PURPOSE: To evaluate the changes in the optical quality of corneas of hyperopic patients operated using central multifocal presbyLASIK treatment through the study of light patterns around the retinal plane.
METHODS: This study included eight hyperopic eyes that underwent central…

An analytical approximate procedure for a class of conservative single degree-of-freedom nonlinear oscillators with odd non-linearity is proposed. This technique is based on the generalized harmonic balance method in which analytical approximate solutions have rational forms. Unlike the classical harmonic…

The analytical approximate technique developed by Wu et al for conservative oscillators with odd nonlinearity is used to construct approximate frequency-amplitude relations and periodic solutions to the dynamically shifted oscillator. This nonlinear oscillator is described by an equation of motion…

3,3'-Bis(dialkylaminomethyl)-1,1'-binaphth-2-ols (Binolams) have emerged during the last five years as very efficient chiral ligands in many enantioselective processes. Enantiomerically pure Binolams are easily accessible by means of a variety of methods, the most widely used being the so-called chiral Binol…

Information Systems (IS) outsourcing is a growing phenomenon in present-day firms that has generally been characterised with an insufficient level of detail and analysis. This is mainly due to the fact that outsourcing has been studied as a set of…

To analyze the present status of rheumatological research in Spain, three indicators have been evaluated: use of the difference study designs, use of statistical techniques and relevance of the studies. This last point was determined by the comparison of the…

In this communication, we report a new method to determine the wavefront
aberration function of personalized eyes. We obtain corneal surface data and
axial lengths for different eyes. With these data, we construct a diffractive model
of a human eye,…

PURPOSE: To compare the visual results of presbyLASIK patients to the best theoretical pseudoaccommodation that could be achieved using a multifocal refractive intraocular lens (IOL) model based on the optical
structure of a simulated AMO Array multifocal IOL.
METHODS: The…

Despite increased numbers of female researchers, women still face more difficulties than their male counterparts when it comes to publishing their work and having it read and cited. In this editorial, the main recommendations are detailed in order to promote…
