Forward light scatter analysis of the eye in a spatially-resolved double-pass optical system.
Bottom Line: An optical analysis is developed to separate forward light scatter of the human eye from the conventional wavefront aberrations in a double pass optical system.We prove an additivity property for radial variance that allows us to distinguish between spot blurs from macro-aberrations and micro-aberrations.When the method is applied to tear break-up in the human eye, we find that micro-aberrations in the second pass accounts for about 87% of the double pass image blur in the Shack-Hartmann wavefront aberrometer under our experimental conditions.

Mentions: The post-TBU radial variance maps in Fig. 10(b) can include the scatter of the eye that may not be related to TBU . To see the change in light scatter attributable to TBU, we compute the Post-Pre TBU difference maps (Fig. 11Fig. 11
