Hi everyone, I was wondering if you could help me out with this one.
We have a 72 years old patient that has worn progressives in the past (in the 80īs) but now was wearing trifocals and wanted to try progressives again. On 08.02.2011 we put him in a Rodenstock PureLife and he came back one week later complaining about poor near vision.This is his rx:
OD -0.50 -1.25 x 006
OS +0.25 +0.25 x 170 add +2.75
He told us that he had to turn his head to his left if he wanted to read comfortably with his right eye, otherwise the left half of the line was blurred. He inquired if we had fitted his lenses inhouse and even accused us of fitting them poorly, he told us they were off center. We checked the rx, pd, heights, panto and vertex distance and everything was fine. To make a long story short, he walked away.
He came back yesterday (09.29.2011) with a new pair of Varilux Comfort Poly that he bought elsewhere "because we had poorly fitted his previous lenses inhouse and they were off center" and guess what...
"He has to turn his head to his left if he wants to read comfortably with his right eye"
I checked his new glasses and they are right. I thought that maybe he is experiencing some horizontal prismatic imbalance when he reaches the reading zone.The OD is a minus so there is base in, base out for the plus OS. He has no problem when looking at the distance.
Whatīs your opinion and what should I do next? I would really appreciate your input.
Thanks!
