precautions
This
instrument
has
been
developed
and
tested
in
accordance
with
Carl
Zeiss
safety
standards
and
with
national
and
international
regulations.
A
high
degree
of
instrument
safety
is
thus
ensured.
It
is
recommended
in
these
regulations
that
the
manufacturer
explicitly
informs
the
user
about
the
safety
aspects
of
operating
the
instrument.
This

Phototoxic
Retinal
Damage
in
Eye
Sur-
gery
General
Several
papers
have
been
published
dealing
with
the
problems
of
phototoxicity during
eye
surgery.
A
comprehensive
review
of
these
publications
re-
veals
five
aspects
of
particular
concern:
—
Illumination
characteristics
(spectral
composi-
tion)
—
Intensity
of
illumination
=
Angle
of
illumination
=
Focus
of
the
light
source
=
Exposure
time
to
the
light
In
the
following,
comments
on
these
aspects
are
given
and
a
description
how
Carl
Zeiss,
as
a
man-
ufacturer,
makes
allowance
for
them
in
its
instru-
ments.
Illumination
characteristics
(spectral
composi-
tion)
Studies
on
exposure
of
the
eye
to
light
of
varying
spectral
composition
date
back
to
the
early
1950's.
These
studies
suggest
that
the
potential
hazard
of
phototoxic
damage
to
the
patient's
retina
can
be
reduced
by
blocking
out
the
blue
and
ultraviolet
light
below
a
wavelength
of
475
nm.
Carl
Zeiss
provides
a
GG
475
eye
protection
filter
for
surgical
microscopes
recommended
for
use
in
ophthalmic
surgery.
This
reduces
not
only
the
light
exposure
of
the
patient's
eye,
but
also
that
of
the
‘surgeon's.

It
should
be
noted
here
that
the
use
of
filters
will
of
necessity
cause
a
change
in
the
color
of
ilumina-
tion.
The
physician
may
need
to
become
familiar
with
the
resulting
changes
in
the
appearance
of
anatomical
structures.
Intensity
of
illumination
The
majority
of
researchers
suggest
that
the
sur-
geon
should
use
the
lowest
light
intensity
neces-
sary
to
guarantee
good
viewing
during
surgery.
Carl
Zeiss
has
addressed
this
concern
by
provid-
ing
a
device
for
continuously
varying
the
bright-
ness
of
the
light
source.
The
physician
is
thus
able
to
perfectly
adapt
the
light
intensity
at
the
patients
eye
to
the
conditions
existing
in
each
case. Zeiss
strongly
discourages
the
use
of
xenon
or
other
high-intensity
light
sources
in
ophthalmology.
Angle
of
illumination
A
number
of
publications
suggest
that
the
micro-
scope
should
be
tilted
to
reduce
the
exposure
of
the
macula
to
direct
illumination.
Carl
Zeiss
ophthalmic
surgical
microscopes
are
therefore
equipped
with
the
following:
=
Tilting
mechanism
for
microscope
body
=
Oblique
illumination
with
intensity
control
Focus
of
the
light
source
‘Studies
show
that
damages
are
likely
to
occur
if
the
filament
of
the
light
source
is
imaged
on
the
patient's
retina.
The
resulting
macular
edema
will
duplicate
the
pattern
of
the
illuminating
filament.
The
peak
intensity
of
the
filament
image
is
much
higher
than
the
peek
intensity
of
an
even
and
ex-
tended source
like
a
fiber
guide.
Carl
Zeiss
therefore
recommends
the
use
of
fiber
optic
illumination
for
axial,
coaxial
and oblique
illu-
mination.
This
provides
the
surgical
area
and
the
retina
with
even
and
diffuse
light.
Exposure
time
to
the
light
According
to
some
publications,
the
phakic
or
aphakic
eye
should
not
be
exposed
to
the
light
source
longer
than
a
few
minutes.
In all
surgical
cases,
the
retinal
exposure
time
depends
to
a
great
extent
on
the
surgical
technique,
the
effi-
ciency
of
the
surgeon
and
possible
case
complica-
tions.
It
is
therefore
recommended
in
ophthalmic
surgery
to
keep
the
light
intensity
as
low as
possi-
ble, or
to
use
a
device
which
prevents
light
from
entering
through
the
patient's
pupil.
Also,
the
sur-
rounding
light
sources
should
not
cause
additional
strain
to
the
eye.
Carl
Zeiss
has
provided
an
answer
to
this
problem
in
the
form
of
a
swing-in
retinal
protection
devi
for
insertion
into
the
beam
path
of
the
surgical
croscope.
This
device
ensures
total
eclipsing
of
the
pupil,
preventing
light
from
entering
through
it.
It
can
be
swung
out
when
a
red
reflex
is
required.

In
conclusion
Carl

recommends:
—
Use
of
the
GG

protection
filter
=
Reduction
of
the
illumination
of
the
surgical
ar-
ea
to
the
extent

ty
and
for

=
Tilting

—
Insertion
of
the

device
—
Reduction
of
the
patient's
eye
to

expo-
sure from

These
measures
should
help
the

to

damage.
