VARIABLE VISION? PROBLEM SOLVED.
Because the power in a toric lens is not equal in all meridians, rotational stability is a critical factor in visual
acuity. Early toric designs did not always optimize stability, resulting in variable vision. But today’s toric lens
designs have been refined to provide very stable, exceptionally clear vision.
Consider a lens like the Bausch & Lomb PureVision® Toric lens. The patented Lo-Torque® design provides
exceptional rotational stability. In a 2006 study, this newer design was preferred by eye care professionals
across a variety of metrics when compared to alternative lens designs, such as the dual thin zone design.1

In a clinical study of over 100 ACUVUE Advance for Astigmatism wearers who were successfully refit in
PureVision Toric Lenses, eye care professionals reported:
• Patients who were wearing ACUVUE Advance for
Astigmatism lenses previously had full lens
centration only 78% of the time2
• Only 75% of patients wearing ACUVUE Advance for
Astigmatism lenses previously had 20/20 or better
visual acuity2
• Once refit in PureVision Toric lenses, 91% of
these patients experienced full lens centration2
• After being refit into PureVision Toric lenses, 86%
of patients achieved 20/20 or better visual acuity2

Outstanding convenience
Better compliance
Compliance with daily disposable lenses is
higher than with both monthly and 2-week
lenses.13
For younger patients this is especially
important, as compliance with cleaning
regimens and replacement schedules is
generally quite low.14
Better comfort
As with most patients, comfort is a key
success factor for first-time wearers. Studies
suggest that up to 82% of all patients prefer
the comfort of daily disposable lenses.15

A well-designed toric lens will also achieve full centration, which provides better optical quality. Centration is
the main determinant of high contrast vision performance, playing an important role in aligning the lens
optics with the visual axis enhancing optical quality.

1. Outstanding convenience
The convenience of daily disposable lenses

The Bausch & Lomb PureVision Toric lens is also designed to help reduce the amount of positive spherical
aberration by adjusting the shape factor of the anterior surface across a range of powers. The aspheric optics
combined with all of the other sophisticated design characteristics help PureVision Toric lenses deliver
improved vision quality in a variety of settings.
It’s not surprising to find that the design features of PureVision Toric contact lenses can deliver exceptional
vision to astigmatic patients even versus spherical lenses. Specifically, in a clinical evaluation of astigmatic
patients conducted comparing the PureVision Toric lens to wearers refit from their previous lenses, 89% of
the patients achieved 20/20 vision or better when wearing the PureVision Toric lens.3 Only 35% had
achieved 20/20 with spherical lenses.
Don’t let patients settle for a less than optimal vision correction and for astigmatic patients that means giving
them a toric lens. Educate your patients and offer them a proven toric lens design – PureVision Toric. They’ll
be glad you did.
All day comfort
Bausch & Lomb’s SofLens® daily
disposable lenses offer ComfortMoist™
Technology – a combination of a thin lens
design and unique packaging solution that
works with tears and envelops lenses in a
cushion of moisture – works to further
enhance all-day comfort.

PROMOTE PATIENT COMPLIANCE
>Daily Disposable Lenses continued
from page 1
Today’s lens wearers expect more from their lenses than ever before. In fact, the majority of wearers
(54%) report needing to wear their lenses for more than 15 hours a day.4 As a result, many patients will
stretch their lenses to accommodate the longer wear times – a behavior that’s the leading cause of lens
complications.5
This makes SofLens® daily disposables an
excellent option for younger wearers who
may be wearing lenses for longer hours
during the day.
To help reduce non-compliance with replacement schedules, doctors could switch 2-week lens wearers
to a monthly modality. Why? Studies suggest:
Exceptional visual quality
• As few as 32% of patients wearing 2-week lenses are compliant with their replacement schedules 6
• As many as 82% of patients wearing monthly lenses are compliant with their replacement schedules6

Younger wearers tend to have a lifestyle
that may put them in more low-light
situations. A lens that features High
Definition optics to help reduce spherical
aberration and improve contrast – like the
SofLens daily disposable lens – can help
give these patients crisp, clear vision in
such conditions.
A recent study shows that the visual
quality of SofLens daily disposable lenses
were preferred to the leading spherical
design, especially in low-lighting.

Long wear times demand long lasting comfort. If your patients are wearing their lenses for a month, help
them be more successful by fitting them in a lens that’s built to last for a month: the Bausch & Lomb
PureVision® contact lenses.
PureVision lenses have a unique Performa™ surface – keeping lenses smooth, clean and wettable, so they
enhance comfort while resisting protein and lipid deposits.9
Give your patients a lens with long-lasting comfort, and promote compliance at the same time. Recommend Bausch & Lomb PureVision lenses.

Daily disposables are affordable
While the advantages of daily disposable
lenses are manifold, some practitioners
hesitate to recommend them based on
perceived high cost. But the reality is,
with the availability of rebates and no
cleaning solutions to buy, patients can
get the benefits of daily disposables for
around $1 a day.17
It’s no wonder parents consider this
option for their kids, with so many
practical benefits for new wearers. It is
clear that SofLens daily disposable lenses
can be an important alternative for
practitioners who strive to deliver the
best corrective option for each and every
patient.
DON’T LET TORIC LENSES’ HIGHER COST BE A BARRIER
Recent studies show that the large majority (90%) of current contact lens patients are interested in
discussing innovations in contact lenses with their practitioner and have an increased appreciation for
eye care professionals who inform them about new technology.10
A common assumption that leads to masking low-cylinder astigmatic patients is that the higher cost
will deter them from wanting to be fit with toric lenses. But it’s the eye care practitioner’s responsibility
to give patients every opportunity to take advantage of the newest technologies, explain the options,
and provide your professional recommendation so patients can make informed decisions.
Presuming certain options are too expensive for patients could undermine not only the application of
your clinical expertise but also your patient’s comprehensive understanding. The patient will decide
which option is right for them, including their desire to pay a premium for advanced technology that
provides exceptionally crisp vision and healthy eyes.
Today’s toric lens wearers can experience exceptional rotational stability and are now looking for
additional features to further enhance their experience: excellent vision, longer wear times, better end
of day comfort and white, healthy eyes.
Even if patients seem satisfied with their current lenses, be proactive by offering new
technologies to them. Studies suggest they will most likely be glad you did. The added
benefit for you is that you’ll have distinguished your practice, which can strengthen
patient loyalty.

PureVision® Toric and Multi-Focal silicone hydrogel line of lenses, patients overwhelmingly preferred the
new lenses.11

Patients’ comments after being refit into the newer technology included12:
“I like the comfort and vision better.”
“My vision is much crisper with these lenses.”
“My eyes are whiter.”
Across many variables, patients are clearly having very positive experiences when upgrading to the
Bausch & Lomb PureVision Toric lenses.

patients wanted to achieve better visual outcomes and were willing to pay the incremental costs.
