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.
Unique Aberration-Free Optics: better vision for more patients
Bausch & Lomb SofPort®
The World's First Aberration-Free IOL
Aberration-freeAdvanced Optics IOLs have aspheric anterior and posterior surfaces. Their unique shape results in no aberration being introduced into the patient’s eye.
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.
Natural functionalityAdvanced Optics IOLs leave the eye with its natural positive aberration.
This allows for enhanced depth of field.2,3

Uniform power from centre to edgeAdvanced Optics IOLs are designed with no variation in power from the centre right to the periphery.
Independent of the eye’s optical alignment, they can provide predictable outcomes for all patients, including those with undetected zonular weaknesses or decentred pupils.

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.

Standard Spherical IOL Aspheric Aberration-Free IOL
Aberration-FreeBausch & Lomb's Advanced Optics IOLs have aspheric anterior and posterior surfaces that create no spherical aberration.
They are neutral to the cornea so are suitable for all patients regardless of corneal shape*.
Performance is unaffected by optical misalignment or pupil decentration.
Predictable, repeatable refractive outcomes means better vision for more patients.
Positivesphericalaberration
Negativesphericalaberration
Positive Spherical AberrationBiconvex spherical surfaces create positive spherical aberration (SA): peripheral rays come to a shorter focus than central rays.
Positive SA results in a loss of contrast sensitivity: pseudophakic patients with standard IOLs have more spherical aberration and less contrast sensitivity than phakic patients of the same age1.
Decreased Contrast Sensitivity
Convolved E & image simulating positive spherical aberration
Convolved E & image simulating coma higher order aberration
Negative Spherical AberrationModified prolate anterior surface creates negative SA designed to offset the positive SA of a typical cornea2.
All corneas are different, so will not suit all patients3,4.
Ocular misalignment may cause HOA such as coma, resulting in significant visual impairment5,6,7,8.

Constant power from centre to edge is important for good vision1
It does not worsen visual defects resulting from imperfect shape and alignment of the eye
Particularly important when the IOL is not perfectly positioned
Even a lens perfectly centred in the capsular bag is likely to be misaligned with the visual axis
Without uniform power from centre to edge any misalignment may result in visual impairment
Most important in low light situations
The difference uniform power can makePhotographic images simulate vision in mesopic conditions with a 4 mm pupil and a lens 0.5 mm off visual axis. The photo on the right depicts the loss of vision quality that can occur with spherical aberration.

The Natural Phakic EyeNot all corneas are the same shape and, therefore, introduce different amounts of spherical aberration into the eye.
The optics of the phakic eye are not perfectly aligned.

All axes in the eye are not perfectly aligned and no two eyes are the same shape so you need IOLs that work with imperfect conditions.

Natural Functionality
Enhanced depth of fieldThe phakic eye has a natural degree of positive spherical aberration (+SA)
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
Enhanced visual comfort
Thanks to improved Anti-Glare Technology from Bausch & Lomb, reflected glare is reduced in two ways:
The lens material has a moderate refractive index3
The anterior surface has a steeper curvature similar to the natural lens3,4
The retina reflects light forward. IOLs create glare by allowing light reflections from the anterior surface back towards the retina.3
Corneal Peripheral rays
Corneal Medium rays
Corneal Central rays
In intermediate vision more distant objects are seen through central corneal rays whereas closer objects are seen through peripheral corneal rays.
