THE BEST WAY TO
LOWER
INTRAOCULAR
PRESSURE BEFORE
SURGERY
LOWER
INTRAOCULAR
PRESSURE BEFORE
SURGERY
GUIDE LINES 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.

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. Application after injecting anesthesia solutions can help prevent retrobulbar or peribulbar
hemorrhages. 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.
