超高度近视白内障超声乳化联合Bigbag晶状体植入疗效观察

目的探讨超高度近视合并白内障行超声乳化吸出联合Bigbag人工晶状体植入术的临床疗效。方法表麻下对25例（30眼）超高度近视合并自内障行超声乳化吸出联合Bi曲ag人工晶状体植入术。术后观察玻璃体的活动度、最佳矫正视力、屈光度和手术并发症。随访1—8个月。结果术后最佳矫正视力≥0．5者共8眼（26．7％），0．3—0．4者共16眼（53．3％），〈0．3者6眼（20％）。术中无晶状体后囊破裂。常见情况为术后1d角膜不同程度水肿，在3—10d内自行消退。术后无视网膜及脉络膜脱离，无黄斑囊样水肿或后发障等并发症。结论超声乳化联合Bigb职人工晶状体植人术治疗超高度近视自内障能有效改善视力，增加玻璃体的稳定性，有效降低并发症的发生。

The efficacy of phacoemulsification and aspiration combined with Bigbag IOL implantation for superhigh myopia with cataract

Objective To study the clinical effects of phacoemulsification and aspiration combined with Bigbag intraocular lens implantation for superhigh myopia with cataract.Methods Twenty-five cases (30 eyes) of superhigh myopia with cataract were treated by phacoemulsification combined with Bigbag intraocular lens implantation under surface anesthesia.Flexibility of vitreous body,best corrected visual acuity ( BCVA),refraction diopter and complications were observed after surgery.The follow-up period was 1 to 8 months.Results For the BCVA,8 eyes were ≥0.5(26.7％ ),16 eyes were 0.3 ～0.4(53.3％ ),and 6 eyes were ＜ 0.3 (20.0％),respectively.No posterior capsular rupture was detected during the surgery.Corneal edema of various degrees showed on day 1 after surgery,and eliminated 3 to 10 days later.No retinal detachment,choroids detachment,cystoid macular edema and after-cataract were noted.Conclusion Phacoemulsification combined with Bigbag intrancular lens implantation could improve the visual acuity of patients with superhigh myopia with cataract,enhance the stability of vitreous body and prevent the occurrence of complications.
