WaveDȳn Vision Analyzer


Streamline workflow with multiple
measurements in one system


The WaveDȳn Vision Analyzer is commercially available. The team is also developing processes of applying wavefront-based corrections to various vision correcting lens platforms for future commercialization.

Highly accurate objective refractions via dynamic acquisitions.1

The WaveDȳn objective refractions are based on the system selecting the highest quality measurement out of a sequence of measurements. 

  • The selected objective refraction is based on: SEQ, measurement quality, and pupil diameter.
  • The acquisition speed is user selectable, up to 120 frames/second.


WaveDȳn System’s fixation target automatically pre-adjusts for astigmatism to assist in managing the potential for instrument accommodation, facilitating highly accurate refractions. 1

Fixation target:

  • Cylinder: 0.00 D to 6.20 D (two decimal places) in any axis, 1-degree increments.      
  • Sphere: Fogging (-16 D to +12 D) instrument range, +/- 3 D target fogging.



Target brightness: Scotopic, mesopic, and photopic.

Data Viewer enables dynamic, playback video display of iris, wavefront, and CT maps for analysis.
  • Dynamic videos displays iris image, wavefront, and topo maps.
  • Displays 1, 2, 4, or 6 maps.
  • Refractive power displayed to hundredths of a diopter.
  • Refraction can be rounded to nearest 0.25 D.
  • Refraction is adjusted to clinic’s specific lane length.


Single step subjective refraction and VA, reduces exam time and improves accuracy.

1.System’s objective refraction & target are presented to the patient. 
2.Single step Subjective refinement and VA:
– Adjust Sphere, Cylinder, and Axis values.
–“Which do you see better, 1 or 2?”

An ultra high-resolution Shack-Hartmann wavefront sensor creates high definition wavefront measurements.
  • WaveDȳn’s 116 µm spatial resolution provides for a wide dynamic range and accurate measurements. 1

Wavefront images are of same eye measured on three separate instruments. Systems A and B are commercially available.
