Usually dysphotopsia symptoms improve greatly over time. Also you said you could read some as long at the light was bright - so there is at least some reasonable news here. I think it is totally reasonable for you to get a second opinion from another board-certified ophthalmologist in your area before your proceed with the yag, since you have reservations and are not totally confident in your surgeon.

I am not a doctor. Only a patient such as yourself. It is absolutely possible and advisable to seek a second opinion from a qualified surgeon especially before proceeding with further procedures such as YAG. You should always take the time to explore your options. ]
Good luck.
