Clinical use of the ocular point spread function for retinal image quality assessment
The purpose of this study is to demonstrate the clinical use of the point spread function (PSF) as metric for the assessment of retinal image quality in eyes with different ocular conditions. The PSF was computed from the wavefront aberrations obtained in seven eyes with different ocular conditions: emmetropia, myopia, hyperopia, post-myopic laser in situ keratomileusis (LASIK), post-hyperopic LASIK, keratoconus, Intacs ® in keratoconus, radial keratotomy (RK), LASIK after RK, cataract, phacoemulsification after cataract surgery, and LASIK after astigmatic keratotomy. The Strehl intensity ratio was calculated for all the PSFs computed. The PSF was correlated with the change in the optical e…
Visual acuity comparison of 2 models of bifocal aspheric intraocular lenses.
Purpose To compare visual acuity after bilateral implantation of 2 models of multifocal aspheric intraocular lenses (IOLs). Setting Fernandez-Vega Ophthalmological Institute, Oviedo, and University of Valencia, Valencia, Spain. Methods Prospective study of patients who had bilateral implantation of an AcrySof ReSTOR SN6AD3 IOL (Group 1) or an Acri.LISA 366D IOL (Group 2). Six months postoperatively, binocular uncorrected and best corrected distance visual acuity, uncorrected-distance and best distance-corrected near visual acuity, best corrected intermediate visual acuity, and the defocus curve were measured in both IOL groups. Results Group 1 comprised 36 eyes (18 patients) and Group 2, 40…
Intermediate visual function with different multifocal intraocular lens models
Purpose To compare visual acuity at different distances after bilateral implantation of 1 of 4 multifocal intraocular lenses (IOLs). Setting Fernandez-Vega Ophthalmological Institute, Oviedo, Spain. Methods This study evaluated consecutive patients who had bilateral implantation of a spherical multifocal IOL with a +4.00 diopter (D) addition (add) (AcrySof ReSTOR SN60D3) or an aspheric multifocal IOL with a +4.00 D add (AcrySof ReSTOR SN6AD3), +3.75 D add (Acri.LISA 366D), or +3.00 D add (AcrySof ReSTOR SN6AD1). Six months postoperatively, binocular measurement of corrected distance visual acuity (CDVA) at 4 m, corrected near visual acuity (CNVA) at 40 cm, and corrected intermediate visual …
Atención a los Objetivos de Desarrollo Sostenible (ODS) en el Área de Ciencias de la Naturaleza de Educación Primaria
Desde las últimas décadas del siglo XX, se han realizado numerosos llamamientos a los docentes, de todas las áreas y niveles, para que la educación preste atención a la preparación de la ciudadanía para hacer frente a la situación de crisis planetaria. En ese marco, con el fin de contribuir a la educación ciudadana, este estudio se centra en analizar, en particular, la atención en el área de Ciencias de la Naturaleza de Educación Primaria a los Objetivos de Desarrollo Sostenible (ODS), aprobados por Naciones Unidas en 2015. Para ello se aborda el estudio del currículo de Primaria de Ciencias de la Naturaleza y el contenido de libros de texto de dicha área, así como las concepciones docentes…
