: Cataract phacoemulsification surgery provides excellent refractive results; however, it also elicits changes in the posterior segment of the eye. This study aimed to determine changes in retinal parameters measured by spectral-domain optical coherence tomography (SD-OCT) and OCT angiography (OCTA) after an uncomplicated cataract surgery, including the impact of effective phacoemulsification time (EPT). : The study included 44 patients without retinal abnormalities, followed up after unilateral uncomplicated cataract phacoemulsification in a single ophthalmological unit. Patients were evaluated for the following parameters at baseline and at 2 weeks, 3 months, and 12 months after the surgery: best corrected visual acuity, central retinal thickness (CRT), average central retinal thickness (CRTA), central retinal volume (cube volume (CV)), vessel density central (VDC), vessel density full (VDF), vessel perfusion central (VPC), and vessel perfusion full (VPF). The EPT recorded at each procedure was used as a covariant for the evaluation of changes in retinal parameters after the surgery. Analysis included 44 eyes for SD-OCT and 17 for OCTA evaluation, according to adopted scan quality thresholds. : A significant increase in CRT, CRTA, and CV was noted at each follow-up point compared with baseline. The rising tendency was observed in the first 3 months after the surgery, with a decline over the subsequent months. The VPF parameter showed a stable improvement after the surgery. The analysis of covariance did not confirm any significant effect of the EPT on variations in CRT, CV, CRTA, VDC, and VPF and there was a weak effect on the VDF parameter. : Uncomplicated cataract surgery results in an increase in retinal thickness and volume in the first few months after the surgery, followed by a spontaneous decline in these parameters in the subsequent months. A long-standing improvement is noted in the VPF parameter.
白内障超声乳化手术能带来出色的屈光效果;然而,它也会引发眼后段的变化。本研究旨在确定单纯性白内障手术后通过光谱域光学相干断层扫描(SD - OCT)和光学相干断层扫描血管造影(OCTA)测量的视网膜参数变化,包括有效超声乳化时间(EPT)的影响。
该研究纳入了44例无视网膜异常的患者,在单一眼科单元接受单侧单纯性白内障超声乳化手术后进行随访。在基线以及术后2周、3个月和12个月对患者进行以下参数评估:最佳矫正视力、中心视网膜厚度(CRT)、平均中心视网膜厚度(CRTA)、中心视网膜体积(立方体积(CV))、中心血管密度(VDC)、全血管密度(VDF)、中心血管灌注(VPC)和全血管灌注(VPF)。每次手术记录的EPT用作评估术后视网膜参数变化的协变量。根据采用的扫描质量阈值,分析包括44只用于SD - OCT评估的眼和17只用于OCTA评估的眼。
与基线相比,各随访点的CRT、CRTA和CV均显著增加。术后前3个月观察到上升趋势,随后几个月有所下降。VPF参数术后显示出稳定改善。协方差分析未证实EPT对CRT、CV、CRTA、VDC和VPF变化有任何显著影响,对VDF参数有微弱影响。
单纯性白内障手术在术后最初几个月会导致视网膜厚度和体积增加,随后几个月这些参数会自发下降。VPF参数有长期改善。
