"The innovation in the
LenSx Laser is that it has
a variable beam, such that
when it's working at the
corneal surface, it focuses
differently, from different
angles, than when it's
focusing deeper. So it
behaves both like a laser
that was made to work on
the lens and like a laser
that was made to work
on the cornea.

The wide beam is designed for corneal accuracy.
The LenSx Laser is helpful in patients with intumescent
white cataracts. The anterior chamber is fully inflated. As the
surgeon performs the capsulotomy, pressure in the anterior
chamber is maintained, and this helps prevent the tear from
running out to the periphery, which is common in these cases
when the capsulotomy is performed manually.
The fact that the chamber remains pressurized and the
fact that the capsulotomy occurs for 360 degrees almost in-
stantaneously help decrease the risk of having a radial tear.
