For vitreous opacity (VO) patients, the BCVA improvement in group A (0.34± 0.51) was significantly better than that in group B (0.15± 0.52, P=0.03), with a shorter surgical time (45.22± 8.15 vs 52.72± 7.17 min, P < 0.0001) and lower complication rate (7.14% vs 11.68%). Overall, group A had a shorter surgical time (47.75± 10.06 vs 59.22± 11.6 min, P < 0.0001) and better postoperative BCVA (0.36± 0.45 vs 0.49± 0.48, P=0.0001) than group B, but higher surgical costs (21,600± 9180 vs 15,399± 2996 yuan, P < 0.0001).Conclusion: FLACS+PPV has excellent therapeutic effects but is expensive, while CPS+PPV has a high cost-effectiveness, and clinical selection should be based on the patient’s condition.Keywords: femtosecond laser-assisted cataract surgery, conventional phacoemulsification surgery, pars plana vitrectomy, fundus diseases, cataract
