Phacoemulsification and intraocular lens implantation combined vitrectomy(phacovitrectomy)cannot only correct refractive error but also treat vitreoretinal diseases. Due to its advantages of clearer intraoperative vision, postoperative visual function improvement and avoiding secondary procedures, phacovitrectomy has been increasingly used in patients with retinal and vitreous diseases combined with cataracts. Compared with traditional staged surgery, phacovitrectomy require special equipment and is higher technique-demanding and more complications. Several studies have shown that refractive error is commonly reported after surgery. In this article, the relevant influencing factors, formation mechanism and updated control strategy of RE were summarized to provide reference for the indication selection, avoidance of complications and more satisfactory postoperative visual function.
