To assess the risk factors for endothelial cell loss after phacoemulsification with implantation of intraocular lens according to anterior chamber depth (ACD).
This prospective study included 94 eyes of 94 patients undergoing phacoemulsification cataract surgery. To assess the risk factors for corneal endothelial cell loss, we examined seven variables at 1 day, 1 week, 6 weeks, and 12 weeks postoperatively in each ACD-stratified group.
Multiple linear regression analysis showed that the only variable influencing the percentage decrease in corneal endothelial cell density throughout the postoperative follow-up period in the long ACD group (ACD III) was nucleosclerosis. The variables influencing the percentage decrease in corneal endothelial cell density in the short ACD group (ACD I) at one day and one week postoperatively were corneal incisional tunnel length and nucleosclerosis.
Risk factors for endothelial cell loss after phaoemulsification were different according to ACD. Long corneal tunnel length can be one of the risk factors for endothelial cell loss in short ACD eyes.
根据前房深度（ACD）评估白内障超声乳化吸除联合人工晶状体植入术后内皮细胞丢失的危险因素。
这项前瞻性研究纳入了94例接受白内障超声乳化手术患者的94只眼。为评估角膜内皮细胞丢失的危险因素，我们在术后1天、1周、6周和12周对每个ACD分层组的7个变量进行了检查。
多元线性回归分析显示，在长ACD组（ACD III）术后整个随访期内，影响角膜内皮细胞密度降低百分比的唯一变量是核硬化。在短ACD组（ACD I）术后1天和1周时，影响角膜内皮细胞密度降低百分比的变量是角膜切口隧道长度和核硬化。
白内障超声乳化术后内皮细胞丢失的危险因素因ACD而异。长角膜隧道长度可能是短ACD眼内皮细胞丢失的危险因素之一。
