Is the iStent safe for MRI scans?2020-05-13T17:31:36+00:00

Yes, it is safe for MRI scanners 

Do I need to stay in hospital?2020-05-13T17:32:02+00:00

No, all surgeries are day cases 

Are there any contraindications for the use of iStent?2020-05-13T17:32:30+00:00

The iStent is not recommended for certain types of glaucoma. I will discuss your suitability at the preoperative visit. 

A friend of mine had another MIGS, why don’t you offer other MIGS ?2020-05-13T17:33:09+00:00

Every glaucoma surgeon is using the devices that work better for them. I chose to use the iStent after careful consideration and I am getting very good results with it. However, I will consider another device, if it proves to be safe and effective. 

What drops do I need after surgery?2020-05-13T17:33:35+00:00

Same drops as after cataract surgery, I may also adjust your glaucoma medication. 

Will the iStent cure my glaucoma?2020-05-13T17:34:04+00:00

No, the Istent will not cure your glaucomaHowever, it may prevent your glaucoma from getting worse by lowering your eye pressure. The iStent can also reduce your use of eye drops for glaucoma. 

Will the iStent improve my vision ?2020-05-13T17:34:32+00:00

Unfortunately not. Neither will it bring back any lost vision. 

What are the risks of iStent?2020-05-13T17:35:05+00:00

In general, the iStent implantation does not increase the risk of a cataract operation. There is a small risk of the eye becoming inflamed and developing an infection, so you will be given anti-inflammatory and antibiotic eye drops to use after the operation to prevent this. A very small amount of bleeding inside the eye might occur during the operation but this resolves within a few days. In about 20%, the iStent doesn’t work. 

What are the risks of not having the procedure?2020-05-13T17:35:28+00:00

If the eye pressure remains elevated despite medical therapy then there is a risk that your vision will deteriorate.  

Are there any alternatives?2020-05-13T17:35:52+00:00

Alternatives include the standard glaucoma surgery (trabeculectomy), but this carries more risk than the iStent procedure. 

PreserFlow Pre-operative Assessment2023-12-02T17:32:24+00:00

This procedure will only be carried out with your consent and you will be asked to sign a consent form when you are put on the waiting list.

You will have a preoperative assessment to determine if you are suitable for the procedure and if any further investigations will be required.
