CME = cystoid macular edema; ERM = persistent/recurrent epiretinal membrane; IRC = inner retinal cysts; IRD = inner retinal dimpling; n = number; OCT = optical coherence tomography; POM = postoperative month. The last column reports the p-value of the Fisher exact test of the difference between Single Peel and Double Peel;
