Have 63 yr. old male who had cataract surgery 6 mos. ago. He has worn verticle prism of 9dn od and 9 up os. We have made plano rx lenses with the prism in frames for polycarbonate polarized sunglasses with a 5 base curve. He complains of less clarity in the right lens as worn. The lenses have been checked for waves, abberation, etc. with no findings. His IOLs are the bifocal type where the right has an add of 4 and the left an add of 3. I suspect the IOLs to be responsible for the variance in accuity but wonder if the prism applied may also create issues with polarization. Are there other factors that may play a part in his problem?
Any input would be helpful. Thanks, Bob Wheeler, ABO-AC
