Surely it then follows (being as Canon have not changed the design of the dioptric correction lenses) that if adding a -4.0 dioptric correction lens, ON TOP of the dioptric correction you can 'dial in', then you can (with a camera giving +1.0 to -3.0 dioptres) get an equivalent of -7.0 dioptres??

The amount of attempted correction of the SE or astigmatism was correlated with the development of glare and halo symptoms. Pupil size was not significantly correlated with glare or halo symptoms, BSCVA, or contrast sensitivity in post-LASIK patients with "uniform" topography who had scotopic pupils not larger than 7.0 mm...

In addition, when dioptric correction is made for one eye, usually the other eye is closed while the adjustment is being made because the image seen by the other eye hinders the adjustment. Depending on the observer, however, dioptric correction may be made for both eyes with both eyes open.
