OA-2000
• Dear Kathrin,
My great pleasure to have you in our department with the OA2000.
So far, the device has been quite impressive, especially by its
speed and user-friendliness.
• Dear Kathrin,
The machine looks great. Measurements look quite the same
compared to the Aladdin, but I already had some eyes where
the Aladdin was not able to measure the axial length and the
OA-2000 was.
• Hello Kathrin First demo = sold unit!!!!
• Hi Kathrin,
I wanted to let you know, I've just done the first OA-2000
demonstration at the customer site in Turku univ. hospital,
where they also have the TMS-5. This was the first time I've
seen the end users literally dance out of joy! They loved it!

Key Selling Points
•Easy to use  operation & calculation
•Patient comfort  very fast measurement
& dimmed fixation light
•Accuracy and reliability  K readings from
Topography & All in one measurement
•Internal Database storage & DICOM
compatibility (available soon)
•IOL calculation  classic & modern
New Technology
Fourier Domain Light Source
•Using a Fourier
Domain Light
Source  high
sensitivity and
high SN ratio! 
much higher
scanning rate of
1.000 scans/sec vs
Time Domain of
only 10 scans/sec
New Technology
Axial length by B-scanning
Black part is lens
opacity.
It’s impossible to
measure by
conventional A-scan.
•B-scanning can
avoid lens opacity
•With B-scanning it
is possible to find
highest echo with
dense cataract eye
and it makes
measurement
possibility higher.
OA-2000 can measure by Bscan through clear part of lens.
New Technology
Axial Length by B-scanning
•Advantage of B-Scan
Example of axial length measurement by B-scanning.
Lens opacity obstructs the light and it looks
black.
Conventional optical biometer can not
measure this opacity at the center of lens.

New Technology
Axial Length by B-Scanning
B-scanning enables to find the path without opacity
and measure axial length with opacity lens.
Axial length can be measured through
small opacity (black part)

IOL calculation CLASSIC
IOL calculation CLASSIC
What is needed for a standard (classic) IOL
calculation?
• K readings
• Axial length
• ACD
• A-constant of the IOL!
IOL calculation CLASSIC
FAQ
A-constant:
• Which one is the correct
one?
• Adjusted A-constant for
OA-2000?
• Nominal A-constant?
• A-constant for different
formulas
• Which formula do I use for
which eye?
• ULIB Database? 
yes, if you use IOL Master
settings!
• Under negotiations with
Dr. Giacomo Savini
• Only for Ultrasound mode,
possible with OA-2000
• Yes, see ULIB
• Long eyes, short eyes,
Lasik eyes

FAQ
• Our OA-2000 is
prepared to enter all
different A-constants
for different formulas
• Please enter data
manually for different
fitting formulas

(no need to fill out
everything)
IOL calculation CLASSIC
FAQ
• Setting for using the
ULIB A-constants:
• K readings used from
2,5mm diameter
• Fitting formula must be
immersion mode (in all
new machines from now
on this is DEFAULT
setting, former OA
models were with fitting
formula contact!)
IOL calculation CLASSIC
Accurate
K readings
are so
important!
IOL calculation CLASSIC
Topographic information about K readings
Accuracy
• “3.0mm” is used as “Contact
mode” of ultrasound
measurement. “3.0mm” is
standard value when Kerato
is measured.
• “2.5mm” is used as
“immersion mode” of
ultrasound measurement.
“2.5mm” is same as “IOL
master”.
• “2.0mm” is useful
for measurement of
“irregular astigmatism
eyes”.
Kerato manual mode
Importance
• Why is it so important?
Sometimes you have
difficult patients with
difficult corneas
(keratoplastic etc)  in
such cases we
recommend the manual
Kerato setting! All other
measurements will be
done fully automatic
afterwards!

OKULIX
Why cutting the
potential of getting a
perfect IOL?
No need for asking the
question: Which
formula? Which Aconstant? Input of IOL
Data….ALL is already
installed in Okulix, even
toric lenses can be
easily calculated!
IOL Calculation MODERN
OKULIX
OKULIX safes time
Overcome Gaussian optics by numerical ray tracing
Personal statistics are not necessary
Reduction of miscalculation in case of
– Extremely long eyes
– Normal eyes
– Extremely short eyes
– Extreme curvature of cornea
• OKULIX is the only means in special cases
– After refractive laser surgery
– Toric IOL
– Phakic IOL
• Knowledge of the differences of the formulae and IOLs is not
necessary, the biometry could be delegated.

“State of the Art” Combination
OA-2000 & TMS-5
What can be better than combining two fantastic
machines to one PERFECT State of the Art device??
“State of the Art” Combination
OA-2000 & TMS-5
Why would you do this?
...because we can use the full power of Okulix software
taking front and backside curvature of the cornea
into consideration, therefore getting the ultimate
results in IOL Outcome!
What you need and how to do it?
...connect both machines to the same PC and use the
TMS-5 software in between. Take OA-2000
measurement and export it to this PC, take TMS-5
measurement and then use the VA-200 software 

Tomey Japan is continuously working to improve the
software even better, updating the OA is incredibly
easy and therefore we can only say:
TRUST the machine and GO FOR IT!!
Thank you very much for your high attention!
