Sabine Kling will defend her thesis entitled “Corneal biomechanical properties: measurement, manipulation and simulation”
Sabine Kling will defend her thesis entitled “Corneal biomechanical properties: measurement, manipulation and simulation” next January 30 at the University of Valladolid School of Medicine, as part of the PhD Interuniversity Program in Visual Sciences. An open seminar will take place at the Insitute of Opitcs on January 29.

3-D evaluation of Accommodating Intraocular Lens Shift and Alignment In Vivo, published in Ophthalmology
Full quantitative 3D OCT is used to completely evaluate performace of the Crystalens Accommodating IOL. Cornea curvature, anterior chamber depth, lens thickness, crystalline lens and IOL 3-D alignment were measured in 22 eyes pre- and post-operatively.
High-resolution OCT measurements of the Crystalens 3-D positioning revealed small (and in many patients backward) A-IOL axial shifts with both natural or drug- induced accommodation, as well as tilt changes with respect to natural lens and accommodative effort.

OCT Purkinje-like method for lens tilt and decentration measurements, published in Optical Engineering
Measurement of tilt and decentration of implanted intraocular lenses (IOL) is important to assess surgical outcomes. We present and validate a method that joints the advantages of OCT and Purkinje imaging to measure IOL alignment in vivo. The tomographic nature of OCT allows unequivocal identification of the anterior cornea and anterior and posterior IOL reflections in en face OCT images. The online advanced publication is available. On print, it will be part of the Special Issue on Human Vision, to be publised by Optical Engineering in June 2014
