7 mm is a huge pupil and very few people have that big of pupil even in pitch dark, this is especially true as we age. Biggest pupils are found in teenagers. pupils are very small in infants and in the very old.
Pupil size is more imporant in lasik than cataract surgery.
Worse case is that alphagan P can be used at night to keep the pupil from getting fully dilated.

I see,
So if the pupil were 7 mm, there would be no problem? What about seeing the edge of the lens? I have heard of that phenomenon before.
Most IOLs are 5.5 to 6.0 to 6.5 mm
The pupil would really have to be big to create a problem. Very few pupil have pupils that big. Most problems with halos and starbursts are due to IOL decentration, or dysphotopsia from the IOL which in turn is much more common in the accommodating/refractive "premium" IOLs
