Study: Visual outcomes and incidence of pseudophakic cystoid
A Study was conducted to determine whether pars plana vitrectomy (PPV) or cataract surgery should be performed first in concurrent epiretinal membrane (ERM) and cataract treatment with respect to visual outcome and pseudophakic cystoid macular oedema (PCMO) incidence.

Patients who underwent PPV and cataract surgery sequentially at a tertiary medical centre were retrospectively recruited. Best-corrected visual acuity (BCVA) and central macular thickness (CMT) measured from optical coherence tomography (OCT) images collected before and after each surgery were documented. OCT-defined PCMO incidence and its influence on visual outcomes were analysed.

Results:
--In total, 259 and 159 eyes received PPV before and after cataract surgery, respectively.

--The ERM-CATA group had better final BCVA and greater BCVA gain than did the CATA-ERM group.

--Baseline BCVA was positively correlated with final BCVA, whereas baseline CMT, final CMT, and postoperative CMT changes were not. PCMO incidence did not differ significantly between the two groups (15.4% vs. 19.5%), and final BCVA changes did not significantly differ between eyes with and without PCMO.

--PCMO incidence was much higher (29.40% vs. 16.30%) in eyes with baseline CMT more than 500 microm.

PPV should also be done before cataract surgery in order to produce superior visual results for the management of ERM and cataract. Both operating sequences produce equivalent rates of PCMO. Greater CMT baseline is a PCMO risk factor after cataract surgery.
