Objective: To compare outcomes of cataract surgery combined with either anti-Vascular Endothelial Growth Factor (anti-VEGF) therapy or dexamethasone implant (DEX) in patients with diabetic macular oedema (DMO). Methods: Pubmed and Embase databases were searched for studies reporting outcomes of diabetic cataract surgery combined with either anti-VEGF or DEX, with a follow-up ≥3 months. The primary outcome was the mean change in central macular thickness (CMT). Mean change in best corrected visual acuity (BCVA) was considered as a secondary outcome. The mean difference between baseline and post-treatment values (MD) with 95%-Confidence Interval (95%CI) was calculated and meta-analyses were performed. Results: Nine-teen studies were included, 8 in the DEX group and 11 in the anti-VEGF group. A significant reduction of macular thickness was shown in the DEX group at 3 months (MD = −98.35 µm; 95% CI, −147.15/−49.54), while mean CMT change was non-significant in the anti-VEGF group (MD = −21.61 µm; 95% CI, −59.46/16.24; test of group differences, P < 0.001). At 3 months, no difference in visual gain was found between the two groups (P = 0.13). Conclusions: In DMO patients, cataract surgery combined with DEX seems to provide better anatomical outcomes compared with cataract surgery combined with anti-VEGF therapy. However, our evidence was limited by significant heterogeneity. Randomised trials comparing these two different combined approaches are warranted.
