cataract surgery on left eye early september 2009. successful. 2 weeks later, i experienced lightheadedness, headaches, increased sed rate. had cat scan, brain mri, temporal artery biopsies.. all were fine. sent to rhuematologist; she could find no problem. i feel like my right eye, which is scheduled for cataract surgery in november is working independently. it feels heavy and blank, but i can see out of it. it was probably 20/50, but after surgery on left eye, my right eye seems blurry. opthamologist says all is ok. ive been on prednisone since lightheadedness began.. being slowly decreased. lightheadedness and headaches are improving after approximately 1 month.. could my symptoms be a cause of the eyes working independently?
