Guess Just to me it was a new term.
This is not new news. The glistenings were reported with the Acryosof Alcon IOL in the mid and late 90's. It is NOT clinicallly significant and is NOT the reason for night blindness, flare, rays, halos and other dysphotopsia.
It is the design of the IOL that creates the many problems of multifocal IOLs.
