CFT (radius of curvature 1 mm) = central foveal thickness (microns); EDTRS (Early Treatment Diabetic Retinopathy Study): Parafoveal subfields (radius of curvature 2.22 mm): S-Para = superior parafoveal, N-Para = nasal parafoveal, I-Para = inferior parafoveal, T-Para = temporal parafoveal. Perifoveal subfields (radius of curvature 3.45 mm): S-Peri = superior perifoveal, N-Peri = nasal perifoveal, I-Peri = inferior perifoveal, T-Peri = temporal perifoveal; MT = macular thickness (average retinal thickness measurement on macular cube analysis); n = number; OCT = optical coherence tomography; TV = total volume measurement on macular cube analysis. ‘Δ’ prefix = “change in” the listed variable relative to pre-operative levels. The last row of each panel reports the p-value of the t-test of the difference between Single Peel and Double Peel; p < 0.05 was defined as statistically significant.
