Objective To evaluate the clinical effects of Bigbag intraocular lens implanted in high myopia eyes complicated by cataract after phacoemulsification .Methods Twenty-five high myopia patients (38 eyes) with cataract received phacoemulsification to remove cataract .Then the Bigbag intraocular lens were implanted into capsular bags.The intraoperative and postoperative complications were observed .The indices including visual acuity ,refractive status,position of the intraocular lens,morphology of the posterior capsule and the retina were evaluated preoperatively and postoperatively.Results Uncorrected distant visual acuity ( UCDVA) and best corrected distant visual acuity (BCDVA) detected 1 week and 6 months after operation significantly improved compared with the preoperative ones (P<0.05).UCDVA and BCDVA detected 1 week after operation were not significantly different from those detected 6 months after operation(P>0.05).Six months after operation,the spherical diopter decreased significantly compared with the preoperative one(P<0.05),the D-value of postoperative actual refraction and target refraction≤±1.0D.All intraocular lens were in the central of capsular bags .No posterior capsular wrinkle,retinal detachment and macular edema were observed,and the incidence of posterior capsule opacification (PCO) was 5.26%.Conclusion Bigbag intraocular lens implantation is safe and effective for high myopia patients with cataract who accept phacoemulsification .% 目的评估Bigbag人工晶状体应用于高度近视并发白内障超声乳化术的临床效果。方法25例（38眼）高度近视并发白内障患者接受白内障超声乳化吸除联合Bigbag人工晶状体植入术，观察术中、术后并发症，评价术前术后视力、屈光状态、人工晶状体位置、晶状体后囊膜形态、眼底改变等指标。结果术后1周、术后6个月裸眼远视力及最佳矫正远视力均优于术前（P＜0．05），但术后1周、术后6个月裸眼远视力及最佳矫正远视力比较，差异无统计学意义（P＞0．05）；术后6个月屈光度明显低于术前（P＜0．05），实际屈光度与预留度数偏差值≤±1．0D，人工晶状体位置居中稳定，后嚢膜无皱褶，未发生视网膜脱离及黄斑水肿，后发性白内障发生率为5．26％。结论白内障超声乳化联合Bigbag人工晶状体植入术治疗高度近视并发白内障安全、有效。
