To evaluate the effect of neodymium: yttrium–aluminium-garnet laser posterior capsulotomy (Nd:YAG-caps) on retinal thickness and microcirculation by wide-field swept-source optical coherence tomography (WF SS-OCTA). 35 eyes of 35 patients who had posterior capsule opacification (PCO) were included, all patients underwent Nd:YAG-caps and had complete follow-up results available. The 12 × 12 mm macular region was examined preoperatively and postoperatively (on the 1st day and 1st week) by WF SS-OCTA. The retinal thickness and microcirculation were compared before and after Nd:YAG-caps. The retinal microcirculation parameters were higher on the 1st postoperative day compared to the preoperative day, and recovered by the1st postoperative week (all p 0.05). Besides, the thickness of each retinal layer didn’t differ significantly between preoperative and postoperative measurements (all p > 0.05). There is a transient increase in retinal microcirculation after Nd:YAG-caps, and the alteration of retinal microcirculation was more sensitive than the change of thickness. WF SS-OCTA can detect such subtle change and prevent possible retinopathy in time after Nd:YAG-caps.
