    • A system and method is provided for integrating corneal topographic data and ocular wavefront data with primary ametropia measurements to create a soft contact lens design. Corneal topographic data is used to design a better fitting soft contact lens by achieving a contact lens back surface which is uniquely matched to a particular corneal topography, or which is an averaged shape based on the particular corneal topography. In the case of a uniquely matched contact lens back surface, the unique back surface design also corrects for the primary and higher order optical aberrations of the cornea. Additionally, ocular wavefront analysis is used to determine the total optical aberration present in the eye. The total optical aberration, less any corneal optical aberration corrected utilizing the contact lens back surface, is corrected via the contact lens front surface design. The contact lens front surface is further designed to take into account the conventional refractive prescription elements required for a particular eye. As a result, the lens produced exhibits an improved custom fit, optimal refractive error correction and vision.
    • 提供了一种系统和方法,用于将角膜地形数据和眼波前数据与原始屈光不正测量结合在一起,以创建柔软的隐形眼镜设计。 角膜地形数据用于通过实现与特定角膜形貌独特匹配的隐形眼镜后表面,或者基于特定角膜形貌的平均形状来设计更好的软性隐形眼镜。 在独特匹配的隐形眼镜后表面的情况下,独特的后表面设计也可纠正角膜的主要和高阶光学像差。 另外,眼波前分析用于确定眼睛中存在的总光学像差。 通过隐形眼镜前表面设计校正总光学像差,减少使用隐形眼镜后表面校正的任何角膜光学像差。 隐形眼镜前表面进一步被设计成考虑特定眼睛所需的常规折射处方元件。 结果,所制造的镜片表现出改进的定制配合,最佳的屈光不正的校正和视觉。
