Went through my medical records from when I was 7.
At that time I had a cycloplegic refraction of
-1.0 Dsph -2.5Dcyl
-1.0 Dsph -3.5Dcyl
but my first glasses prescription had weaker cyl by 1D:
-1.0 Dsph -1.5Dcyl
-1.0 Dsph -2.5Dcyl
I wonder what could be the reason for this and what could be the long term consequences of undercorrecting astigmatism in a child?
