During the surgery
of cataract removal, the following instruments
and machine make it all possible. Below there
is an image and brief description of what
the instrument does.
Eye
Measurer
The device used to measure the length of
the patient’s eye uses ten million
sound waves a second. The sound waves travel
at 3500 miles per hour.
The
Microscope
The microscope used during the
operation is manufactured by Zeiss.
Zeiss is the foremost manufacturer
of optical equipment in the world.
The
Phakoemulsify
The machine used to break up the cataract
(phakoemulsify) is controlled by a microprocessor.
The vacuum levels and energy used are
kept with very stringent limits.
Phaco Tip
The tip of the probe used to break up the
cataract vibrates to and fro at 40,000 times
a second. At the end of each stroke it experiences
a G force of 250,000 and in that instant weighs
several tonnes. It is made of titanium because
steel would disintegrate under such conditions.
It is thrown away after each case.
