    The inscription of diffractive elements in ophthalmic polymers and ocular tissues to induce refractive index changes is of great interest in the fields of Optics and Ophthalmology. In this work fabrication of linear periodic patterns in polydimethylsiloxane (PDMS) intraocular lenses by means of the direct laser interference patterning (DLIP) technique was studied. A Q-Switch Nd:YAG laser coupled to second and third harmonic modules emitting linearly polarized 4 ns pulses at 355 nm with 20 Hz repetition rate was used as the laser source. Laser processing parameters were modified to produce the linear patterns. Processed samples were characterized by means of optical confocal microscopy, Scanning Electron Microscopy SEM, Energy Dispersive X-ray Spectroscopy EDX, Attenuated Total Reflectance-Infrared Spectroscopy ATR-FTIR, and Raman Spectroscopy. Depending on the laser parameters both photo-thermal and photo-chemical damage were observed in the DLIP irradiated areas. Finally, diffractive techniques were used to characterize the diffraction gratings inscribed in the samples resulting in a refractive index change of 1.9 × 10−2 under illumination of a 632.8 nm He-Ne laser.Dr. Daniel Sola thanks the Ministry of Economy and Competitiveness of the State General Administration under the project MINECO FIS2013-41237-R and the PIT2 program of the University of Murcia´s own research plan for the financial support of his contract.Peer reviewe

    En este trabajo hemos utilizado y mejorado dos "juegos serios", ¿Cuál es mi caso? y Koro, diseñados por nuestro equipo para promover el aprendizaje de la Genética orientada a la Medicina. El análisis de las encuestas de valoración completadas por los participantes, estudiantes de Medicina y Bachillerato, demuestra la eficacia y la eficacia de las mejoras realizadas y la idoneidad de ambos juegos independientemente de su nivel de estudios . El equipo, además propone una nueva versión del juego ¿Cuál es mi caso? con mayor nivel de dificultad donde se incluyen objetivos formativos nuevos.In this work we have used and improved two "serious games", What's my case? and Koro, designed by our team to promote the learning of Medicine-Oriented Genetics. The analysis of the evaluation surveys completed by the participants, medical and high school students, shows the efficacy of our the improvements made and the suitability of both games regardless of their level of studies. The team also proposes a new versionof the game What's my case? with a higher level of difficulty and new learning objectivesSección Deptal. de Biología Celular (Medicina)Fac. de MedicinaFALSEsubmitte
