Purpose: To analyse whether retinal detachment (RD) after neodymium:YAG (Nd:YAG) laser posterior capsulotomy (PC) is related to a greater incidence of posterior vitreous detachment (PVD) and whether vitreous status at the time of PC is useful in predicting the risk for RD. Methods: 200 eyes of 200 patients were included in this study: 60 eyes that underwent Nd:YAG laser PC after extracapsular cataract extraction (ECCE) (G1), 60 eyes that had ECCE with IOL implantation (G2) and 80 eyes that had no surgery and were used as a control group (G3). Results: The prevalence of PVD was similar between G1 and G2 (73.4% and 70.2%, respectively) but was significantly lower in G3 (53.8%). There was no significant difference between groups in the development of PVD in eyes with attached vitreous at baseline (21%, G1; 14.2%, G2; 20.2%, G3). Conclusions: The prevalence of PVD was significantly higher in eyes after ECCE when compared to phakic eyes. Nd:YAG laser PC, was not associated with significantly higher incidence of new PVD; therefore, the presence or absence of PVD at the time of PC is not helpful in assessing the risk for RD in the first year after laser treatment.
