Puesta en marcha y coordinación del Máster en Optometría Avanzada y Salud Visual

Durante el curso 2015-2016 se va a implantar, en la Universidad de Alicante, el máster en Optometría Avanzada y Salud Visual, que fue aprobado por la ANECA en diciembre del 2014. Con el fin de coordinar las actividades docentes de cada una de las asignaturas del máster y dentro del Proyecto de Redes de Investigación en Docencia Universitaria 2014-2015, se ha creado una red formada por todos los profesores coordinadores de las asignaturas que constituyen el plan de estudios y que han participado en la realización de la memoria de dicho máster. En esta red se pretende la coordinación entre todas las asignaturas para organizar y desarrollar sus actividades con el fin de conseguir una buena distribución de la carga docente y un mejor aprovechamiento por parte del alumno de la docencia recibida. Por otra parte, dado que en este máster participan varias empresas del sector óptico y clínicas oftalmológicas es necesario determinar qué actividades propuestas por las empresas y clínicas se van a incluir en cada asignatura y planificarlas adecuadamente.

Clinical Validation of Adjusted Corneal Power in Patients with Previous Myopic Lasik Surgery

Purpose. To validate clinically a new method for estimating the corneal power (P,) using a variable keratometric index (nkadj) in eyes with previous laser refractive surgery. Setting. University of Alicante and Medimar International Hospital (Oftalmar), Alicante, (Spain). Design. Retrospective case series. Methods. This retrospective study comprised 62 eyes of 62 patients that had undergone myopic LASIK surgery. An algorithm for the calculation of 11kadj was used for the estimation of the adjusted keratometric corneal power (Pkadj). This value was compared with the classical keratometric corneal power (Pk), the True Net Power (TNP), and the Gaussian corneal power (PcGauss). Likewise, Pkadj was compared with other previously described methods. Results. Differences between PcGauss and P, values obtained with all methods evaluated were statistically significant (p < 0.01). Differences between Pkadj and PcGauss were in the limit of clinical significance (p < 0.01, loA [ - 0.33,0.60] D). Differences between Pkadj and TNP were not statistically and clinically significant (p = 0.319, loA [- 0.50,0.44] D). Differences between Pkadj and previously described methods were statistically significant (p < 0.01), except with PcHaigisL (p = 0.09, loA [ - 0.37,0.29] D). Conclusion. The use of the adjusted keratometric index (nkadj) is a valid method to estimate the central corneal power in corneas with previous myopic laser refractive surgery, providing results comparable to PcHaigisL.

Positional accommodative intraocular lens power error induced by the estimation of the corneal power and the effective lens position

Purpose: To evaluate the predictability of the refractive correction achieved with a positional accommodating intraocular lenses (IOL) and to develop a potential optimization of it by minimizing the error associated with the keratometric estimation of the corneal power and by developing a predictive formula for the effective lens position (ELP). Materials and Methods: Clinical data from 25 eyes of 14 patients (age range, 52–77 years) and undergoing cataract surgery with implantation of the accommodating IOL Crystalens HD (Bausch and Lomb) were retrospectively reviewed. In all cases, the calculation of an adjusted IOL power (PIOLadj) based on Gaussian optics considering the residual refractive error was done using a variable keratometric index value (nkadj) for corneal power estimation with and without using an estimation algorithm for ELP obtained by multiple regression analysis (ELPadj). PIOLadj was compared to the real IOL power implanted (PIOLReal, calculated with the SRK-T formula) and also to the values estimated by the Haigis, HofferQ, and Holladay I formulas. Results: No statistically significant differences were found between PIOLReal and PIOLadj when ELPadj was used (P = 0.10), with a range of agreement between calculations of 1.23 D. In contrast, PIOLReal was significantly higher when compared to PIOLadj without using ELPadj and also compared to the values estimated by the other formulas. Conclusions: Predictable refractive outcomes can be obtained with the accommodating IOL Crystalens HD using a variable keratometric index for corneal power estimation and by estimating ELP with an algorithm dependent on anatomical factors and age.

Noves (i velles) didàctiques per a ensenyar llengua i literatura amb les TIC

Aquest article parteix de la hipòtesi inicial que les eines TIC presenten un gran potencial per millorar els processos d'ensenyament i aprenentatge de la llengua i la literatura, però que aquesta potencialitat (COLL: 2008) només es pot fer efectiva quan es fonamenta en una sòlida formació del professorat i quan l'ús de les TIC s'integra en metodologies actives que atorguen el protagonisme a l'estudiant i que se centren en l'acompanyament al llarg del procés, com els treballs per projectes o les seqüències didàctiques (SD) (CAMPS: 1994). Per desenvolupar aquest plantejament, primerament argumentaré la necessitat d'una formació dels docents que ha d'incloure tant la integració de les eines i dels recursos tecnològics que tenim al nostre abast, com els coneixements sobre els continguts que volem ensenyar i els coneixements pedagògics sobre com s'ensenya i com s'aprèn. I, tot seguit, em centraré en les característiques de les SD i en les possibilitats que obren per integrar els avenços que la recerca en didàctica de la llengua i de la literatura ha posat de manifest, i defensaré que són el millor marc per a un ús significatiu de les tecnologies de la informació i de la comunicació.

La literatura infantil i juvenil de Jaume Cabré

Un dels aspectes més desconeguts de la trajectòria de Jaume Cabré com a escriptor és el seu interès per la literatura infantil i juvenil. Si bé la dedicació a aquest gènere consta només de quatre obres (les novel·les Galceran, l’heroi de la guerra negra, La història que en Roc Pons no coneixia i L’home de Sau; i la nouvelle L’any del Blauet) editades entre 1978 i 1984, els textos que en resulten mostren una gran similitud, tant pel que fa al tema com a l’estructura, amb la narrativa escrita per a adults, cosa que evidencia la coherència del món literari creat per l’autor.

Seguimiento del Grado en Óptica y Optometría

En el marco del proyecto de Redes de Investigación en Docencia Universitaria 2014-15 de la Universidad de Alicante se creó, como en años anteriores, una red de trabajo formada por los profesores coordinadores de semestre y el profesor responsable de la Clínica Optométrica con el fin de realizar un seguimiento del Grado en Óptica y Optometría. Siguiendo el trabajo llevado a cabo en convocatorias anteriores, esta red de seguimiento ha prestado especial atención a la coordinación de las asignaturas de Optometría, presentes en todos los cursos, el Trabajo Fin de Grado y las Prácticas Externas. El elevado número de profesores involucrado en estas asignaturas, exige un mayor nivel de coordinación. Durante el desarrollo del curso académico se han recogido las sugerencias y propuestas realizadas a través de diferentes comisiones, así como a partir de las reuniones con el alumnado. Las comisiones que han participado son la Comisión de Grado, las comisiones de semestre y la comisión de garantía de calidad. El objetivo final ha sido optimizar el funcionamiento del título, tanto en la distribución de contenidos, como en las metodologías docentes y de evaluación de las distintas materias que componen el plan de estudios.

Experiències senzilles de física recreativa: Conservació del moment lineal, efecte Coandă i emissió atòmica

La realització pràctica d’experiments és fonamental en qualsevol disciplina científica. Per això, en aquest treball exposem una sèrie d’experiències de física senzilles i sorprenents que ens permetran reforçar diversos conceptes físics d’una manera amena, utilitzant materials molt assequibles i barats. Amb la realització d’aquests experiments volem estimular la curiositat de l’alumnat i el plaer per la investigació i el descobriment de nous fenòmens físics. Aquestes experiències estan adreçades tant a estudiants d’educació secundària i batxillerat com a alumnes dels primers cursos d’universitat. Hem dissenyat i dut a terme experiències de diversos camps de la física, entre els quals hi ha algunes pràctiques per a posar de manifest la conservació del moment lineal, o l’efecte Coandă en fluids en moviment, i també experiments de física atòmica relacionats amb l’emissió atòmica en l’espectre visible, que posen de manifest la quantització de l’energia dels nivells atòmics. Amb aquestes experiències volem motivar els alumnes en l’estudi i l’interès per la física des d’una perspectiva diferent de l’habitual.
