Purpose. A clinical evaluation of the Shin-Nippon NVision-K 5001 (also branded as the
Grand Seiko WR-5100K) autorefractor (Japan) was performed to examine validity and …

The aim of the thesis was to develop methods for assessment of surgically induced
astigmatism (SIA) in individual eyes, and in groups of eyes. The thesis is based on 12 peer …

Scientists and practitioners have long debated about the specific visual skills needed to
excel at hitting a pitched baseball. To advance this debate, we evaluated the relationship …

Purpose: To estimate the repeatability of refractive error measurement (REM) in a clinical
environment in cataractous, pseudophakic and healthy eyes. Methods: The refractive error …

PURPOSE: To develop methods for multivariate statistical analysis of spherocylinders and to
use these methods to compare autorefraction and manifest subjective refraction in 50 …

AIMS To assess the reliability of the hand held automated refractor Retinomax in measuring
astigmatism in non-cycloplegic conditions. To assess the accuracy of Retinomax in …

An ophthalmic method for determining a relationship between aphakic ocular power and
estimated effective lens position (ELP) of an intraocular lens (IOL) to be implanted in a …

Background: In clinical optometric practice, autorefractors are used as an objective measure
of refractive error prior to subjective refraction. We evaluate the clinical efficacy of …

Objective: The purpose of the study was to develop methods for simultaneous description of
astigmatic direction and magnitude on aggregate data, with special reference to refractive …

Myopia is a global healthcare concern and effective analyses of dioptric power are important
in evaluating potential treatments involving surgery, orthokeratology, drugs such as low …
