Hoyalux FD
Hi Win C,
5 out of 10 is 50% of your patients having issues with FD. That is a very high percentage. I find it that when i have problems with patients adapting to new lens designs, first thing i do is check the measurements on the patients previous pair of frames. this will allow you to know what your patient has previously acustomed to.
In most cases labs have very high quality control procedures and would not allow 5 out of 10 over or under corrected lens pass QC.
panto tilt and "bow" of the frame are very important factors to take into account when a patient is complaining about blurred vision in the distance.
"And when I ask the patient to tilt his head down until he thinks the distance vision is clear, it's about 3 mm (sometimes more) above the fitting cross."
this tells me that the prescription is correct on the lens(3mm above the fitting cross would be the distance prescription checking zone meaning full distance rx would be measured on the vert here). When your patient tilts his head down he/she is essentially creating a tilt on the lense and his/her eyeball rotating upwards. This is a simulation of panto tilt.
I have had great feed back regarding the FD. Patients love this new pal design. I havent had any problems with it at all!
tell me what you think?
cheers
