Lenses
for Astigmatism
There
are now many types of lenses to correct asigmatism. From a vision
point of view gas-permeable lenses generally give the best vision
as the tears form a 'natural' lens behind the contact lens. This
tends to correct astigmatism. However, for astigmatism over 2 dioptres
a toric lens may be required. These lens vary in their complexity
and may take a longer time to acheive a good fit. This type of lens
is the cheapest type of lens to use, but the initial outlay is greater
reflecting the greater number of consultations that are required
and the the fact that lenses being more expensive to produce.
Many
types of soft lenses are now avaiable. These need to be stabilised,
to stop them rotating, and thicker zones or prism are incorporated
in the lens. Diferent makes may use different design features to
acheive stability and you may need to try several types before aceiving
the best result.
1-day
disposables are available for astigmatism, but with a limited power
range they are not suitable for everyone. Monthly disposables now
come in a large range of parameters and are generally the most economic
of the soft astigmatic lenses. For patients with higher prescrriptions
bespoke soft lenses are available.
Prices
for astigmatic lenses start from £65 for six months of disposable
lenses. We are always happy to advise on the best type of lens for
your eyes and will quote you beforehand as to to expected cost of
fitting the lenses.
