Instruments: Five Poems on the Body and Medical Care

Instruments

A verse companion to SLIT LAMP.
Five tools. Five small negotiations
between the body and the word care.

---

I. The Slit Lamp

Named for what it does
to light.

Takes the broad, democratic brightness
of the examination room
and narrows it
to a blade,
a focused argument,
a beam that says:
here. This specifically.

The slit lamp does not illuminate everything.

This is the point.

Illuminating everything
produces nothing useful.
You need the discipline of the narrow beam,
the precision of the chosen angle,
the willingness to look at one thing
with complete attention
and let the rest
remain in the dark.

Most instruments could learn from this.

Most people could.

---

You put your face in the chin rest.

I put my eye to the eyepiece.

We are four inches apart
in the dark of the examination room
and I am looking at the interior
of your eye
with a concentration
that borders on the intimate
and is classified, professionally,
as clinical.

The classification is accurate.

It is also insufficient.

---

What the slit lamp finds:
the structures.
The cornea, the anterior chamber,
the lens, the posterior segment.
The legible interior
of a thing
that spent its whole life
looking out
and is now,
for eleven minutes,
being looked into.

What the slit lamp misses:
everything in the dark
outside the beam.

Which is most of you.

Which is always
most of you.

---

II. The Phoropter

The question it asks
is the oldest question:

Which is better.
One.
Or two.

It asks this
fourteen times per eye,
rotating the lenses
with the unhurried patience
of something that has
all day
and has learned
that rushing the answer
produces the wrong prescription.

---

Which is better.

The patient squints.
The patient second-guesses.
The patient says one
and then says actually two
and then says they look the same
which is not an answer
and is also
the most honest thing
anyone has said
in this room today.

The phoropter is teaching you
something about perception
that has nothing to do with vision:

that better is not always obvious,
that the difference between clear
and almost clear
is detectable only under ideal conditions
by a patient who has learned
to trust the increments,

and that most of us
have been living with
almost clear
for so long
we've stopped knowing
what clear looks like.

---

The phoropter knows this.

The phoropter rotates
to the next option
without judgment.

One.

Or two.

Take your time.

---

III. The Occluder

Such a plain instrument.

A paddle.
A handle.
An opacity.

It covers one eye
to test the other,
to find out what each lens
can manage
when it is not being
compensated for
by its neighbor.

This is the instrument
of individual accountability.

---

The covered eye
goes dark.

The uncovered eye
performs alone,
reads the chart alone,
reports what it sees
without the assistance
it has been receiving
so long
it forgot
it was assistance.

Sometimes the uncovered eye
is stronger than expected.

Sometimes it has been
quietly carrying more
than its documented share
for years
and nobody checked
because together
they were managing
fine.

---

The occluder is not cruel.

The occluder just wants to know
what you can do
on your own.

Which is a question
worth asking.

Which is a question
worth being able to answer.

Cover the other eye.

Read the line.

Tell me what you actually see
when you are not
being compensated for.

---

IV. The Applanation Tip

This one touches you.

The others look, measure, rotate,
offer their lenses and their light
and their paddles
without contact,
maintaining the professional distance
of instruments that examine
without entering.

The applanation tip
touches the cornea.

Briefly.
With fluorescein staining
the tear film gold.
With the blue light
making the contact point visible,
two semicircles meeting
at the point of touch,
the instrument reading the pressure
of the eye's interior
through the surface it presses.

---

You have to not blink.

This is the hardest part.

The body's oldest reflex,
the one that fires
before the conscious mind
has finished deciding anything,
the blink that says:
something is coming,
something is at the threshold,
close.

You override it.

You hold the eye open
through will
against instinct
and let the instrument touch
the most exposed surface of you
because the measurement matters
and the measurement requires contact
and contact requires
letting something
past the reflex.

---

The pressure reading takes three seconds.

Three seconds of touch
at the surface of the eye,
the instrument reading
the weight of what's inside you
by pressing
from outside.

This is either
a perfect metaphor
or a tonometry procedure.

In this office,
it is both.

---

V. The Speculum

Let's be honest about this one.

The speculum is the instrument
that holds you open
when open is necessary
and not, precisely, chosen.

The lid speculum, specifically:
a small hinged mechanism
that props the eyelid
beyond its natural range,
beyond the range you would hold it
voluntarily,
past the point of comfort
into the territory of necessity,
because the procedure requires access
and access requires
more openness
than the body
would otherwise volunteer.

---

It does not hurt.

This is what they tell you
and it is accurate
and it is also not
the whole story,
because hurt is not
the only relevant variable
when something is holding you
open beyond your preference.

There is the matter of control.

The speculum removes it.
Not cruelly.
Not carelessly.
With the efficient
necessity of an instrument
that has a job
and does it
without apology.

---

The speculum is the instrument
that does not ask
whether you would like to close.

It knows you would.

It holds you open anyway.

Because the procedure requires it.
Because care sometimes requires
access you would not grant willingly.
Because the body's instinct to close
is not always the body's wisdom,
and the job of the instrument
is to know the difference.

---

After the procedure,
when the speculum is removed,
the blink is involuntary
and total.

The eye closes
with the full force
of everything it was holding back,

and then opens again,
on its own terms,
at its own pace,

into whatever light
is waiting.

---

Five instruments.
Five ways of saying:
I am going to look at you carefully.
I am going to ask you what you see.
I am going to find out
what you're holding
by touching the surface
of what you'd rather keep closed.

This is called an examination.

This is called care.

Both of these are true.

The instruments know the difference
between them.

The body decides
whether it matters.
