Glassy look in other people's eyes from cataract lenses

Many times at night, when I'm in a group of older people, I see a strange glassy circle in the center of each person's eyes from their cataract lens. These people had their surgery several years ago (it's now 2018); is this something that still happens from the surgery or are there new lenses that don't create this strange look? I'm almost ready for the surgery but am waiting until I'm sure I won't have that look, too.
