AcrySof Toric人工晶状体临床应用报告及经验总结

目的:观察评价AcrySof Toric人工晶状体(IOL)矫正角膜散光的效果及在囊袋内的稳定性。方法:收集白内障并伴有角膜规则散光的患者,通过生物测量及软件计算人工晶状体型号及放置轴向,采用白内障超声乳化术植入AcrySof Toric IOL,并放置IOL于目标位置。术后随访1～3mo。观察裸眼远视力(UCDVA)、矫正远视力(BCDVA),裸眼近视力(UCNVA)及矫正近视力(BCNVA)、角膜散光、IOL旋转度,并进行分析。结果:病例1术后3mo双眼UCDVA0.3,BCDVA0.6,UC-NVA及BCNVA均为0.66。角膜散光右眼1.25D,左眼1.75D。病例2术后1mo双眼UCDVA,BCDVA,UCNVA,BCNVA均>0.6。角膜散光右眼0.75D,左眼1.00D。IOL旋转均<2°。结论:AcrySof Toric IOL能有效地矫正角膜散光,具有良好的囊袋内稳定性。

Clinical report and experience summary of AcrySof Toric intraocular lens

AIM:To evaluate the clinical effect and the rotational stability of AcrySof Toric intraocular lens(IOL).·METHODS:The type and aim-axis of IOL was calculated using calculator software.The site of incision and aim-axis of IOL was marked before operation.Phacoemulsification was performed and an AcrySof Toric IOL was implanted and rotated into astigmatic axis.Patients were followed up for 1-3 months.The uncorrected distance visual acuity(UCDVA),best corrected distance visual acuity(BCDVA),uncorrected near visual acuity(UCNVA),best corrected near visual acuity(BCNVA),corneal astigmatism,and toric lens axis were measured.·RESULTS:Case 1 after the implantation,UCDVA was 0.3,BCDVA was 0.6,UCNVA was 0.66,BCNVA was 0.66.The corneal astigmatisms were 1.25D and 1.75D.Case 2 UCDVA,BCDVA,UCNVA and BCNVA were>0.6.The corneal astigmatisms were 0.75D and 1.00D.The rotation of IOLs were within 2 degrees of right eye and left eye.·CONCLUSION:Implantation of AcrySof Toric IOL for correction corneal astigmatism is effective.This IOL showed good rotational stability in the capsular bag.
