Improved PureVision® Lenses - Same Exceptional Visual Performance with Enhanced Comfort
Improved design delivers enhanced comfort. Plus, a New 8.3 Base Curve
|
The new and improved design with smoother anterior surface of PureVision® spherical lenses deliver enhanced comfort – for both 8.6 and 8.3 base curve. Also, 28% lower modulus.

The same superior visual performance you’ve come to expect:
PureVision® lenses deliver better vision when it matters most.
- Aspheric anterior surface successfully reduces spherical aberration.2
- Patient-preferred for reducing halos at night.3
Compared to their previous lenses, PureVision lens wearers
report:3
- Better overall vision - 81%
- Better low-light vision - 70%
- Better vision while driving at night - 69%
New 8.3 base curve expands fitting options
1 Twenty-four subjects completed a
one-day dispensing evaluation comparing PureVision test lenses manufactured
with the prior process to the previous PureVision lens. The test lenses
exhibited statistically significant better comfort and forced-choice preference
compared to the PureVision control lenses.
2 Twenty subjects were dilated to achieve a minimum of 6 mm pupil diameter.
Baseline spherical aberration was measured using a Zywave™ aberrometer.
PureVision and Night & Day (-1.00D and-5.00D)contact lenses were inserted
into one eye in random order. The measurement of spherical aberration was
repeated with the contact lens in place. A second cohort of 20 subjects
compared PureVision and ACUVUE Advance (-1.00D and -5.00D) contact lenses using
the same protocol. PureVision lens spherical aberration measures were averaged
between the two evaluations. A third cohort of 20 subjects compared ACUVUE
Oasys and O2Optix (-1.00D and -5.00D) contact lenses using the same
protocol.

Brief summary of intended use: The Bausch & Lomb PureVision Visibility
Tinted Contact Lenses are indicated for daily wear or extended wear for up to
30 nights between removals. Warnings: The risk of microbial keratitis has been
shown to be greater among users of extended wear contact lenses than among
users of daily wear contact lenses. The long-term risk of microbial keratitis
has not been determined for this lens. Post-marketing studies are in progress.
Precautions: Some patients will not be able to tolerate continuous wear even if
able to tolerate the same or another lens on a daily wear basis. Some patients
who are able to tolerate continuous wear will not be able to wear their lenses
continuously for 30 nights. Patients should be carefully evaluated for
continuous wear prior to prescription and dispensing, and eye care
professionals should conduct early and frequent follow-up examination to
determine ocular response to continuous wear. Side effects: During the one-year
US study of the PureVision lens (spherical), 2.9% of the 820 eyes that were fit
with the PureVision lens in one eye experienced infiltrative keratitis. Other
less serious side effects were mild forms of dryness, discomfort, and burning
and stinging. Contraindications: The lens should not be used in the presence of
any inflammation, infection, disease or injury in or around the eye or eyelids
that interferes with contact lens wear. The lenses should not be used by
individuals who have a systemic disease or an allergic condition that might
interfere with contact lens wear.
