Figure 7-54: Topo-Aberrometries at several accommodations in the Scout software: 

far accommodation 0D (

∞) and near accommodation at 3.5D (30 cm) and 5D (25 cm).

ACCOMMODATION TEST [ACCOMMODATION] 

By selecting [Accommodation] in the initial screen shown in Figure 7-1, it is possible 
to  run  a  test  that  repeatedly  measures  the  eye's  aberrometry,  starting  from  the 
"remote point" and at progressive near accommodation distances.  
The amerotropy, that is the “defocus” (= sphere-equivalent, at VD=0) of the remote 
point,  that  can  be  measured  with  [Auto  Rx]  or  set  manually  with the cursor, is the 
one shown in the lower left (ex. -2 D in in Figure 7-55).
