Can anyone let me know why a patient can't see well out of her new bifocal. her rx is a od +13.25 os +12.00-1.00x178 with prism in both eyes as 1base out. she never use to have prism and her old rx was +14.25(od) +13.50-1.00x178(os) with no prism. Is it the prism which she needs to get use to? Doctor is on vacation and I want to know what it could be or what I could tel her. Any suggestions?
Also we changed lens material from poly to aspheric ultra lite 1.56. Do this have anything to do with it too???
thanks
