  • Refraction shifts to More Myopia as Accommodation is defined as a purely Spherical offset

  • Refractive Range Increases (i.e. More Depth of Field – Psuedo Accommodation)

Summary
Summary Difference Maps

The Examples above demonstrate that the Tracey 3-D Refraction Maps with Difference Map Objectively quantifies both Accommodation and Psuedo Accomodation Refractive changes in the normal and psuedophakic Eye.
