Bifocal and multifocal optical devices are intended to get images into focus from objects
placed at different distances from the observer. Spectacles, contact lenses, and intraocular …

One of the most powerful clinical applications of aberrometry is wavefront‐guided refractive
surgery. This concept led to a paradigm shift in refractive error correction, and the same …

ABSTRACT PURPOSE: To compare experimental optical performance in eyes implanted
with spherical and aspheric intraocular lenses (IOLs). METHODS: Corneal, total, and …

Corneal and ocular aberrations were measured in a group of eyes before and after cataract
surgery with spherical intraocular lens (IOL) implantation by use of well-tested techniques …

purpose. To measure the magnitude and orientation of the Zernike terms in keratoconic
eyes, with and without rigid gas-permeable (RGP) contact lenses. methods. A total of 76 …

Purpose To investigate the feasibility of correcting ocular higher order aberrations (HOAs) in
keratoconus (KC) using wavefront-guided optics in a scleral lens prosthetic device (SLPD) …

Keratoconus (KC) is a progressive disease that leads to major losses of visual quality and
related quality of life. Contact lens (CL) application has a primary place and importance in …

Handbook of Visual Optics offers an authoritative overview of encyclopedic knowledge in the
field of physiological optics. It builds from fundamental concepts to the science and …

We present a Purkinje imaging system for phakometry and measurement of tilt and
decentration of crystalline and intraocular lenses (IOLs). Crystalline lens radii of curvature …

After outlining what is meant by wavefront aberration, the history of the field of wavefront
technology is sketched and methods for measuring ocular wavefront aberration are briefly …
