Yes, because they have glaucoma over a longer period of time. I don't feel like I have something in my eye. That is usually because the eyes are dry, and with the bleb sticking up and causing more friction, the result is irritation.
Younger people heal better and blebs tend to last for a shorter period.
Otherwise, I would repeat the trabeculectomy. I had an MRI and it was negative. MRI stands for magnetic resonance imaging. I think they use MRI to see if a tumor is the cause. A laser will only work in the acute stage.
