To compare aberration changes in pseudophakic eyes with 3 types of acrylic intraocular lenses (IOLs) and in normal phakic eyes.
Department of Ophthalmology, Asan Medical Center, Seoul, Korea.
This single-center prospective study comprised 51 cataract patients who had cataract surgery and 12 phakic eyes. Fourteen eyes received an AcrySof MA60BM (Alcon), 18 eyes received a Sensar AR40 (AMO), and 19 eyes, a Corneal ACR6D (Corneal Laboratoire). One month after cataract surgery, aberrations in the eyes were measured using a Hartmann-Shack-type aberrometer. The same measurements were done in the 12 age-matched normal phakic eyes. Individual Zernike polynomials and the root-mean-square (RMS) 3rd- and 4th-order aberrations in the 2 groups were compared. The total RMS value was also compared.
The RMS value of the 3rd- and 4th-order aberrations did not differ significantly between groups, nor did the total RMS value. In all IOL groups, an individual Zernike coefficient (C3(3), triangular astigmatism with base on the y-axis) was significantly different than that in the normal phakic group.
There was no statistically significant difference in overall higher-order aberrations between normal eyes and eyes implanted with 3 types of acrylic IOLs.
比较植入3种丙烯酸酯人工晶状体（IOL）的假晶状体眼与正常晶状体眼的像差变化。

这项单中心前瞻性研究纳入了51例接受白内障手术的患者和12只正常晶状体眼。14只眼植入了爱尔康公司的AcrySof MA60BM人工晶状体，18只眼植入了眼力健公司的Sensar AR40人工晶状体，19只眼植入了角膜实验室公司的Corneal ACR6D人工晶状体。白内障手术后1个月，使用哈特曼-夏克型像差仪测量眼内像差。对12只年龄匹配的正常晶状体眼进行同样的测量。比较两组的个体泽尼克多项式以及三阶和四阶像差的均方根（RMS）。还比较了总RMS值。
三阶和四阶像差的RMS值在各组之间无显著差异，总RMS值也无显著差异。在所有人工晶状体组中，个体泽尼克系数（C3(3)，y轴基底的三角形散光）与正常晶状体组相比有显著差异。
正常眼与植入3种丙烯酸酯人工晶状体的眼在总体高阶像差方面无统计学显著差异。
