第7天和第30天的角膜内皮细胞损失率显著更高（<0.05）。对照组的术中并发症和术后并发症明显更多（<0.05）。观察组的超乳时间和总能量消耗减少（<0.05）。
IOL缓冲板技术在硬核白内障手术中在保护角膜内皮细胞方面具有优势，可能提高手术安全性和疗效。
