The buzz surround-
ing negative dyspho-
topsia (ND) contin-
ues to build, specifi-
cally regarding the
tools surgeons may
soon have to treat it.
We continue to hear
about progress
being made in man-
ufacturers' quest to
build devices that
may help to detect
the presence or
extent of ND.
Perhaps the most compelling advancement may come in the
form of new IOL designs that can prevent ND from even becom-
ing an issue. A small number of anti-dysphotopic IOLs have
already come into play in Europe, one of which is the Morcher
90S IOL, derived from a U.S. patent. This IOL, which I developed
and licensed, has a circumferential groove on the anterior optic
that lets the optic overlap the anterior capsulotomy.
Although the lens is not yet available in the United States, it has
earned the CE mark — Europe's version of FDA approval — and
has shown strong initial clinical results: nearly 90 cases, from 3
months to 3 years, with no instances of ND.

NEGATIVE DYSPHOTOPSIA
Can Anti-dysphotopic IOL Prevent ND?
• PROGRESS Surgeons may soon have access to IOL designs capable of pre-
venting negative dysphotopsia.
