目的：通过波前像差光路系统探讨人工晶状体(IOL)偏心和倾斜对光学成像质量的影响。

方法：在5.0mm模拟瞳孔直径下，采用实验室搭建的Hartmann-Shack IOL波前像差光路系统检测球面IOL Sensar AR40e、非球面单焦点IOL Tecnis ZA9003、非球面多焦点 IOL Tecnis ZM900分别在偏中心0、0.2、0.4、0.6、0.8mm，向鼻侧和颞侧倾斜5°、10°、15°、20°、25°时对光学成像质量的影响，以高阶像差和调制传递函数(MTF)定量成像质量。

结果：倾斜5°以内时，Tecnis ZA9003 MTF值高于AR40e和Tecnis ZM900，而倾斜5°、10°、15°、20°时三种IOL MTF值有显著差异。Tecnis ZA9003 IOL倾斜角度与彗差呈显著正相关(r=0.842，P<0.001)，与球面像差无显著相关性(r=0.229，P=0.241)。偏心0.6、0.8mm时三种IOL MTF值有显著差异(均P<0.001)，Tecnis ZM900偏心大于0.4mm时成像质量明显下降。

结论：具有-0.27μm球差的非球面IOL倾斜度小于5°，偏心小于0.4mm时可获得比球面IOL更好的光学成像质量。Tecnis ZM900 IOL偏心大于0.4mm时较球面和非球面IOL的光学成像质量降低。

METHODS: The spherical IOL Sensar AR40e, the aspherical monofocal IOL Tecnis ZA9003, and the aspheric multifocal IOL Tecnis ZM900 were measured at the center of the center using a laboratory-built Hartmann-Shack IOL wavefront aberration path system at 5.0mm simulated pupil diameter. 0, 0.2, 0.4, 0.6, 0.8mm, the effect on the optical imaging quality when tilting 5°, 10°, 15°, 20°, 25° to the nasal side and the temporal side, and quantitative imaging quality by high-order aberration and modulation transfer function.

RESULTS: The Temnis ZA9003 MTF value was higher than AR40e and Tecnis ZM900 when inclinationed within 5°, while the three IOL MTF values were significantly different when inclinationed 5°, 10°, 15°, and 20°. Tecnis ZA9003 The IOL inclination angle was significantly positively correlated with the coma(r=0.842, P<0.001), and there was no significant correlation with the spherical aberration(r=0.229, P=0.241). The three IOL MTF values were obtained when the eccentricity was 0.6 and 0.8 mm. Significant differences(both P<0.001), the imaging quality of the Tecnis ZM900 eccentricity greater than 0.4mm decreased significantly.

CONCLUSION: When the inclination of aspheric IOL(-0.27μm spherical aberration)is less than 5°and the eccentricity is less than 0.4mm, aspherical IOL has a better imaging quality than that of spherical IOL. Tecnis ZM900 IOL has a lower optical imaging quality than that of spherical and aspheric IOL when the eccentricity of IOL is more than 0.4mm.
