It would be helpful to have some information such as distance and near uncorrected vision and the corrected distance and near vision. If you are on target (astigmatism less than 0.50 D and near plano) your distance and near vision should be good. If on target you have another problem most likely a macular problem. About 95% of patient on target and without macular problems will do well. It may take up to six months. About 5% will not adapt the the halos and glare. Bilateral IOL patients do better. More patients will have problem is not on target.
I would suggest a second opinion.

I can see entirely your reservations about the multifocal lens, that level of night vision disturbance is quite extreme I think. What I find worrying is the blurred vision when reading especially as it has been tidied up with a laser. My own experience is a week and a half ago I had a ?re-zoom multifocal lens implanted in my left eye. The following day, despite a little discomfort and slight on and off blurring I could read the smallest writing given to me and it has continued to improve. My right eye was done 2 days ago and the reading vision was not as quite as good but usable. I dont expect it to improve drastically and expect to have it improved with a laser in the next 6-12 months. I can manage to then and the eye will be fully healed. I am disappointed it was not as good as the first eye, but my long sight is perfect, bar a little post op blurring at times, I have halos still around lights at night, but have been able to drive safely short distances - I expect these to improve. I think my experience is far more the norm than yours .If I was you I would get a second opinion before proceeding as it is over 2 months since your surgery and you are having significant difficulties.
