With Toric Contact Lenses
Toric Contact Lenses For Astigmatism
are available for a wide range of prescriptions. Toric contact
lenses come in soft lens, gas-permeable and disposable
What is Astigmatism? - Astigmatism is
the result of the optical surface of the human cornea, lens or
retina not being spherical (round). Looking at the illustration at
the right, you can see graphically how cornea astigmatism affects
the eye. Cornea astigmatism is by far the most common, although with
higher astigmatisms, a Bi-Toric lens can be made which entails
correction on both sides of the contact lens. There are many
disposable contact lenses available for smaller astigmatisms under
3.00 diopter. Custom made Toric lenses can be manufactured as high
as 12.00 diopters of astigmatism.
New BI-Toric Contact Lenses (For
Astigmatism) - are available for high astigmatic prescriptions.
These Toric contact lenses come in soft lens, gas-permeable
and disposable formats.
contact lenses are designed for the correction of astigmatism. Many
people refer to this condition as football shaped eyes. More
importantly it is a condition where the vertical power of the eye is
different from the horizontal position. A soft lens that is weighted
on the bottom and or top to control rotation can solve this
prescription by successfully holding the two different corrections
while your eye is moving. In the past only gas-permeable lenses
would correct this condition. But now the option of soft Toric
lenses makes it easier than ever.
Irregular and Oblique Astigmatism
- can sometimes be associated with Pellucid Marginal Degeneration (PMD).
Eyes with slight PMD can also
be corrected with soft Bi-Toric contact lenses. Results with a
properly fitted Bi-Toric soft lens can be just as clear as hard
lenses or gas permeable lenses. See
PMD for more info.
