摘　　要：目的观察和探讨高度近视并发性白内障患者行超声乳化吸除联合Bigbag人工晶状体植入术后的早期临床效果。方法研究组18例(30眼),行白内障超声乳化吸除联合Bigbag人工晶状体植入术;对照组17例(28眼),行白内障超声乳化吸除联合Rayner人工晶状体植入术。观察患者术后第1个月的最佳矫正视力(best corrected visual acuity,BCVA)、术后第1个月与术前中轴区晶状体后囊膜到视网膜间距离的差值、术后并发症等指标。结果术后第1个月,研究组BCVA<4.5者3眼,4.5～4.7者10眼,≥4.8者17眼,与对照组相比,差异无统计学意义。术后第1个月与术前中轴区晶状体后囊膜到视网膜间距离的差值,研究组为(1.49±0.03)mm,对照组为(1.93±0.06)mm,两组间差异有统计学意义(P<0.05),研究组的变化值小于对照组。术后未见严重并发症。结论Bigbag人工晶状体不但可获得与其他人工晶状体相同的良好术后视力,同时由于其设计上的特殊性,对术后后囊膜起到稳定的支撑作用,减弱因人工晶状体植入对眼球内部环境的影响。Objective To investigate the early effects of pha- coemulsification and Bigbag intraocular lens （IOL） implantation on patients with high myopia and cataract. Methods Eighteen patients （30 eyes） underwent phacoemulsification and Bigbag IOL implanta- tion （test group）. Seventeen patients （28 eyes） underwent pha- coemulsification and Rayner IOL implantation （control group）. Best corrected visual acuity （BCVA） and variations in the distance from the posterior capsule membrane to the retina were measured before surgery and 1 month after surgery, and postoperative complications were observed. Results One month after surgery, the BCVA of 3 eyes were below 4.5 in the test group, 10 eyes were between 4.5 and 4.7, and 17 eyes were above 4.8, which was no different from the control group. The variations in distance from the posterior cap- sule membrane to the retina were significantly different between the test group [（1.49＋0.03）mm] and the control group [（1.93＋0.06）mm]. Variation in the test group was less than that of the control group （P〈0.05）. Conclusion Bigbag IOL implants, like other IOL im- plants, not only helps the patients obtain good distance acuity after cataract surgery, but also functions to support the posterior capsule membrane because of its special design. It is effective and safe, and should reduce the risk of retinal detachment for those with high myopia.
