摘　　要：目的:探讨两种不同丙烯酸材料的人工晶状体应用于白内障超声乳化摘除联合玻璃体切割及人工晶状体植入术(以下简称"联合手术")治疗玻璃体视网膜疾病合并白内障的临床疗效。方法:回顾性分析联合手术治疗玻璃体视网膜疾病合并白内障患者54例55眼,C-flex组26例26眼,SA60AT组28例29眼,术后定期随访,观察视力、IOL囊袋稳定性及后发性白内障等手术并发症。结果:术后随访9～15平均(11.8±2.0)mo。最佳矫正视力:C-flex组提高20眼(77%),SA60AT组提高24眼(83%),两组间差异无统计学意义(Z=-2.97,P>0.05);人工晶状体偏心量两组间差异无统计学意义(Z=-0.01,P>0.05);预防前囊膜混浊(ACO)C-flex组优于SA60AT组(Z=-2.03,P<0.05);预防后囊膜混浊(PCO)SA60AT组优于C-flex组(Z=-2.08,P<0.05);手术主要并发症两组间差异无统计学意义(P>0.05)。结论:两种人工晶状体应用于联合手术治疗玻璃体视网膜病变合并白内障安全、有效。预防ACO,C-flex略优于SA60AT,而预防PCO,SA60AT略优于C-flex,但其作用仍待于长期观察。AIM： To evaluate the clinical outcomes of two kinds of foldable intraocular lens （IOL） with different acrylic materials in the combined phacoemulsification, pars plana vitrectomy （PPV） and intraocular lens implantation in patients with coexistent vitreoretinal disease and cataract. METHODS： A total of 54 patients （55 eyes） who had vitreoretinal disease complicated with cataract underwent the combined surgery. Their clinical data were retrospectively analyzed. Group A included 26 patients （26 eyes） with implantation of C-flex IOL and group B included 28 patients （29 eyes） with implantation of SA60AT IOL. Best corrected visual acuity （BCVA）, stability of IOL, after cataract and related complications were evaluated after the surgery. RESULTS： The follow-up period ranged from 9 to 15 months with a mean of （11. 8 ± 2. 0） months. Best corrected visual acuity （BCVA） improved in 20 eyes（77% ） in Group C-flex, and improved in 24 eyes（83%） in Group SA60AT. The difference of BCVA was not significant between two groups （Z = -2.97, P 〉 0.05）. The difference of IOL decentration between two groups was not significant （Z =-0. 01, P 〉 0. 05 ）. With respect to the prevention of anterior capsular opacity （ACO）, C-flex group was better than SA60AT group （ Z= -2.03, P 〈 0.05）, while in terms of the prevention of posterior capsular opacity （PCO）, SA60AT group was better than C-flex group （Z =-2.08, P 〈 0.05）. With regard to complications, there was no significant difference between two groups （P〉0.05）. CONCLUSION： Two kinds of IOL are feasible, safe and effective in the combined surgery for coexistent vitreoretinal disease and cataract. C-flex is slightly better than SA60AT in preventing ACO, whereas SA60AT is slightly better than C-flex in preventing PCO. The effects of preventing after cataract still need long-term observation.
