Purpose: To validate the proposed optical requirements of a draft international standard for
intraocular lenses (IOLs). Setting: Eight optical testing laboratories in the United States, …

Purpose: To describe a testing program conducted by a standards group as a guide for setting
international tolerances for intraocular lens (IOL) dioptric power. Setting: Multicenter study…

The purpose of this study was first to evaluate the clot capture efficiency and capture
location of six currently-marketed vena cava filters in a physiological venous flow loop, using …

MATERIALS AND METHODS Tc-99m DMPE. The preparation and chemistry of this agent
have been detailed in a recent report from our

Methods The participants jointly developed and followed a limited test protocol based on
accepted methods outlined in the International Standards Organization 5840: Cardiovascular …

In the 1994 Replacement Heart Valve Guidance of the US Food and Drug Administration (FDA),
in-vitro testing is required to evaluate the potential for cavitation damage of a …

A basic goal associated with the manufacture of intraocular lenses (IOLs) is that they not be
vision limiting. Manufacturers must therefore test IOL resolution against some minimum …

We investigated the use of modulation transfer function (MTF) measurements to provide a
standard test of minimum optical quality of intraocular lenses. We used a water cell with plane …

Intraocular lenses (IOLs) from 15 US firms were tested for conformance to the requirements
of the American National Standards Institute Z80. 7 standard for IOLs. A total of 162 IOLs …

The optical quality of 81 monofocal poly(methyl methacrylate) intraocular lenses (IOLs) from
eight US firms was tested using a 3 mm aperture, as recommended by the American …
