iStent is a treatment for glaucoma.

What does iStent involve?

Step 1: Your in-depth consultation

Following a detailed assessment, your Consultant Ophthalmic Surgeon will discuss the best course of treatment of primary open angle glaucoma for you. The consultant will be the same person who carries out your glaucoma surgery and your checks at follow-up appointments.

Step 2: The iStent procedure

iStent is a microscopic trabecular bypass implant. This means a tube implant inserted into the natural drainage system channel of the eye to increase the drainage of fluid from the eye and reduce eye pressure on average by 20%* or more. It can also reduce the use of eye drops for glaucoma. 7 out of 10* patients have been able to stop using eye drops completely following this procedure and the remainder have been able to reduce them.

iStent will not reverse any damage already caused by glaucoma or bring back any lost vision.

It can be successfully used in combination with cataract surgery, and in eyes that have already had cataract surgery.

The iStent is made from non-magnetic titanium (the same material used for replacing heart valves, so it won’t be rejected by the body or cause an allergic reaction). It will not set off airport scanners or cause problems if you need an MRI scan.

Step 3: Rest and recovery

Following your glaucoma surgery, you will be taken to our recovery suite to rest before being given details of any eye drops required and returning home. Your consultant will also provide you with antibiotics to use following treatment.

Step 4: Your aftercare

Your consultant will see you for a follow-up consultation to check on your progress, assess the results and answer any questions you may have about treatment for glaucoma. You will be provided with an emergency contact number so that if you do experience any unexpected symptoms, you can contact us.

Am I suitable for the iStent implant?

Often used as a treatment for glaucoma, the iStent is a tiny titanium tube which is inserted into the eye to help lower eye pressure. It can also help reduce the need for eye drops – 7 out of 10 patients report not needing them at all following the procedure. The iStent is a popular option of treatment thanks to its compatibility with cataract surgery.

To assess if you are eligible for the iStent implant, you will undergo a full consultation with one of our ophthalmic surgeons. Should you choose to go ahead with the treatment, the same ophthalmic surgeon will also carry out the procedure, as well as guide you through the aftercare checks. We understand how important every individual’s eye health is to them, which is why we are with you every step of the way.

During your consultation, our eye health specialists will follow general guidelines to see if you are suitable for the iStent implant including identifying if:

  • You have mild to moderate open-angle glaucoma
  • You are currently taking one or more medications to lower your eye pressure
  • You are already scheduled for cataract surgery
  • You are generally healthy enough to undergo minimally invasive surgery

The iStent treatment is not recommended for advanced glaucoma. If this affects you, our ophthalmic surgeons will talk you through the best alternative options for your eye health needs. At Optegra, we know that everybody is different which is why we assess every patient individually so you can be confident you will be receiving the right treatments options for you.

iStent implant customer reviews

The iStent implant is a relatively straightforward, minimally invasive procedure that our expert surgeons carry out on a regular basis.

We are committed to ensuring our customers receive world-class service far beyond their treatment. While you are being looked after by Optegra, you will first have an in-depth consultation with one of our ophthalmic surgeons to discuss the procedure and prepare you for the journey ahead. We always ensure that it is this consultant who will also carry out your surgery and your aftercare check-ups, as we find our patients feel more at ease when they are dealing with a familiar face all the way through the process.

Our dedication to post-surgery aftercare is second to none. You will meet with your surgeon for a follow-up assessment, as well as be provided with an emergency contact number in case you experience any unexpected symptoms in the following weeks.

It is this personal touch that has afforded us the honour of most-trusted eye health specialists, as voted by our patients. But don’t just take our word for it, take a look at the reviews from our iStent patients.
