Hi everyone! I have been working with a patient with a prescription of
o.d:-5.50-1.50X035
o.s:-5.00-1.00X150 1D BU prism
+2.50 Add ou
Pt purchased lenses only and last prescription was aprox. the same. However, when pt received the new lenses, she could not see out of distance clearly. The prescription checked out okay on the lensometer,Pd was correct(Monocular PD's were 31.5/32.0)and same as last pair, we put her in same progressive, lens type and index with same seg placement of 25.(Pt is in Hi index 1.6 Plastic Adaptar). I then took her to dr. who checked refraction and it was the same as he had prescribed. He seemed to think it was all in the pt's head and told me to add paniscopic tilt. Which I did and seemed to helpa little but pt called back after a few days saying it is still not better. So I remembed reading about the base curves of lenses and checked them. Her first pair was 3 in both and her new ones were 2.25 in both. Since this was the only thing different, I told pt we would reorder wtih a different base curve of lens. With her prescription would this be the reason of her altered vision in distance only? Should I check base curve on all prescriptions or just certain cases?
