Ahmed or Baerveldt drainage implant surgery Ahmed Implant surgery and Baerveldt Implant surgery are slightly different types of Glaucoma Drainage Devices, but have many similar aspects. Most of the answers to these common questions are the same for each type of surgery. Why do I need Glaucoma surgery?

Glaucoma is a progressive disease that causes damage to the optic nerve, which is responsible for our vision. We cannot cure glaucoma, but we can treat it and prevent vision loss in most cases if the eye pressure is kept within normal range. If your eye pressure is not low enough with eye drops or laser treatments, you will likely be offered surgery as the next step.

Ahmed or Baerveldt drainage implant surgery. Ahmed Implant surgery and Baerveldt Implant surgery are slightly different types of Glaucoma Drainage Devices, but have many similar aspects.

How do I prepare for Ahmed or Baerveldt implant surgery? If you have had a trabeculectomy that is no longer working to control the eye pressure, or if you have a difficult type of glaucoma such as Neovascular Glaucoma eg from Proliferative Diabetic Retinopathy or Uveitic Glaucoma, for which trabeculectomies do not work well in the first instance, then an Ahmed implant will help to control the pressure quicker and longer than a trabeculectomy.

Why am I being offered a Baerveldt Drainage implant surgery? A Baerveldt Implant is a larger drainage device than an Ahmed implant. In studies comparing an Ahmed and Baerveldt implant, the Baerveldt implant seems to provide a longer lasting pressure lowering effect.

However, the downside is that it can sometimes cause the eye pressure to become too low, which is also not healthy for the eye. Also, a Baerveldt implant does not have a built-in valve system like the Ahmed Implant, therefore it must be tied off with a dissolvable stitch so that it will not start working until the eye wound heals and the tie dissolves about weeks after the surgery.

If you need immediate eye pressure lowering, an Ahmed Implant may be a better choice. However, if your eye pressures can be controlled with eye drops and medications for a few more weeks depending on your response to medications and your eye nerve healtha Baerveldt usually provides better pressure lowering for a longer period of time with fewer additional medications and fewer surgical revisions.

Watery fluid from inside the eye drains through the tube and collects over the plate and just under the conjunctiva. This fluid collection may be visible as a slight bump over the plate, which is hidden by your eyelid. Eventually the fluid is absorbed.

You will not notice the fluid draining unless there is a leak, which usually goes away by itself, or may need to be stitched closed.

This extra drain in the eye makes the eye pressure lower. However, often it is still necessary to use glaucoma eye drops to get the pressure into an acceptable range.
