Dear bob160,
I would recommend that you seek the care of your eyeMD immediately and have your eye examined especially the retina. Without a further history and examination, the etiology is not known. By the drops you are using, I assume you may have swelling of the area of your finest vision, known as cystoid macular edema.

First of all, you could simply need to wear reading glasses. If your uncorrected distance vision is good then by definition you will need reading glasses usually to some degree since the implant is monofocal. You could also have cystoid macular edema, corneal edema, astigmatism, epiretinal membrane, or other causes of decreased vision. Have a talk with your surgeon and ask why your reading vision is not better.
