Slide 11 of 19

Notes:

So here is our suggestion. We propose that a VSIA taskforce be formed and charged with developing consensus recommendations on the following issues.

• Preferred describing functions and conventions for specifying the wavefront aberration function and the pupil transmission (or apodization) function, which together describe the eye's pupil function.
• Reliable algorithms for converting describing functions from all commonly used systems to the preferred functions, and visa-versa.
• Appropriate choice of reference axis for reporting pupil functions of eyes.
• Standard data sets suitable for testing computer algorithms designed to compute coefficients of the pupil aberration function and the pupil transmission function and related metrics of image quality.
• Design specifications for the construction of physical model eyes suitable for testing experimental methodologies for measuring the eye's pupil function.
• A procedure by which the vision community can create a "gold standard" model eye suitable for calibration of experimental systems.
• A procedure for periodic review and refinement of the taskforce's recommendations.
