Intraocular photobonding of intraocular lenses published in Translational Vision Science and Technology

Imagen1

Accommodating Intraocular Lenses are enabled by the engagement of the haptics with the peripheral region of the capsular bag. In a previous work we demonstrated photo-activated strong bonding of the capsular bag and polymer material. We have now proved intraocular photobonding, compliant with standard cataract surgery, using Rose Bengal as a photo-activator and green light for photoirradiation.

The work is published in the October 2018 issue of the ARVO journal Translational Vision Science and Technology.

MyFun Marie Curie Outreach Activity by IOSA Student Chapter at the Royal Botanical Garden

Flyer

IOSA Student Chapter is organizing a very special event that will be part of the ITN Marie Curie MyFun Summer School 2018 held in Madrid. The event will be an outreach activity in which early-stage researchers from around the world will explain myopia to the general audience through different workshops. The activity will take place Tuesday 16th from 17h to 19h at Real Jardín Botánico (Plaza de Murillo 2, Madrid).

IOSA is the OSA-EPS student chapter at the Institute of Optics (CSIC), composed of young researchers working on optics and physics, actively involved in broadening their scientific knowledge among the general population.

MyFUN (“Myopia: Fundamental Understanding Needed”) is an Innovative Training Network (ITN) funded by the European Commission’s Horizon 2020 programme under the Marie Skłodowska Curie Actions.

The Royal Botanical Garden of Madrid is a research center of CSIC founded in 1755. Its mission is to promote the knowledge and conservation of plants and their natural environment.

VioBio Lab will be hosting the 2018 Summer School and Annual Meeting (16-19 October) at the Institute of Optics in Madrid. The program will feature hands on applications of optical technologies in ophthalmology and novel treatments for myopia. Invited lectures include Prof. Andy Yun (Wellman Center of Photomedicine, MGH-HArvar, USA), Prof. Sally McFadden (University of NewCastle, New SouthWales, Australia), Prof. Christine Wildsoet (UC Berkeley, USA), Prof. Don Mutti (Ohio State University, USA), and Prof. José González-Meijome (University of Minho, Portugal). Other contributions will come from MyFun Marie Curie Principal Investigators, VIOBIO Lab Members and MyFun Fellows, as well as a outreach activity by IOSA Student Chapter. 

MyFUN (“Myopia: Fundamental Understanding Needed”) is an In Innovative Training Network funded by the European Commission’s Horizon 2020 program under the Marie Skłodowska Curie Actions, comprising seven European universities, research institutions and companies. 

María Viñas, selected OSA Ambassador 2019 by the Optical Society of America

OSA Ambassador Maria

Dr. María Viñas, a postdoctoral researcher at the Visual Optics and Biophotonics Lab, has been selected OSA Ambassador for 2019. The Optical Society Ambassadors will share their experiences with students and early career professionals in the field. They will provide mentorship and technical knowledge through serving as a traveling lecturer for chapters and sections, supporting professional development events at OSA meetings.

Congratulations María!

New in the lab: Alessandra Carmichael

Alessandra

We welcome to VioBio Lab Alessandra Carmichael Martins, visiting Fellow of the MyFun Marie Curie ITN. Alessandra holds a Bachelor in Physics from the University of Seville, having been a student at Universidad Complutense de Madrid for one year during this time, and a MSc in Optics and Photonics from Imperial College London, UK. She is currently a ITN Marie Curie Fellow from the MyFun Network in the Advanced Optical Imaging Group at University College Dublin, Ireland, under the supervision of Brian Vohnsen. During her secondment at VioBio (CSIC) she will be working on manipultating the optics and Stiles-Crawford Effect with Adaptive Optics systems.

Impact of IOL decentration of different aspheric IOL designs on optical quality

Captura

An experimental model eye was used to study the impact of intraocular lens decentration on optical aberrations (astigmatism and coma) and optical quality (MTF and Strehl) with different state-of-the-art aspheric IOLs. We found that the increase in aberrations/reduction of optical quality upon decentration depends on the specific IOL design, with the Vininex (Hoya XY1) being the most immune design to decentration. The study has been published in the Journal of Cataract and Refractive Surgery.
