Abstract

We describe a case of intraoperative aberrometry-assisted (Optiwave Refractive Analysis) intraocular lens (IOL) power selection in a post-refractive surgery patient with an IOL surprise. A 46-year-old patient presented with suboptimal visual gain after phacoemulsification in the right eye. The uncorrected distance visual acuity (UDVA) in the right eye was 20/300 with residual refraction of +4.50 +1.00 × 170. She had a history of laser in situ keratomileusis in both eyes 17 years ago. She was planned for IOL exchange. No preoperative historical or lens thickness data were available, which precluded the use of established formulas. Power with conventional formulas ranged from +16.5 to +19.5 diopters (D). The previous IOL was explanted and a +20.0 D IOL was implanted in the bag after estimating power using intraoperative aberrometry. One day postoperatively, the UDVA was 20/20 with a refraction of −0.50 +0.75 × 137.

术中差测辅助人工晶状体置换在屈光术后人工晶状体意外中的应用

我们描述了一例术中像差测量辅助(Optiwave屈光分析)人工晶状体(IOL)的度数选择在屈光手术后患者与人工晶状体意外。一位46岁的患者在右眼超声乳化术后视力恢复不佳。右眼未矫正距离视力(UDVA)为20/300，残余屈光度为+4.50 +1.00 × 170。17年前，她曾做过双眼激光原位角膜磨砂手术。她计划做人工晶状体置换。没有术前历史或晶状体厚度数据，因此无法使用既定公式。常规配方的晶状体度数为+16.5 ~ +19.5 (D)。术中像差法估算晶状体度数后，取出原有的人工晶状体，植入+20.0 D的人工晶状体。术后1天UDVA为20/20，屈光度为- 0.50 +0.75 × 137。
