Clinical evaluation of the Quicksee low-cost hand-held autorefractometer, published in OVS

 

 

We describe a newly developed Hartmann-Shack autorefractor and demonstrated equivalent performance to the Grand Seiko
autorefractor in matching power vectors measured by subjective refraction. Because the QuickSee can
be produced at low-cost without a sacrifice in accuracy, it is a promising new approach to refraction that
may someday make autorefractors more accessible to resource-constrained eye care providers. The study results from a collaboration between VioBio Lab (CSIC), New England College of Optometry and Massachussets Institute of Technology under the Madrid MIT M+Vision Consortium. Quicksee is being commercialized by Plenoptika, Inc. The paper is published in the current issue of Optometry and Vision Science

Chromatic aberration of hydrophilic and hydrophobic IOLs, published in JCRS

 

 

Using a polychromatic adaptive optics system, we measured psychopysically and objectively the longitudinal chromatic aberration (LCA) in eyes implanted with two IOLs of same design, but different materials (from PhysIOL) in a wide spectral range. Hartmann-Shack based LCA was consistently lower than the psychophysical LCA. Longitudinal chromatic aberrations were smaller with hydrophilic IOLs than with hydrophobic IOLs of the same design. The study was supported by PhysIOL through a collaborative agreement, and counted with the clinical support of members of the Instituto de Oftalmologia Avanzada. The paper is published in the Journal of Cataract and Refrative Surgery.
