Sorryi have not had cataract surgery
A tube shunt using an Ahmed valve or Baerveldt tube is where a tube is placed in the anterior chamber of the eye (space between the iris and cornea) to slowly siphon out fluid from that part of the eye into a controlled reservoir underneath the conjunctiva where it slowly dissipates away
The principles are not unlike those of a trabeculectomy, but its indications and utilty can be different in some cases than a trabeculectomy. The risks are also very similar. Pain, infection, bleeding, risk of the tube closing off, risk of the pressure going to low, risk of the tube extruding through the sclera, conjunctiva or cornea, risk of the pressure not being low enough, need for further surgery. Does this make sense?
Is it a painful procedure and what are the long ter prospects of its success
Also, since you have not had cataract surgery, this is an additonal possible risk, that you have cataract formation from this. Does all this make sense? Do you have any additonal questions that I haven't addressed yet?
Is it a good long term solution and treatment for glaucoma
Yes, it can be an excellent long-term solution; people who have this surgery can have consistent pressure lowering effects for many years to come.
Do you have any other concerns about this topic that I haven't addressed?
Do you often need drops in conjundtion with this surgery
Yes, usually a steroid drop is used, as well as a dilating drop (sometimes). This is on top of whatever glaucoma drops your surgeon wants you to be on still.
Are these long trm or just post procedure
Thank you I cant think of any more Questions at the moment
