Plus, he also uses a
combination humidifier/dehumidifier system to
add or remove moisture from the air as
necessary.

Dust and Airborne Particles:
Obviously dust and other airborne particles can
cause infections.

Just like humidity, invisible
dust or airborne particles may come in contact
with the eye during surgery and cause an
infection later on. This is why the air in the
room is exchanged a minimum of two times every
five minutes. Dr. Patterson's system for doing
this is one of the most advanced of its kind,
and also includes a HEPA filtration system which
filters the dust and particles out of the air at
the same time.

Temperature Control: In
conjunction with humidity control, temperature
control is important in consistent successful
outcomes. Dr. Patterson maintains a constant 68°
in the room at all times. The surgery center
features a digitally controlled heating,
ventilation and air conditioning system with
graphical software and telelink modem. Dr.
Patterson controls the temperature to plus or
minus 1/10 (one-tenth) of a degree.

General Cleanliness: In order
to maintain general cleanliness and sterility,
the room has to be constructed with special
flooring and paint. Why? So it can withstand the
harsh cleaning agents required to maintain a
sterile environment.

Dr. Patterson's floor covering
is an operating room grade, low porous vinyl and
the walls are covered with an epoxy-based paint.
The ceiling is constructed with a
non-particulate material with a vinyl veneer
which enables the ceiling to be cleaned.
