Intraocular Pressure Devices
Prior to ophthalmic surgery, pressure within the eyeball can be reduced to simplify surgery. Historically mercury-filled balloons have been
used for this procedure. Approximately 175 grams of elemental mercury is poured into a small balloon the size of a large egg, then double
or triple bagged. When placed on the eye, the weight of the mercury on the eyeball keeps fluid from accumulating at the normal rate,
softening the eyeball prior to surgery.
Newer micro-surgical procedures have relegated this device to forgotten drawers in most facilities because pressure reduction is not
always necessary. The stored pressure reducer may create a waste problem because it may be easily discarded inappropriately due to its
small and inconspicuous size.
As use decreases, these devices have been found shoved to the back of cabinets or drawers, often in the Outpatient Surgery area, and
forgotten. Effort must be exerted to search for these unused items and to properly dispose of them while the hospital is actively involved in
their mercury elimination project. A similar device has been seen consisting of a hard, formed plastic egg with one convex side that
snapped to a headband. Many staff consider the device inferior. The concern is that a less adequate device, like the hard plastic egg will
not be used and the mercury-filled devices will be brought back into service. Without a replacement available, physicians may request
repair of one of the old-style mercury pressure reducers, unnecessarily exposing staff and patients to possible elemental mercury
exposure.
No manufacturer could be found that is still making mercury pressure reducers, and no recycling programs are in place for them. It is the
responsibility of the facility to find, recycle, and replace these devices. If a replacement is desired, the Lebanon Corporation offers the
Honan Intraocular Pressure Reducer or Eye Softener. It is a pneumatic device with a pressure gauge to maintain even pressure on the
eyeball.
