Purevision toric contact lenses are currently the only toric contact
lens that is approved for 30-day wear. The lens is made from the
revolutionary Silicone Hydrogel material Balafilcon A used in the
Purevision spherical lens and uses the patented AerGel process.
The Purevision toric promises to provide the same continuous wear
properties and benefits of the spherical PureVision lens in an
innovative toric (astigmatism correcting) lens.
The Purevision Toric lens is a good choice for patients who need
the highest level of oxygen transmission, such as those who have had
previous problems due to insufficient oxygen on the cornea. The lenses
are intended for patients with low-to-moderate cylinder powers, but may
help those with low amounts of astigmatism who are currently wearing
regular spherical contact lenses (uncorrected astigmatism).
In clinical testing, Bausch and Lomb reported that the lens compared
very well to their popular Soflens 66 Toric contact lens in that they
had similar stability compared to that lens. Also, 82% of patients
reportedly preferred PureVision Toric to their previous contact lens
for consistently sharp vision. They also reported that the lens causes
no significant corneal swelling during overnight wear. This is great
news for patients needing a correction for astigmatism. Now they can
have the freedom to wear contacts daily or, subject to their doctor's
approval, for up to 30 days of continuous wear.
