The PARK 1 ® combines a non-contact pachymeter, auto-refractometer and keratometer in one unit. In addition to the objective refraction, the keratometer values and the pachymetry can be determined ...

May 4, 2017 - Even objective, automated vision testing--using a device called an autorefractor--gives variable results in patients with Down syndrome, reports a study in the May issue of Optometry and ...

A comparative study was conducted from August 2005 to May 2008, at Hospital Universiti Sains Malaysia and Hospital Raja Perempuan Zainab II, Kelantan, Malaysia. The sample size was calculated using ...

The applications of wavefront technology in eye care extend beyond custom ablation. When used purely for diagnostics, wavefront can surpass traditional methods of refraction, measuring higher-order ...

Objective screening requires less input from children and is faster. With objective screening, the child merely needs to focus on a device long enough to obtain a measurement. One of the most basic ...

The aim of this study was to present methods to improve the analysis of refractive data. A comparison of methods is used to analyse refractive powers using individual powers and aggregate data.

Even objective, automated vision testing—using a device called an autorefractor—gives variable results in patients with Down syndrome, reports a new study. Even objective, automated vision testing -- ...
