目的：探究玻璃体切除术同期联合白内障超声乳化吸除术对PDR患者视力、眼压、CMT及术后并发症的影响。

方法：将2015-02/2017-02我院收治的PDR患者90例98眼根据自愿原则分为：A组(玻璃体切除术同期联合晶状体切除术，45例50眼)，B组(玻璃体切除术同期联合白内障超声乳化吸除术，45例48眼)。术后随访6mo，比较两组视力改善情况、手术前后眼压、CMT及术后并发症发生率。

结果：术后B组视力改善情况显著优于A组，视力提高率显著高于A组(P<0.05)； 两组术前、术后眼压均无差异(P>0.05)； 术后两组CMT均有显著降低，两组CMT无差异(P>0.05)； B组INV、囊膜混浊、角膜水肿、瞳孔挟持、硬性渗出术后并发症发生率均显著低于A组(P<0.05)。

结论：玻璃体切除术同期联合白内障超声乳化吸除术治疗PDR疗效明显，可促进患者术后视力恢复，降低CMT，且并发症风险较低。

METHODS:Totally 90 PDR patients(98 eyes)admitted to the hospital from February 2015 to February 2017 were divided into two groups according to the principle of voluntariness: group A(vitectomy simultaneously combined with lensectomy, 45 cases, 50 eyes)and group B(vitrectomy simultaneously combined with phacoemulsification, 45 cases, 48 eyes). The follow-up period was 6mo. The visual acuity improvement, IOP before and after surgery, CMT and incidence of postoperative complications were compared between the two groups.

RESULTS: The visual acuity improvement after surgery in group B was significantly better than that in group A, and the improving rate of visual acuity was significantly higher than that in group A(P<0.05). There was no significant difference in IOP before and after surgery between the two groups(P>0.05). The CMT after surgery was decreased significantly in both groups. CMT in both groups was not statistically different(P>0.05). The incidence rates of postoperative complication ssuch as INV, capsule turbidity, corneal edema, pupil hijacking and hard exudate in group B were significantly lower than those in group A(P<0.05).

CONCLUSION:Vitrectomy simultaneously combined with phacoemulsification have obvious efficacy on PDR, which promote recovery of postoperative visual acuity, reduce CMT, and it has low risk of postoperative complications.
