A generalization of the Prentice's law is presented in this paper. The idea consists of removing some (but not all) of the approximations that comprise the paraxial approach. In that way, we obtain a new formulation that permits us to compute the prismatic power of a lens made up of arbitrary refracting surfaces, and to improve the precision obtained by Prentice's law when applied to monofocal lenses. The resulting formalism is simple and manageable and its derivation leads us to a precise definition of the local dioptric power matrix, introduced in a previous paper, as well as a better understanding of the same.
本文提出了普伦蒂斯定律的一种推广。其思路是去除构成傍轴近似的一些（但不是全部）近似。通过这种方式，我们得到了一种新的公式，它使我们能够计算由任意折射面组成的透镜的棱镜度，并提高普伦蒂斯定律应用于单焦点透镜时所获得的精度。所得的形式体系简单且易于处理，其推导使我们得到了前一篇论文中引入的局部屈光力矩阵的精确定义，以及对其更好的理解。
