研究了聚甲基丙烯酸甲酯人工晶状体形状对人工晶状体眼光学性能的影响。图像质量标准包括波像差、点图、纵向像差、调制传递函数和优化程序。对于大多数人患有角膜非球面的眼睛来说,轴上视力的最佳镜片形状接近平凸,其中更弯曲的表面面向角膜。无论镜头是否正确居中、倾斜或偏心,这都适用。对于小离轴角,最佳透镜形状随目镜参数而变化。良好的人工晶状体形状范围从平凸到等凸。不推荐曲面朝向视网膜的平凸镜片。
The effect of poly(methyl methacrylate) intraocular lens shape on optical performance of pseudophakic eyes was investigated. Image quality criteria included wave aberrations, spot diagrams, longitudinal aberrations, the modulation transfer function, and an optimization procedure. For eyes with corneal asphericities encompassing most of the population, the optimum lens form for on-axis vision is close to plano-convex, with the more curved surface facing the cornea. This applies whether lenses are correctly centered, tilted, or decentered. For small off-axis angles, optimum lens shape varies with the ocular parameters. Good intraocular lens shapes range from the plano-convex to the equi-convex. Plano-convex lenses with the curved surface facing the retina are not recommended.
