Added Safety in Phaco Emulsification
The instrument can be used before and/or after retrobulbar, peribulbar or subtenons anesthesia. Application after injection
anesthesia, or pledgets soaked in topical anesthetic solution and positions in cul-de-sacs, can enhance the effect of the
anesthesia. Softening the eye, by presurgery ocular compression prior to phaco emulsification in small incision, no-suture surgery,
can be a safety feature in occasional cases where conversion to extracapsular or intracapsular surgery is necessary.
Preoperative ocular compression may be a safety measure in preventing choroidal expulsive hemorrhage. Sudden stress
occurs on fragile sclerotic vessels when the intraocular pressure is suddenly reduced to atmospheric pressure at the time of
incision. Lowering the intraocular pressure by preoperative ocular compression should reduce the pressure differential and the
amount of stress on the vessels at time of incision.

GUIDELINES FOR USING
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.
The optimum pressure to be used should be well below pressure in the central retinal artery. It should be elevated only high
enough to create a soft surgical eye. Using the 20 to 30 mm Hg of monitored pressure for 30 to 60 minutes before surgery,
clinically results in very soft, safe, surgical eyes. With the Schiotz Tonometer with 5.5 gram weight, the scale reading may be
above 10. An eye may be so soft that the cornea may be observed to dimple when the lid speculum is inserted. Releasing the
pressure every 30 seconds and then reapplying it has NOT been found necessary or desirable.
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.
Preparation for use
Clean and disinfect the Headband, Bellows and Tubing (parts that
touch the patient’s face) using CaviCide® (from Metrex), Matar®
(from ECOLAB, INC.) or a recognized germicidal solution.
Wipe clean. Do not immerse. Do not autoclave or gas sterilize.
INSTRUCTIONS FOR USING RELIEF VALVE WITH
HONAN INTRAOCULAR PRESSURE REDUCER
This 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 gauges 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.
A. Connect valve inlet to gauge with short rubber tubing which is on valve.
B. Connect valve outlet to bellows with long rubber tubing.
If valve is received with new Pressure Reducer it will come connected to bellows with long tubing; and directions, “A” will be followed.
If valve is purchased to be added to reducer already in service disconnect long tube from gauge. Then follow directions, “A”, and “B”.
Before applying bellows to the eye, pump vigorously a few times to assure secure seating of the valve to prevent air
leaking. Then release all air. Apply bellows to eye and gently inflate to pressure desired by surgeon.
