I went to an eye doctor to get my 6 year old examined. He gave an astigmatism prescription. He used an old autorefractor and then followed up with manual refraction to come up with final prescription. I went for a second opinion. The second doctor used a newer autorefractor but did no manual refraction.
The prescriptions are very different in one eye. The first dr gave OD as sp: -0.5 cy: -2.25 ax: 15 OS as sp -0.25 cy: -1.5 ax 155. The second dr gave sp: -0.5 cy: -2.25 ax: 10 OS as sp -0.5 cy: -2.25 ax 170
Which would be a more accurate prescription.
