Primary acrysof foldable intraocular lens implantation of posterior capsules and zonules rupture with senile cataracta extracted by phacoemulsification

目的 评价Acrysof折叠式人工晶体在白内障超声乳化术中后囊膜破裂时Ⅰ期植入的方法和疗效。方法 10 2 6眼老年性白内障超声乳化术中后囊膜破损 3 8眼 ,悬韧带断离 8眼 ,共 46眼。 2 7眼经 3 .2～ 4.0mm切口Ⅰ期植入Acrysof折叠式人工晶体 ,15眼经 5 5～ 6.0mm切口Ⅰ期植入PMMA人工晶体。结果 植入Acrysof者术后视力≥ 0 5者术后 3天 ,1周 ,1月分别为 70 % ,85 % ,96% ;植入PMMA者则分别为 3 3 % ,73 % ,80 %。植入Acrysof者优于植入PMMA者 ,P<0 .0 1,0 0 5 ,0 0 5。主要并发症总和发生率Acrysof组低于PMMA组 ,P <0 .0 5。所有人工晶体光学中心均位于瞳孔区。结论 后囊膜破裂时尽可能行小切口Ⅰ期植入Acrysof折叠式人工晶体 。

Objective To investigate the effectiveness and technique of primary acyrsof foldable intraocular lens implantation of posterior capsules and zonules rupture with senile cataracta by phacoemulsification.Methods 1026 senile cataract eyes had undergone phacoemulsication the acrysof foldable intraocular lens was implanted primarily through a 3.5～4.0mm cornea tunnel incision in 27 eyes and the PMMA rigid intraocular lens was implanted in 15 eyes through a 5.5～6.0mm cornea-scleral tunnel incision in 15 eyes with capsule and zonules rupture.Results 70%,85% and 96% of the acrysof group and 33%,73% and 80% of the PMMA group achieved a visual acuity equal to 0.5 or better at 3rd day,1week and 1 month after the operation respectively.There was statistical difference between them( P <0.01,0.05,0.05).The main complication ratios were 33% in the acrysof group and 60% in the PMMA group.There was statistical difference between them( P <0.05).The position of all IOL was in the optical center.Conclusion The acrysof foldable intraocular lens implantation of capsule and zonules rupture is more effective than the PMMA intraocular lens implantation.
