New in the lab: Hrebesh Shubash
We welcome Dr. Hrebesh Shubash, joining @VioBio_Lab as a senior investigator in the area of optical coherence tomography. Dr. Hrebesh gained his Ph.D. in Biomedical Optics form the Human Sensing and Functional Sensor Engineering Division of Yamagata University, Japan in 2008. His research interests are focused on the development and application of OCT based novel high-resolution optical imaging methods for disease diagnosis. He is also actively involved in developing a compact and cost-effective OCT platform for next generation personal & point of care applications. He has authored more than 80 peer-reviewed publications and conference proceedings and chapters in 3 textbooks on Biomedical Optics
A revolutionary technique to engage IOLs to the capsular bag based on photobonding, published in IOVS
The study presents a new paradigm for engaging an intraocular lens to the lens capsular bag, based on a photobobonding technique. Anchoring the haptics to the capsular bag is essential for the operation of accommodating of IOLs. The study demonstrates the possibility of achieving a strong bobding between a polymer material of standard use in IOLs with rabbit capsular bag. Photobonding was activated by Rose Bengal and photinitated by green laser light. The load producing bonding breakage was at least one order of magnitude above the forces available from the ciliary muscle. The study is a result of a collaborative effort between VioBio Lab and Wellman Center of Photomedicine (MGH/Harvard).

Native astigmatism biases subjective best focus setting, published in the Journal of Vision
The study, published in the current issue of Journal of Vision, explores the role of native astigmatism and ocular aberrations on best-focus setting and its shift upon induction of astigmatism in 42 subjects (emmetropes, myopes, hyperopes, with-the-rule and against-the-rule astigmats), using a custom adaptive optics system. Best focus shifted in opposite directions in WTR and ATR astigmats upon induction of astigmatism, symmetrically with respect to the best-focus shift in nonastigmatic myopes. The shifts are consistent with a bias towards vertical and horizontal retinal blur in WTR and ATR astigmats, respectively, indicating adaptation to native astigmatism. The study is part of a collaboration between VioBio Lab and Essilor International.
