Honan Balloon: Intraocular Pressure Reducer |
The best way to lower
intraocular
pressure before surgery
With a soft eye, the iris may be concave or drop posteriorly after lens removal.
Excess vitreous pressure is
typically absent. Intraocular lens implantation is much easier and safer.
From the surgeon’s viewpoint,
there is much less stress and strain.

Pressure on the eye traditionally has been a method of slowing some tachycardias.
Some persons may be
more sensitive to the ocular-vagal reflex. Therefore, all patients
should be monitored for signs of
bradycardia while pressure is being applied to the eye.

PRESSURE RELIEF VALVE
A highly sensitive precision finished relief valve will limit to approximately 60 mm Hg, the pressure that can be applied to the Honan Intraocular Pressure Reducer.
It is permanently adjusted and is designed to prevent pressure in the bellows from
exceeding approximately 60 mm Hg, even if the gauge should become damaged by
rough handling, dropping, etcetera. It will hold 20 - 40 mm Hg pressure as desired
for as long as the Surgeon deems necessary.
It is easily added to any Pressure Reducer now in service.
