Optical Quality in Eyes Implanted With Aspheric and Spherical Intraocular Lenses Assessed by NIDEK OPD-Scan: A Randomized, Bilateral, Clinical Trial
(SLACK INC, 2011)
PURPOSE: To determine whether implantation of an intraocular lens (IOL) with an aspheric surface (Akreos AO, Bausch & Lomb Inc) results in reduced ocular aberrations (spherical aberration) and improved Strehl ratio and ...
Helicobacter pylori and Iron-deficiency Anemia in Adolescents in Brazil
(LIPPINCOTT WILLIAMS & WILKINS, 2010)
Aim: The aim of the study was to evaluate the association between Helicobacter pylori infection and iron deficiency (ID) in adolescents attending a public school. Patients and Methods: From March to June 2001, a cross-sectional ...
C-13-urea breath test with infrared spectroscopy for diagnosing Helicobacter pylori infection in children and adolescents
(Lippincott Williams & Wilkins, 2002-07-01)
Background and Objective: Studies support the accuracy of C-13-urea breath test for diagnosing and confirming cure of Helicobacter pylori infection in children. Three methods are used to assess (CO2)-C-13 increment in ...
Modulation transfer function and optical quality after bilateral implantation of a+3.00 D versus a+4.00 D multifocal intraocular lens
(ELSEVIER SCIENCE INCNEW YORK, 2012-02)
PURPOSE: To determine whether the improvement in intermediate vision after bilateral implantation of an aspheric multifocal intraocular lens (IOL) with a +3.00 diopter (D) addition (add) occurs at the expense of optical ...

Optical quality of foldable monofocal intraocular lenses before and after injection. Comparative evaluation using a double-pass system
(Elsevier Science Inc, 2009-08)
Purpose: To use the double-pass technique to evaluate the in vitro optical quality of foldable monofocal intraocular lenses (IOLs) used to correct aphakia. Setting: Universitat Politècnica de Catalunya, Terrassa, and ...
The Lévy fractional Brownian motion family as a new paradigm in the modeling of turbulent wave-front phase
(Society of Photo-Optical Instrumentation Engineers, 2007-09-25)
In Perez et al. [J. Opt. Soc. Am. A 21 (10), 2004] we have given a general formalism to model the turbulent wave-front phase by using fractional Brownian motion processes. Moreover, it extends classical results to non- ...
