Astigmatism
Patients with astigmatism usually have an irregularly shaped
cornea, called corneal astigmatism. Another type of astigmatism
is called lenticular astigmatism. This is the result of an
irregularly shaped lens, which is located behind the cornea.
Either kind of astigmatism can usually be corrected with eyeglasses,
contact lenses or refractive surgery.
However, many patients with astigmatism, wearing soft toric
lenses experience changing or unstable vision due to the toric
lens rotation, a common problem often associated with toric
contact lenses used to help correct astigmatism. The variable
vision can occur anytime and is often more noticeable in lower
levels of illumination, such as driving at night.
The SynergEyes® A lens was designed to provide
an astigmatic correction without the contact lens rotation.
Patients with
astigmatism can now enjoy clear vision from contact lenses
without the worry of unpredictable toric lens rotation. The
rigid center of the SynergEyes® A hybrid contact
lens uses the natural tear layer behind the lens to correct
corneal astigmatism
providing crisp, reliable and stable vision, and delivering
consistently clear vision – blink after blink.
Your eye care professional will be able to tell if the SynergEyes® A lens
is the right lens for the correction of your astigmatism.
