Research

Experience in designing and building optical imaging instruments, including double-pass technique, ocular aberrometry, ocular biometry (Purkinje, Scheimpflug imaging, OCT), adaptive optics, high resolution retinal imaging, retinal reflectometry and microscopy. Custom-development of optics, electronics & mechanical.

Measurements of monochromatic and chromatic aberrations. Assessment of optical quality in normal, pathological (i.e. keratoconus), and treated eyes (refractive surgery, contact lenses, intrastromal ring segment, IOLs).

Measurement of anterior and posterior corneal and lens topography, 3-D biometry, lens misalignment, GRIN (in vitro)

We have developed analytical tools for customized intraocular lens design. In addition, we have experience in assessing optical properties in vivo in eyes with intraocular lens implanted, as well as measuring optical performance of IOLs in custom-designed water cell models, and customize computer modelling of pseudophakic eyes.

Water-cell model eyes for instrument validation and lens testing. Experience in measurements on a wide range of animal models in vivo and ex vivo.

Custom develop eye inflation models; Scheimplug-based and OCT-based air puff corneal deformation testing. In normal and treated (cross-linking) eyes.

Finite-element modeling for retrieval of corneal biomechanical properties (elastic and viscoelastic parameters), as well as for intraocular lens assessment and design

Visual simulation through manipulated optics (aberration correction, combinations of aberrations, presbyopic corrections) in Adaptive Optics custom-development instrument. Psyschophysical routines for measurement of visual function, visual perception and neural adaptation
