Susana Marcos is an acclaimed researcher in the field of visual optics and ocular imaging. She is a pioneer in the development of new techniques for the evaluation of the eye, including retinal imaging instruments, aberrometers, adaptive optics, anterior segment imaging of the eye and intraocular lens designs.

Marcos earned her Bachelor and PhD degrees in Physics at the University of Salamanca, Spain. Before coming to Rochester, she was Director of the Institute of Optics, CSIC (2008-2012), Spain, and Professor of Research at CSIC, where she founded the Visual Optics and Biophotonics Lab in 2000. Prior to her tenure at CSIC (the top research institution in Spain, and #7 public research institution in the world), she was a postdoctoral Fellow (funded by Fulbright and Human Frontier Fellowships) at the Schepens Eye Research Institute (Harvard Medical School).

In July 2021 she was appointed Director of the Center for Visual Science, with dual affiliation in Optics and in Ophthalmology at the University of Rochester. She holds a visiting professorship (doctor vinculado) at the Institute of Optics, where she supervises a multidisciplinary, international team of more than 25 members. Her research programs at the University of Rochester address emerging technologies for myopia, presbyopia, cornea and cataract corrections.

Marcos has published more than 210 highly cited research articles, and is the inventor of 23 patent families (14 licensed to the industry). Her research has been key in spin-off companies Plenoptika and 2EyesVision, which she co-funded in 2015. These companies commercialize the Quicksee and the SimVis technologies respectively.

AI offers clarity to LASIK patients facing cataract surgery

Ophthalmology Times  online


According to a University of Rochester news release, Susana Marcos, the David R. Williams Director of the Center for Visual Science and the Nicholas George Professor of Optics and of Ophthalmology at Rochester, pointed out the computational models that use anatomical information of the patient’s eye provide surgeons with important guidance on the expected optical quality post-operatively.

Effect of fixational eye movements in corneal topography measurements with optical coherence tomography

Biomedical Optics Express

Susana Marcos, Alberto de Castro, and Eduardo Martínez-Enríquez


There is an increasing interest in applying optical coherence tomography (OCT) to quantify the topography of ocular structures. However, in its most usual configuration, OCT data is acquired sequentially while a beam is scanned through the region of interest, and the presence of fixational eye movements can affect the accuracy of the technique. Several scan patterns and motion correction algorithms have been proposed to minimize this effect, but there is no consensus on the ideal parameters to obtain a correct topography. We have acquired corneal OCT images with raster and radial patterns, and modeled the data acquisition in the presence of eye movements.

Introduction to the Feature Issue on Adaptive Optics for Biomedical Applications

Biomedical Optics Express

Susana Marcos, Ramkumar Sabesan, Kate Grieve, Daniel X. Hammer, and Na Ji


The guest editors introduce a feature issue commemorating the 25th anniversary of adaptive optics in biomedical research. Adaptive optics (AO) has enabled unprecedented access to the basic building blocks of biology and medicine. Borrowing ideas and approaches from astronomy to measure and correct for optical aberrations, AO was first demonstrated in living biological tissue – the human eye – 25 years ago [1]. Since then, the use of AO in biomedical imaging has grown and expanded to applications in ophthalmology, vision science, microscopy, and neuroscience. This was made possible by technology development targeted for these specific application areas and fueled by a growing need to examine biological structures and processes at cellular and sub-cellular scales in living tissue.
