Hi all,
I have a patient here fitted with a new pair of Hoya FD with prescription of:
OD: -4.00/-1.25 X180
OS: -1.75/-1.00 X180
ADD of +2.25
He had been using Hoya GP previously with prescription of:
OD: -3.50/-1.25 X180
OS: -2.25/-1.00 X180
ADD of +1.75
He had been complaining that distance at vision with the new FD was not good, and felt the field of vision was narrow (more distortions seen at the side). he mentioned near vision as fair,but not as good as GP. Overall, he was quite unsatisfied with the FD.
So my question is ,what may have contributed to this patient's problem? I was thinking about the difference hard (GP) and soft (FD) design of the PALs that could have caused his problems. Maybe can someone here shed some light to me, and we can discuss this problem together..
Thanks...
