There is renewed interest in the role of optics in human vision. At the same time there have
been advances that allow for routine standardized measurement of the wavefront …

Background: Given the lack of standardization in stimulus types for assessing
accommodation, we aimed to evaluate accommodative response (AR) and Zernike …

Context: The acute effects of cigarette smoking on pupil size and ocular wavefront
aberrations (OWA) have been previously documented. The accommodation status of the eye …

Advancements in clinical measurement of refractive errors should lead to faster and more
reliable measurements of such errors. The study investigated different aspects of …

Galileo's contemporary, Christophoro Scheiner, explored the nature of eyes as optical
instruments and discovered how to measure the eye's focusing distance simply by viewing a …

Background Many patients voice concerns regarding poor night vision, even when they see
20/20 or better in the exam room. During mesopic and scotopic conditions the pupil size …

El queratocono es un desorden, generalmente bilateral y asimétrico que cursa con un
adelgazamiento progresivo del espesor del estroma central y/o paracentral corneal y una …

Background Many patients voice concerns regarding poor night vision, even when they see
20/20 or better in the exam room. During mesopic and scotopic conditions the pupil size …

Purpose. To investigate the reliability of ocular aberration measurement in myopic children
under scotopic conditions and to validate the mathematical Zernike pupil scaling‐down …

Objetivo: es estudiar la fiabilidad de la refracción automática que proporciona el
aberrómetro i. Profilerplus (Carl Zeiss, Germany) comparado con el autorrefractometro …
