Soft lens in -6.25 power?

I've found out that most manufacturers don't make quarter diopter
increments after -6.00, but I need that quarter difference between
eyes (and I need the -6.25 in my r. eye). I'm open to wearing whatever
soft lens works--doesn't have to be weekly disposables. I wonder if
there are companies that will make custom powers.

Problem is: I have a tiny scar on my sclera (r. eye) which becomes
irritated very easily by contacts. Not sure if it's due to lens edge
design or what. So my lens options are more limited. So far, I can
wear ProClears and Extreme H2O's in r. eye, but they don't come in
-6.25. I don't have astigmatism. My eye doctor gave me trial lenses of
Focus Monthly in -6.00 and -6.25, but after 3 hours my r. eye got
irritated, congested, etc. The l. eye could barely tolerate FM for 6-8
hrs.

I noticed that the 2 lens brands I CAN wear are both 14.2 mm diam and
the ones I CAN'T wear are 14.0 and 14.1 mm (Acuvue, Hydrogenic 60's,
Focus Monthly). Could the smaller diameter be causing the irritation?
(I'm thinking maybe the smaller lens hits the edge of the scar, and
the larger lens covers the edge of the scar). With the FM I had
continual "edge sensation" in both eyes after 3 hours. Do FM's just
have a bad edge design? What's their reputation?

My eye doctor is working with me on this, but I thought I'd post and
get some feedback. Seems like it's really hard to get information on
the www that compares contact lens design.

Thanks,

Thanks for the reply.
I really DO need that slight difference of .25 diopter. I used to wear
both the same power and never liked it. While there is very little
difference in the office as you say, there is greater diff outside in
bright light. This is especialy true for me because my r. eye pupil
does not constrict as much as the l. eye pupil. So my left eye really
gets too clear and then just dominates.

I'm really hoping to find just one -6.25 that actually fits my r. eye!
