The World's First Aberration-Free IOL

Unique Aberration-Free Optics:
better vision for more patients
The aberrations present in the eye differ from person to
person. That’s why Bausch & Lomb has created the world’s
first aspheric IOLs with aberration neutrality and uniform
power, offering unique benefits independent of the
patient’s profile.

Aberration-Free IOL
Rocha prospective comparative study concludes1
The aspheric IOL SofPort® A0 showed significantly
less spherical aberration and HOA when compared
to the spherical IOL analyzed in this study without
compromising depth of focus.
The SofPort® A0 group also presented better contrast
sensitivity under mesopic and mesopic with glare
conditions.
"
Aberration-free
Advanced Optics IOLs have aspheric anterior and posterior surfaces.
Their unique shape results in no aberration being introduced into
the patient’s eye.
Uniform power from
centre to edge
Advanced Optics IOLs are designed with
no variation in power from the centre right
to the periphery.
Natural functionality
Advanced Optics IOLs leave the eye with its
natural positive aberration.
This allows for enhanced depth of field.2,3

Independent of the corneal shape, they
are suitable for all patients*, including
those who have previously received LASIK
treatment, who have keratoconus or any
other pre-existing corneal aberration.
Independent of the eye’s optical alignment,
they can provide predictable outcomes for
all patients, including those with undetected
zonular weaknesses or decentred pupils.

Modified prolate anterior surface creates negative SA designed to

Aberration-Free
Bausch & Lomb's Advanced Optics IOLs have
aspheric anterior and posterior surfaces that
create no spherical aberration.
Positive SA results in a loss of contrast sensitivity: pseudophakic patients
with standard IOLs have more spherical aberration andPositive
less contrast
sensitivity than phakic patients of the same age1.

Natural Functionality
Bausch & Lomb
SofPort®
The World's First
Aberration-Free IOL
Enhanced visual comfort
Enhanced depth of field
The phakic eye has a natural degree of
positive spherical aberration (+SA)
The retina reflects light forward.
IOLs create glare by allowing light
reflections from the anterior surface
back towards the retina.3
Aberration-free Advanced Optics IOLs leave
the pseudophakic eye with its natural +SA
This allows for greater depth of field1,2
Theoretically, a pseudophakic eye with
0.27µm of +SA will have about 0.5d
of additional pseudo-accommodation
compared to a pseudophakic eye
with no +SA
In general, more +SA means greater depth
of field, however too much +SA reduces
overall quality of vision
Simulation of vision affected by glare
Corneal Peripheral rays
Thanks to improved Anti-Glare Technology
from Bausch & Lomb, reflected glare
is reduced in two ways:
Corneal Medium rays
The lens material has a moderate
refractive index3
Corneal Central rays
The anterior surface has a
steeper curvature similar to the
natural lens3,4
In intermediate vision more distant objects
are seen through central corneal rays
whereas closer objects are seen through
peripheral corneal rays.

The first Aspheric IOL with planar delivery implantation
The Bausch & Lomb SofPort® Advanced Optics Aspheric
Lens System provides the benefits of sterile, single-use
lens delivery with proprietary planar delivery.
Surgeons really appreciate the ease of handling our systems provide
during final placement of the IOL into the eye. Spring-loaded designs
provide control throughout the entire procedure allowing one-handed
delivery of the IOL directly into the capsular bag.
The SofPort® System is designed for direct
(planar) delivery of the IOL into the capsular
bag, minimizing tissue trauma and related
potential complications.
Stage 1
Load the lens case to the injector
Risk of cross contamination is eliminated
with the disposable inserter.
Self-guided loading
The Sofport® EZ-28 Injector System is loaded with little or
no manipulation of the IOL. Engineering design and highquality materials provide mechanical guiding for IOL right
through to the final injection position.
