Hi. I'm online and happy to answer your question today.
That sounds like it could be due to your cataract, however, It would be very unusual for things to change so quickly from just a cataract.
It is also possible that you are having problems with your retina, in the central area called the macula. I know you just went to the eye doctor last month, but I think it would be best to see the ophthalmologist again in the very near future just to make find out what is causing your new vision loss.
The doctor will not only be able to compare your current vision to what it was on the last visit, but will also be able to dilate your eyes and check out your retina.
Does this make sense to you?
And, now, the obligatory word from our sponsors: :o)
