Proven ZEISS Optic for aspheric preloaded IOLs
CT ASPHINA 613P (1)
- CT ASPHINA 613P is the same IOL model as CT
ASPHINA 603P (formerly known as XL Stabi ZO).
The only difference is the new design of the
preloaded cassette that is used exclusively with
SkyJet Advanced. - CT ASPHINA 604P is the same IOL model as the
formerly known Invent ZO.

2Zeissgeist in optical design
3Zeissgeist in optical design
- Advancing aspherics
- Carl Zeiss has a long history of experience in
developing aspheric lens concepts and solutions
for a variety of products and systems. - In fact, with many of its innovative
developments, ZEISS has managed to literally
capture the zeitgeist(1) of a technological era. - Consider such milestones as the first aspheres to
correct astigmatisms (1899) or a novel retrofocus
type aspheric lens for high-speed motion picture
cameras (1975), to name but two. - Consider such ZEISS milestones as
Photo camera objective with aspheric lens
Microscope with aspheric optic design
Aspheric optic for binoculars
(1) Spirit of the times
4Zeissgeist in optical design
- New generation of aspheric IOLs
- For more than a century now, Carl Zeiss has
defined high-level quality, unparalleled optical
expertise and outstanding innovation in optical
technology. - For the first time, ZEISS has applied this proven
technology to a new generation of aspheric IOLs
used in cataract surgery. - Introducing the first members of the ZEISS Optic
aspheric IOL family the CT ASPHINA 613P and the
CT ASPHINA 604P.

6ZEISS in your eyes Precision of the designed
asphericity concept
- Precision of the ZO (600) asphericity concept
- In developing its aspheric lens concept, ZEISS
combined the best of both worlds the advantages
of negative spherical aberrations IOLs and
aberration-neutral IOLs. - The unique ZO / 600 asphericity concept is
designed to - correct a part of the spherical aberrations of
the pseudophakic eye - be less sensitive to decentration and tilt
- improve the retinal image quality of patients
vs. spherical IOL - maintain depth of field vs. spherical IOL
- offer maximum visual performance for the largest
range of patients - be used in routine and be adapted for the vast
majority of patients
7ZEISS in your eyes A recognized eye model
- The benchmark among eye models
- The advanced ZEISS aspheric lens is patterned
after the - Liou Brennan (LBE) eye model, widely regarded
as the most anatomically accurate eye model in
ophthalmology today. - LBE places the young, phakic human eye into an
optical, - physiological and realistic environment, using,
among other things, the physiological off-axis of
the pupil in nasal and the tilt of the
visual/optical axis as its basis. - Similarly, the ZEISS Optic / 600 concept closely
mimics the anatomical and optical imaging
properties of the young, natural human eye.
The ZO / 600 lens design is based on the widely
recognized Liou and Brennan (LBE) eye model

- A full range of clinically proven advantages for
surgeons and patients - The unique and well-known ZEISS aspheric Optic /
600 concept combines the advantages of negative
spherical aberration IOLs and aberration neutral
IOLs correcting a part of spherical aberrations,
maintaining depth of field, and optimizing visual
performance for the largest range of patients.
The ZO (600) IOLs offer a full range of
clinically proven advantages for surgeons and
patients. - Confidence in a well-known ZEISS aspheric optic
- Proven efficacy of the asphericity optic concept
(A) - Proven to provide the same amount of SA as the
natural young crystalline lens (B) - Proven better visual performance vs. spherical
IOL (B) - Proven to maintain depth of field vs. spherical
IOL(B) - Proven precise, reproducible and stable outcomes
(AB) - For routine use and adaptation to the vast
majority of patients (AB)
10Proven optical excellence of the ZO (600) IOLs
Maximum visual performance for the largest range
of patients
The optic of the ZO (600) IOLs closely mimics the
anatomical and optical properties of young phakic
eyes for the largest range of spatial
frequencies. Eyes implanted with ZEISS Optic /
600 asphericity concept IOLs show a similar
amount of spherical aberrations to the phakic
eyes from the control group (Graph 1) (A).
Graph 1 MTF curve of the ZO (600) IOL group is
similar to the MTF curve of the young phakic eyes
control group, showing that the IOL mimics the SA
of the natural crystalline lens in a stable way
(12 month post-op.). (OPD-Scan measurement)
11Proven optical excellence of the ZO (600) IOLs
Maintained depth of field
The development of the optical concept of the ZO
(600) IOLs is based on the Liou Brennan eye
model, the most anatomically accurate eye model,
allowing the IOLs to have low sensitivity to tilt
decentration (B). The concept also keeps a
small amount of spherical aberrations,
maintaining depth of field in implanted eyes
equivalent to spherical IOL implanted eyes (Graph
2) (B).
Graph 2 Depth of field of eyes implanted with ZO
(600) IOLs is comparable to the depth of field of
eyes implanted with spherical IOLs. At 1 year
follow-up.

The 2 pictures below clearly show the impact of
the depth of field on the quality of the image,
its really an advantage for patients that ZO
(600) IOLs maintain depth of field.

13Proven optical excellence of the ZO (600) IOLs
Superior optical performance compared to a
spherical IOL
Due to their innovative aspheric concept, ZO
(600) IOLs outperform spherical IOLs by improving
the quality of the image (Graph 3) (B).

21SkyJet Advanced- the new, smaller incision
injector only for CT ASPHINA 613P
- I am a long time user of the ZEISS aspheric
3-haptic preloaded IOLs with the SkyJet injector
system as they offer precise, stable and
efficient outcomes for routine cataract surgery.
I was waiting for a new, smaller incision
injector and now its done with SkyJet Advanced
so the combination is even more attractive - Dr. Gilles DENIS, MD, France
- Much smaller incision
- SkyJet Advanced allows for an ergonomic, reliable
and predictable implantation of the CT ASPHINA
613P through a much smaller incision. The
diameter of the SkyJet Advanced injection tip is
significantly reduced compared to the regular
SkyJet, making the incision size required to
inject the IOL much smaller.
Reduced surface of the SkyJet Advanced tip
22SkyJet Advanced- the new, smaller incision
injector only for CT ASPHINA 613P
Predictable, controlled and safe IOL delivery The
SkyJet Advanced further improves reproducibility
of injection due to a new plunger and a new
design of the preloaded cassette. The precise
folding of the IOL, its centered, straight and
controlled delivery into the capsular bag, makes
the injection very safe, predictable and
comfortable.
Take advantage of the new and impressive SkyJet
Advanced to maximize efficiency, safety and
reproducibility by implanting the proven CT
ASPHINA 613P through a much smaller incision for
improved outcomes, optimized surgical workflow
and happier patients.
23SkyJet Advanced, the new smaller incision
injector only for CT ASPHINA 613P
Minimal incision, maximum performance
Due to a thinner injection tip, a new design of
preloaded cassette and a new plunger, this unique
premium combination of a proven innovative
aspheric optic preloaded IOL and a high-tech
injector allows for an ergonomic, reliable and
reproducible implantation of CT ASPHINA 613P,
through a significantly reduced incision size.
