Cataract combined with retinopathy can seriously affect the vision of patients. Vitrectomy combined with one-stage implantation of multi-focal intraocular lens (MIOL) has been paid more and more attention. The application of MIOL shows potential in improving the visual quality of patients, but its effect is affected by many factors, and refractive drift is a key problem to be solved. At present, the research mainly focuses on cataract patients with high myopia, and further research on other types of retinopathy is needed. In the future, multi-center, large-sample, long-term clinical studies and interdisciplinary cooperation are needed to optimize surgical and management programs to enhance the application effect of MIOL in the treatment of retinopathy and improve the quality of life of patients.
