This is a long and complicated subject. The majority of post-RK patients I
have worked with have required custom-designed rigid gas-permeable lenses
to achieve the best vision. These lenses are able to correct not only the
farsightedness, but also the irregular astigmatism that often occurs as a
result of RK. These lenses and the time it takes to fit them will require
an investment of time and money.
On the other hand, some post-RK patients have done quite well in soft
lenses. You have a borderline amount of astigmatism for a conventional
soft lens, and you may need a toric lens to correct the astigmatism. You
would need to go for a trial fitting first to find out. Also, post-RK
corneas are more sensitive to oxygen deprivation and very easily grow blood
vessels that follow the RK incisions. And, since you like to sleep in your
lenses, they should have the highest possible oxygen permeability. The
soft lenses that fit this criterion are the Focus Night and Day, the Acuvue
Advance(not FDA approved for overnight wear), and Purevision(available
outside the U.S. at present). None of these lenses are available in toric
versions for the correction of astigmatism.
You cannot purchase lenses on the internet without a prescription, and you
cannot get a prescription without seeing a doctor for a trial fitting. As
I said, this is a complicated subject.
