Research Overview

Dr. Huxlin directs the research efforts of two separate laboratories at Flaum Eye Institute. In the visual training and rehabilitation lab, the goal is to understand the cellular basis and psychophysical characteristics of visual perceptual plasticity in adulthood. Of particular interest is contrasting the plastic potential of intact visual systems with the visual plasticity that can be attained by adult visual systems that have sustained permanent damage at different levels of their hierarchical organization. One avenue of research currently being pursued is to use anatomical tools, molecular biology, visual psychophysics, virtual reality and functional imaging (fMRI) to characterize changes at the cellular and systems levels that are key to the recovery of visual functions after brain damage in adulthood. The laboratory has recently begun applying this knowledge to patients with visual cortical damage following stroke, tumor or trauma with the ultimate goal of developing behavioral and pharmacological strategies to promote visual recovery following such damage.

The second laboratory deals with corneal wound healing and physiological optics. This work is intended to provide new insights into the biological causes and perceptual consequences of increased optical aberrations in the eye following manipulations or the ocular surface, including laser refractive surgery and corneal transplantation. Using anterior segment optical coherence tomography, in vivo confocal imaging, wavefront sensing, histology, cell culture and molecular biology, we are beginning to understand the relationship between different aspects of ocular wound healing and optical quality in the eye. This knowledge is essential for the ultimate development of both intra- and post-operative strategies to improve the optical outcome of ocular surgeries and wounds. The laboratory is also developing a revolutionary new refractive method called IRIS (for Intra-tissue Refractive Index Shaping). IRIS uses a low-energy, high-repetition rate femtosecond laser to non-invasively alter the refractive index and optical properties of different ocular IOLs. Because it does not cause tissue damage or cell death, IRIS offers great promise as a novel tool to non-invasively customize refractive power and higher order aberration correction without the side effects normally induced by wound healing.
