To expand upon and clinically demonstrate the results of a new polynomial decomposition method.
To discuss the theoretical considerations comparing the qualitative and quantitative information produced by the Zernike coefficients and a new polynomial decomposition basis, in a comparative series of theoretical and clinical case studies.
These comparative studies validate the novel polynomial basis that decomposes the wavefront, with clear segregation of the higher and lower aberrations. There is no artifactual reduction of some of the higher order aberration coefficients, providing a more clinically relevant retinal image quality prediction.
Some of the inherent limitations of the Zernike polynomials in clinical ophthalmic applications can be solved by a novel set of polynomials forming an alternative higher order basis. The new basis provides a clear separation between modes containing lower order terms versus higher order terms and offers clinicians a more clinically realistic wavefront analysis.

扩展和临床展示一种新的多项式分解方法的结果。
通过一系列理论和临床病例研究，讨论比较 Zernike 系数和新的多项式分解基产生的定性和定量信息的理论考虑。
这些比较研究验证了新的多项式基，它分解了波前，清楚地区分了高低阶像差。没有对某些高阶像差系数进行人为的降低，从而提供了更具临床相关性的视网膜图像质量预测。
通过一组形成替代高阶基的新多项式，可以解决 Zernike 多项式在临床眼科应用中的一些固有局限性。新的基在包含低阶项和高阶项的模式之间提供了清晰的分离，并为临床医生提供了更具临床现实意义的波前分析。[J Refract Surg. 2020;36(2):74-81.]。
