PRESBYOND Laser Blended VisionA clear choice for presbyopic patients
PRESBYOND® Laser Blended Vision from Carl Zeiss is an advanced method for treating patients with age-related loss of accommodation, also known as presbyopia. It offers the opportunity to achieve freedom from glasses by combining the simplicity and accuracy of corneal refractive surgery with the benefits of increased depth of field in retaining visual quality. As a surgical solution based on the naturally occurring spherical aberrations of the eye, PRESBYOND Laser Blended Vision extends the scope of customized ablation beyond the limits of conventional monovision laser methods in several ways.
Whether for its customized treatment profiles, its visual acuity at all distances, its indications range or its immediate impact, PRESBYOND Laser Blended Vision is a clear treatment choice for the fast growing demographic of presbyopic patients.

Conventional monovision
With conventional monovision treatment
methods (both surgical and contact lens),
the dominant eye is corrected for distance
vision to almost plano. The non-dominant
eye, on the other hand, is corrected for
near vision, usually to be myopic up to
-3.0 D. Accommodation is thereby often
diminished. The method aims to achieve
optimal vision at distance and near range.
Following the procedure, the brain must
contend with two separate images with
different levels of correction.
According to scientific studies, only about
60 % of patients are able to successfully
merge the two images to experience
sharp binocular vision at near and distance
range.1 Patients that tolerate the method
are left with an uncorrected, compromised
gap in the intermediate range, the so-
called Blur Zone. In addition to the fuzzy
image, it can also cause other side effects
such as reduced contrast sensitivity and
stereoacuity. Also, it often takes patients a
long time to get used to merging the two
images into one picture.
Conventional monovision is a correction
method with compromises. For a number
of patients, it is not a suitable option.
PRESBYOND Laser Blended Vision
As a new, physiologically optimized laser
treatment method for presbyopic patients,
PRESBYOND Laser Blended Vision
represents the next stage in eye care
excellence. Similar to conventional
monovision, the dominant eye is corrected
for distance vision to almost plano, whereas
the non-dominant eye is corrected to be
slightly myopic for near vision to -1.5 D.
This micro-monovision strategy is further
enhanced by a decisive difference: an
increase in the depth of field of each eye
using a wavefront-optimized ablation
profile to create a continuous refractive
power gradient for the whole optical zone
of the cornea. PRESBYOND Laser Blended
Vision is an absolutely individualized
treatment plan based on preoperative
spherical aberrations and the functional
age of the eye. As a result, a customized
fusion of the two images for near and
distance vision is created for each patient –
the so-called Blend Zone.
Although similar to conventional monovision laser treatments in terms of the workflow, PRESBYOND® Laser Blended Vision takes customized vision correction a step beyond, particularly with respect to the outcomes.
Next-level vision correctionbeyond conventional monovision
The unique Blend Zone
Essentially, the Blend Zone makes it easier for the brain to merge the images of both
eyes, thereby achieving true binocular vision. This is a significant advantage over
conventional monovision. In addition to excellent near and far vision, PRESBYOND
Laser Blended Vision patients also experience very good visual acuity and contrast
sensitivity in the intermediate range. They adapt faster and most are delighted about
not having to wear glasses anymore. Not surprisingly, PRESBYOND Laser Blended
Vision is tolerated by a high number of patients – up to 97 %.1

Individualized ablations
PRESBYOND Laser Blended Vision is a truly customized
approach for treating presbyopic patients. It incorporates
preoperative wavefront data to fine-tune the depth of
field for each eye individually. The functional age of the
eye is also factored in. In result, a personalized ablation
profile is created for optimized target refraction. The mono-
vision component can be pre-adjusted for the patient’s
tolerance level. Also, different optical zone sizes can be
selected to account for the patient’s pupil size.
Ideal for a growing demographic
As an optimized laser method for age-related loss of
accommodation, PRESBYOND Laser Blended Vision is
ideally suited for serving the needs of patients 40–60 years
of age – a fast-growing demographic group interested in
sophisticated options. It is also one of the least invasive
methods for addressing presbyopia.
Familiar procedure
Following the same workflow as established LASIK
procedures, PRESBYOND Laser Blended Vision combines the
convenient binocular treatment planning of the CRS-Master®
with the proven comfort and workflow of the MEL® 80
excimer laser from Carl Zeiss.
Customized
Generally speaking, conventional monovision methods utilize standard ablation profiles. In the case of PRESBYOND® Laser Blended Vision, they are customized for each eye individually because of the increased depth of field.
PRESBYOND Laser Blended Vision provides the most natural form of presbyopic
correction, including 97 % of all refractive errors with preservation of contrast
sensitivity, night vision and stereoacuity; it is easily enhanced, adjusted and even
reversed, if needed. It’s the Olympic Gold medalist in presbyopic surgery.

All distances
Strictly in terms of the visual outcomes, PRESBYOND® Laser Blended Vision transcends conventional monovision methods by offering clear sight at all distances: near, intermediate and far. Better yet, virtually all patients are freed from the need to wear reading glasses.1-4, 6
Outstanding visual acuity
By customizing each eye individually, PRESBYOND Laser
Blended Vision provides excellent visual acuity for near and
distance vision. Unlike conventional monovision methods,
PRESBYOND Laser Blended Vision also offers good inter-
mediate vision in the Blend Zone. According to clinical
studies, there is virtually no loss of contrast sensitivity and
stereoacuity is maintained. Also, side effects such as
multiple images in one eye are almost eliminated.
An all-natural approach
PRESBYOND Laser Blended Vision is a physiological solution
and a true binocular method for treating presbyopic patients.
Wide indication range
PRESBYOND Laser Blended Vision is a proven and effective
method for treating indications ranging from -8.0 D to
+2.0 D, including emmetropic and astigmatic presbyopic
patients (up to 2.0 cyl).
I have been impressed by the very high patient tolerance rate for
PRESBYOND Laser Blended Vision which is much higher than what we see
for conventional monovision methods.

Immediate
What also clearly sets PRESBYOND® Laser Blended Vision apart from other laser techniques is the immediate positive impact it offers patients and refractive surgeons alike – visually for the former, economically for the latter.1–4
Appropriate for most patients
A key advantage of PRESBYOND Laser Blended Vision is
that it is proven to be tolerated by more patients than
conventional monovision. It is effective for treating up to
97 %1 of all presbyopia-related forms of impairment as
compared to only 59–67 % for conventional monovision.
Even presbyopic patients with emmetropia and astigmatism
can be treated. In fact, it has the potential to achieve a far
greater success rate than any comparable treatment.1,5
A competitive edge
PRESBYOND Laser Blended Vision allows refractive practices
already using a MEL® 80 excimer laser and CRS-Master®
from Carl Zeiss to significantly expand their LASIK repertoire
and increase the patient base. For most patients, a positive
effect is that they can read without glasses the very same
day. As such, PRESBYOND Laser Blended Vision offers a
decisive competitive advantage over LASIK practices only
specializing in monovision treatment methods.
ZEISS Laser Blended Vision is the answer to the missing platform in LASIK refractive
surgery for myopic, hyperopic and even emmetropic patients.
