The difference between the two prescriptions is largely accounted for
"convention" in writing prescriptions. One is written in "minus
cylinder." The other, in "plus cylinder."
The latter prescription -- written in the same 'convention' as the
former -- works out to:
RE: -1.00 +.75 x111
LE: -1.50 +1.50 x85
The difference, then, is far less than it first appears. She's
slightly myopic with a bit of astigmatism.
Have they actually /diagnosed/ your DD for "accommodative excess??"
It is an actual clinical condition* that has diagnostic criteria and
for which various treatments DO exist.
It's also a good idea to have a pediatric /strabismus/ ophthalmologist
"intervene" while your DD is young. There is a physiologic link
between accommodation (the eye focusing) and convergence (the eye
turning inward to view near objects). If she truly has accommodative
issues, then a strabismus ophthalmologist (or binocular function
optometrist) is the one to monitor and advise.
The eye drops you referred to are virtually always preserved with a
chemical agent that's /really/ bad for the eyes ... over time. If
this were a temporary use thing, then I might consider it.
If it were "during school" as in ... years ... I would strongly
recommend avoiding it, in lieu of other treatments (glasses and/or
vision therapy ARE options).
Reading glasses or bifocals ARE a treatment for accommodative excess,
but I'd be sure that a 'thorough' dilation (perhaps using cyclogyl, or
stronger agent) is/was performed to be sure.
Young accommodative mechanisms are strong. They need to know exactly
how much accommodative spasm this young one might be hiding before
prescribing.
A really competent strabismus doc will be able to balance all the
factors and prescribe the right glasses, if necessary.
