I Am Looking For An Ophthalmologist For Cataract Surgery; I

I am looking for an ophthalmologist for cataract surgery; I have been examined and told that my cornea is pitted and scarred. I am a 71 year old female. I was recently diagnosed with breast cancer; I had surgery in March. The Tamoxifen that was prescribed seems to have exacerbated my vision/cataracts. My breast surgery was botched; this makes me very concerned about choosing a physician for eye surgery ... the surgery must go right; my vision hangs in the balance.
