Perceptual impact of astigmatism induction in presbyopes, published in Vision Research

AO Image_CB

Using an Adaptive Optics system, we investigated the effect of induced astigmatism on subjective best focus and on visual acuity in subjects of different ages (pre-presbyopic and presbyopic) and with different refractive profiles (emmetropes and astigmats). The custom-developed Adaptive Optics system allowed correction of high order aberrations and induction of astigmatism. The article published in Vision Research shows that the findings may be connected to long term exposure to astigmatism in astigmats and corrected presbyopes.

New in the lab: Amal Zaytouny

Amal

We welcome Amal Zaytouny who joins VioBio Lab and 2EyesVision under the Industrial Doctorate Program funded by Madrid Regional Government. The program aims at strengthening the competitiveness of Madrid companies by promoting collaboration and knowledge transfer between the academic world and the business world.

Amal holds a BSc in Optics and Optometry and MSc in Optometry and Vision Science from Universidad Politécnica de Catalunya. She has previous experience in the clinical area (Hospital de la Santa Creu i Sant Pau, Barcelona) and has performed an internship in the Medical Department of Alcon, where she worked in the field of intraocular and contact lenses, as well as in refractive surgery. 

VioBio Lab and 2EyesVision celebrate South Summit Award and new office space

2eyesvision-696x542

2EyesVision, spin-off company of the Visual Optics and Biophotonics Lab (CSIC), was selected, among more than 3.5 thousand start-ups, as the winner of the Healthcare and Biotech category of the South Summit 2019, the leading meeting on entrepreneurship and innovation that brings together startups, corporations and investors, organized by South Summit-Spain Startup, powered by IE University and co-organized by the Madrid City Council in collaboration with BBVA, Endesa, Wayra, Sabadell and Google. During the event 2EyesVision was also selected as one of the 10 most innovative start-up companies in Spain. 

To celebrate this recognition and the relocation of the company’s offices, 2EyesVision  held yesterday an event in the new space located in Tres Cantos (Madrid) attended by the staff, partners and investors of the spin-off company.

Morphological changes of the human crystalline lens in myopia, published in Biomedical Optics Express

OCT_GM

Custom quantitative 3-D OCT has been used to image the full crystalline lens in vivo in young myopes. We found that with myopia (and increased axial length) lens thins, equatorial, and capsular stretch while keeping constant volume. Axial elongation appears counteracted by a crystalline lens power reduction, while corneal power remains unaffected.
