Prof. Susana Marcos awarded Ramon y Cajal Medal by the Royal Academy of Sciences

Medalla Ramon y Cajal

The Royal Academy of Sciences, gathered in extraordinary plenary session on March 27, agreed to award the Ramón y Cajal Medal 2019, which rewards the trajectory of Spanish scientists under 50, to Prof. Susana Marcos. 

The jury of the award pointed that Prof. Marcos “has maintained an outstanding scientific career at an international level, with a fully multidisciplinary research program, using concepts of physics, optics, biology, biomechanics, ophthalmology and neuroscience to understand the basic mechanisms of human vision, develop diagnostic tools in ophthalmology and to invent new optical solutions for the correction of the most common vision problems. His work, highly productive both in the academic field and in technology transfer, has a high impact on basic science, the clinic and the ophthalmic industry”.

New in the Lab: Elena Campillo

elena

We welcome Elena Campillo (BSc in Physics, Universidad Complutense de Madrid) who joined Viobio lab with a Predoctoral Fellowship of YEI Program funded by Comunidad de Madrid. She performed her degree practises at IMDEA Nanoscience working at Hypertermia (cancer research with nanoparticles) continuing her final Bachelor Thesis at Instituto de Magnetismo Aplicado.

Elena holds a MSc in Biomedical Technologies Management and Development from the Universidad Carlos III de Madrid. She did her master thesis at Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (CIEMAT).

She will work on Perception and Psychophysics using optotunable lenses.

SILK-EYE, a new ERC Advanced Grant announced to VIOBIO Lab

Silkeye collage I

The European Research Council has announced this year’s ERC Advanced Grant projects, SILK-EYE led by Professor Susana Marcos (Visual Optics and Biophotonics Lab, Institute of Optics, CSIC, Spain) being one of the 10 new grantees from Spanish research institutions. This new ERC grant, follows ERC AdG PRESBYOPIA, ERC PoC OCT4IOL, ERC PoC SimVisSim and ERC PoC LightAIOL, previously granted to the group.

SILKEYE will develop a unique set of strategies for the generation of ocular implants based on silk biomaterials that are more biocompatible and versatile than current synthetic implants, and safer, more functional, more accessible and more affordable than allografts. The project will produce high impact results at the interface of photonics and biology, and has the potential to revolutionize how major corrective procedures in ophthalmology are performed.

Pablo Sanz Diez, MyFun ITN Marie Curie Fellow, secondment at VioBio Lab

VioBio Lab participates in the International Day of Women and Girls in Science

Post Mujeres

The VioBio Lab (Instituto de Óptica, CSIC) has joined the celebration of the International Day of Women and Girls in Science (commemorated on February 11th), which seeks to make visible the work of women scientists and promote new scientific vocations in girls.

Gadea Ciencia Foundation organized the round table “Women and Science” with Prof. Susana Marcos, María Blasco and Clara Benedí as invited speakers. During the debate they pointed the importance of a better education from an early age to change stereotypes and the need to normalize the presence of women in certain areas and careers. More information about the event in the next links:

Susana Marcos also attended the opening event of Women and Girls in Science’s Week organized by the Government of the Principality of Asturias and CSIC. The event also included the presentation of The periodic table of women scientists.

With the objective of showing feminine references in science, during two weeks CSIC has organized more than 200 activities throughout Spain. One of the multiple initiatives to celebrate this day, was to release videos of top researchers talking about their careers and why they became scientists. Here is the video featuring Susana Marcos and Carlos Dorronsoro. Finally, visitors to CSIC campus in Madrid will find new banners showcasting prestigious women scientists, including Susana Marcos. More information on all these initiatives can be found in the next article.

Extraordinary impact of Press Conference on SimVis on television and media

rueda de prensa

CSIC and VioBio Lab have presented the validation and launch of SimVis, a simultaneous vision simulator, in a press conference that took place yesterday at CSIC (Calle Serrano 113, Madrid). 

For the first time, patients who undergo cataract surgery will be able to experience how they will improve their vision after the surgery. Thanks to this portable simulator, developed by researchers from the VioBio Lab (CSIC), patients and surgeons have the possibility of seeing the effects of an intraocular multifocal lens realistically before the implantation. Details on the validation of this new device are published in the latest issue of Scientific Reports (Nature).

The technology has led to four patents (one of them received the Best Patent of the Year Award from the Madrid+d Foundation) licensed to 2EyesVision SL, a spin-off company from CSIC, funded, among others, by several of the researchers involved in the development of SimVis. 

“Visual simulators are an ideal technique to provide patients with a realistic experience of multifocality before the implantation of an intraocular lens. In addition, since the device has been reduced in size and has a more practical design than those currently in the market, the benefits multiply, ” Prof. Marcos concluded during the press conference.

First validation of the simulation of commercial intraocular lenses by SimVis, published in Scientific Reports

41598_2019_38673_Fig7_HTML

Multifocal intraocular lenses are used to provide patients to functional vision at various distances. In a recent paper published in Scientific Reports we demostrated the equivalency of through focus visual acuity with real lenses (a bifocal refractive IOL and a trifocal diffractive IOL) and the same lenses simulated in a Spatial Light Modulator and SimVis technology (temporal multiplexing).

Dynamic characterization and control of opto-tunable lenses, published in Optics Express

figuraspapercarlos

Tunable lenses are increasingly popular in applications including microscopy, optical coherence tomography, computer vision, quality control, and presbyopic corrections, some of them requiring an accurate control of the optical power of the lens in response to a time-dependent input waveform. In a paper recently published in Optics Express, we present a fast focimeter (3.8 KHz) to characterize the dynamic response of tunable lenses. We demonstrated the compensation of the temporal distortions in the transient responses of optotunable lenses, broadening their potential in high-speed applications. This approach used in the Sim+Vis technology, using a temporal multiplexing approach to simulate multifocal lenses used to correct for presbyopia.

Express 27, 2085-2100 (2019).
