Title

"On the measurement of higher order optical aberrations"

Abstract

It is envisaged that highly advanced customized surgical procedures will dominate vision correction in the next decade. The future goal of refractive surgery is to achieve 20/10 uncorrected visual acuity with aberration-free postoperative vision. It is predicted that these advanced customized refractive surgeries will correct many of the aberrations of the eye, providing vision levels limited only by the resolution of the retinal photoreceptors and the diffraction due to the pupil's aperture. However, the clinical outcomes of modern surgical procedures depend to a great extent on advances in eye measurement systems. They include systems for accurate measurement of the anterior and posterior corneal surfaces as well as for measurement of total aberrations of the eye. It is essential that the data provided by the eye measurement systems are well understood. In this talk we provide some insight into how information from the eye measurement systems could be efficiently used. The precision and accuracy of current instruments will be reviewed. Corneal and total aberrations of the eye as well as the dynamics of ocular aberrations will be discussed.
