Journal ArticleDOI
Standards for reporting the optical aberrations of eyes.
TL;DR: In response to a perceived need in the vision community, an OSA taskforce was formed at the 1999 topical meeting on vision science and its applications (VSIA-99) and charged with developing consensus recommendations on definitions, conventions, and standards for reporting of optical aberrations of human eyes as discussed by the authors.
Journal ArticleDOI
Scaling Zernike expansion coefficients to different pupil sizes
TL;DR: This investigation derives relationships between the Zernike expansion coefficients for two different pupil sizes by using a technique for converting Zernke expansion coefficients from one pupil size to another.
Journal ArticleDOI
Representation of videokeratoscopic height data with Zernike polynomials.
TL;DR: In this article, a methodology for decomposing corneal height data into a unique set of Zernike polynomials is presented, which can reveal the hidden height variations.
Journal ArticleDOI
