We report good correlations between MTF and CSF improvements upon AO-correction of high order aberrations (both in spatial frequency and across orientations). However, the visual benefit was consistently lower than the optical benefit, suggesting limits imposed by the neural transfer function to the achievable improvement in contrat perception.
The study is the result form a collaborative work between the Visual Optics and Biophotonics Lab and David Atchison's lab at Queensland Institute of Technology. The full study can be found at: Journal of Vision October 10, 2011 vol. 11 no. 12 article 5
