Econopred is prednisolone acetate, a steroid, which is used
postoperatively to decrease inflammation and to help slow healing
after a trab (you don't want the flap to heal down or it will stop the
outflow of fluid, thus raising the eye pressure).  The reason your doc
may have increased it to a more frequent dosing regimen may be that
you had a little more inflammation than expected when your eye was
seen in the office after surgery.
