I had an epiretinal membrane removed from one eye on June 2. The
surgery went well without complications. After the operation the
surgeon put me on the following drops:

June 3 (saw surgeon)
    Started Isopto Atropine (relaxes the eye) one drop a day.
    Started Tobradex 4 drops a day (prevents irritation and
    infections).
June 10 (saw surgeon). I was not told my eye pressure was high.
    Continued Isopto Atropine one drop a day.
    Started Cosopt twice a day (decreases eye pressure).
    Decreased Tobradex 3 drops a day
July 11 (saw surgeon)
    Stoped Isopto Atropine.
    Continued Cosopt twice a day.
    Decreased Tobradex to 2 drops a day.
September 20 (saw surgeon)
    My eye pressure was 30. The surgeon said this was a side
    effect of the Tobradex
    Continued Cosopt twice a day.
    Decreased Tobradex 1 drop a day.
    Started Alphagan drops, twice a day (decreases the eye
    pressure).
October 5
    Stoped Tobradex.
    Continued  Cosopt and Alphagan.
I will see the surgeon in a few days.

My vision improved after the surgery although still changes a bit
about every two weeks.

My questions are:

Was it too long to use Tobradex for 14 weeks?
If my eye pressure was at 30 for 2 to 10 weeks is it likely that this
affected my optic nerve?

Thank you,
Carlos
