ABSTRACT PURPOSE: To summarize the various values of asphericity in different notations
and present how corneal asphericity, corneal curvature, and entrance pupil diameter …

As the human eye ages, the crystalline lens stiffens (presbyopia) and opacifies (cataract),
requiring its replacement with an artificial lens [intraocular lens (IOL)]. Cataract surgery is the …

This book describes the optical structure and optical properties of the human eye. For ease
of reference, the most commonly useful topics are at the beginning and topics with narrower …

Purpose.: To measure decentration following femtosecond laser small incision lenticule
extraction (SMILE) for the correction of myopia and myopic astigmatism in the early learning …

PURPOSE: To evaluate the optical and densitometric changes that take place in the
crystalline lens with aging. DESIGN: Cross-sectional study. PARTICIPANTS: Seventy-two …

OBJECTIVE: To compare the change in anterior corneal higher-order (third-to fifth-order)
aberrations (HOAs) induced by myopic and hyperopic LASIK. DESIGN: Retrospective …

The purpose of this review is to evaluate the usefulness of corneal topography to select
premium intraocular lenses (IOLs), including aspherical IOLs, toric IOLs, and multifocal IOLs …

PURPOSE: To investigate the distribution of the eye's higher-order aberrations in
postoperative laser refractive surgery patients with visual complaints and highly irregular …

The field of aberrations of the human eye is moving rapidly, being driven by the desire to
monitor and optimise vision following refractive surgery. It is important for ophthalmologists …

Purpose.: To use a large wave-front database of a clinical population to investigate
relationships between refractions and higher-order aberrations and between aberrations of …
