• X1 Ready-Loaded Iris Speculum. Diamatrix launched its X1 Ready-
Loaded Iris Speculum, so named because it comes prepackaged in an
injector. To use it, the surgeon injects the ring, engaging the leading
hook into the distal iris. As the speculum emerges from the injector,
the surgeon watches to make sure the lateral hooks engage on both
sides. The surgeon leaves the last hook on top of the proximal iris and
then engages it using an instrument called the Williamson hook. Dr.
Mahootchi did some practice maneuvers with the device, liked it and
plans to soon try it.
Diamatrix President Ron Dykes, who invented the device, says the
ring creates the widest opening of any device on the market and says
it's very gentle on the iris. The ring opens the pupil to 6.7 mm. The 4
"cradles" are said not to pinch the iris margin, so you can actually
rotate the speculum in the eye without rubbing off pigment. The
devices come 4 to a box.
