A BRIEF HISTORY OF MAGNIFICATION IN
MEDICINE
T
he principle of magni
f
cation is fundamentally
based on light refraction; by placing an object
between 1 and 2 focal lengths from the retina, a
magnifying lens can enlarge the object
s appearance while
maintaining resolution.
1
Archimedes is credited with the
invention of the
burning glass,
a series of lenses used to
focus the sun
s rays on enemy ships, causing them to catch
f
re. The Roman Claudius Ptolemaeus described and
calculated light refraction by water, whereas Seneca and
the English philosopher Roger Bacon reported the
magni
f
cation of text by looking through a water-
f
lled
sphere.
2
Ibn al-Haytham furthered the understanding of
human vision with descriptions of ocular anatomy,
function, and visual principles in his
Opticae Thesaurus
,
3
leading to the introduction of eyeglasses in the late
13th century by Italian monks who could grind glass.

As
early as the 1500s, surgical technique began focusing on
f
ner work. When Andreas Vesalius
f
rst described
the abdominal aortic aneurysm in the Netherlands
4
during the 16th century, European battle
f
eld surgeons
treated vascular injuries through ligature and vascular
suturing, albeit rarely with success and always without
magni
f
cation.
5
The
f
rst compound microscopes are attributed to the
Dutch spectacle makers Hans Jansen, Zacharias Jansen,
and Hans Lippershey, who around 1590 discovered that
objects could be magni
f
ed using elongated telescope
tubes.
2
Soon after, Galileo studied small objects using a
similarly adapted telescope. He was a member of the
Accademia dei Lincei
in Rome, whose members
f
rst
coined the term
microscopium.
2
In England, Robert
Hooke used a compound microscope to discover and
describe the cell, whereas the Italian optician Giuseppe
Campani examined wounds and scars.
3,6
In 1677, a
medical student, Johann Ham, discovered spermatozoa
in the ejaculate of a patient with gonorrhea. He reported
his
f
ndings to the Dutch scientist Antonie van Leeu-
wenhoek, who performed extensive studies on seminal
uid, reporting his results in
>
150 letters to the Royal
Society in London.
7
As pathology became increasingly important to surgical
practice during the late 19th century, surgeons used
magni
f
cation to facilitate tissue dissection. Charles Louis
Chevalier, a French optician,
f
rst constructed a loupe
that could be used during surgery, magnifying objects
10 fold at a 7-cm distance. In 1886, Carl Wilhelm
von Zehender, a German ophthalmologist, modi
f
ed a
zoologic binocular and placed it on a tripod, creating a
prototype surgical microscope and the forerunner of the
slit-lamp.
2
Although von Zehender
s binocular was too
big for use in the operating room, in 1912, the Zeiss
Company introduced a lighter binocular set of operating
loupes worn like glasses.
2
In 1923, the Leitz Company
introduced a prismatic loupe, which permitted beam
splitting, allowing assistants to share the same view as the
surgeon,
2
facilitating teaching of surgical technique and
photographic image capture. In the spring of 1921, the
otorhinolaryngologist Carl Olof Nylen performed the
f
rst
ear operation using a modi
f
ed monocular microscope in
Stockholm, solidifying his place in history as the
f
rst true
microsurgeon.
8
In 1946, the American ophthalmologist
Richard Perritt borrowed a binocular operative micro-
scope from his otorhinolaryngologist colleague, G. E.
Shambaugh, for use during an eye operation. Subse-
quently, other specialties, including neurosurgery and
plastic surgery adopted microsurgical techniques during
the 1960s.

MICROSURGERY AND UROLOGY
In May 1974, Sherman Silber, an American urologist,
met Earl Owen, a plastic surgeon from Melbourne,
Australia, at a Royal College of Surgeons conference in
Sydney.
9
Owen was a world renowned microsurgeon
having founded the International Microsurgical Society
in 1969,
10
and by most accounts had performed the
f
rst
vasovasostomy in Australia in 1971.
10
At the time of
meeting Silber, Owen was working in organ trans-
plantation. A pioneer in his own right, Silber had devised
a microsurgical method in 1973 to facilitate his studies
with rat kidney transplantation using eyeglasses with

f
cation, mosquito forceps

led to 1 mm thickness,
and 9-0 suture.
