2EyesVision, VIOBIO-CSIC Spin-off, announces Venture Capital investment


2Eyes Vision, spin off of the Visual Optics and Biophotonics Laboratory of the Spanish National Research Council (CSIC) has announced today a Series A investment led by Bullnet Capital. The investment will provide the company with the necessary resources to strengthen product development and to create a sales and marketing structure.

The SimVis technology is the result of a 7 year investigation and it allows cataract and presbyopic patients to experience, for the first time, the real world through multifocal corrections before contact lens fitting and intraocular lenses implantation, allowing the ophthalmologist to take a personalized decision on the lens to be implanted based on the patient’s preferences.

Quantization of collagen organization in the stroma with a new order coefficient, published in Biomedical Optics Express


A new order coefficient was introduced to quantize the differences in organization between three different types of treatment applied to porcine corneas: untreated corneas, UVX crosslinked corneas, and corneas treated with riboflavin.  Collagen fibers in the stroma were imaged through a depth of 700 mm using forward-scattering second harmonic generation microscopy.  Analysis points based on the orientation of the fibers were calculated and the number of points falling within 10° analysis windows was counted.  From these points, the order coefficient was calculated as the normalized variance of the number of analysis points in each window.  This quantization showed that the UVX crosslinked corneas were more ordered up to a depth of 400 mm in the stroma.
