Phacoemulsification (PE) is a gold standard method of cataract surgery. PE causes structural changes in the macula of the eye. The aim was to determine the amount of ultrasound (US) energy applied during PE, the change in thickness of the intraretinal layers, and the correlation between the applied US energy and the change in the thickness of the intraretinal layers in five predefined areas of the macula. This prospective study included 102 eyes of 79 consecutive subjects without other eye or systemic diseases that can affect the eyes submitted to PE. The macular layer thickness was measured on the day of PE (day 0) and at 7, 30, and 90 days after PE using an OCT device. Recorded images were based on posterior pole asymmetry analysis. Statistically significant correlations of applied US energy and the change in thickness of retinal layers were found 90 days after PE in 6 out of 10 macular layers in different macula regions. The results suggest interconnections between US energy spent during PE and the change in the thickness of individual retinal layers of the macula, in different ranges, unevenly, in five defined areas of the macula.
超声乳化白内障吸除术（PE）是白内障手术的金标准方法。PE会导致眼部黄斑区结构发生变化。目的是确定PE过程中施加的超声（US）能量、视网膜内层厚度的变化，以及在黄斑区五个预定义区域中施加的US能量与视网膜内层厚度变化之间的相关性。这项前瞻性研究纳入了79例连续受试者的102只眼睛，这些受试者没有其他可影响接受PE手术眼睛的眼部或全身性疾病。使用光学相干断层扫描（OCT）设备在PE当天（第0天）以及PE后7天、30天和90天测量黄斑层厚度。记录的图像基于后极不对称分析。在PE后90天，在不同黄斑区域的10个黄斑层中的6个中发现施加的US能量与视网膜层厚度变化之间存在统计学显著相关性。结果表明，在PE过程中消耗的US能量与黄斑区五个定义区域中黄斑单个视网膜层厚度的变化之间存在不同范围、不均匀的相互联系。
