I think SofLens66 Toric can be worn on a monthly basis.  It is recommended
to be a 2-week lens but in my experience most patients can wear it longer.
The wearing time that you get from a contact lens is very
individual-specific.  A few patients can dirty-up their lenses quite quickly
and won't get as much wear out of them (e.g. patients with environmental
allergy problems).  Also, the chances of getting contact lens complications
such as GPC increases with longer wearing times.  In conclusion-- if you
have been successfully wearing your lenses for about a month, then I don't
see why you should change to a 2-week disposal cycle if you aren't having
any problems.

At the present time, O2Optix lenses are not available in your prescription.
The toric versions, especially in plus powers, have not been released by
CIBA yet.

Likewise for Focus Daily Toric.  While toric versions are available (x90 and
x180 only) for minus powers, they are not available for plus powers which is
what you need.  I do not know whether CIBA plans to make such a lens in the
future.  I would doubt it.  These would not be high-volume sellers.

You might want to consider trying the new Acuvue Advance Toric lenses which
have just been released.  They are available in your prescription.  They are
made of a silicon hydrogel material and are oxygen permeable.  This makes
them healthier for your eyes in general and may make them more comfortable
for you.  They are made by Vistakon.  Talk to your eye doctor about them.
Maybe you can get a trial pair and try them out.

Your current brand, SL66 Toric, is quite a good lens.  Currently it's my
"go-to" brand of toric disposables so you are already in a good place as is!
