IMT is a treatment for end-stage AMD.
What does IMT (implantable miniature telescope) involve?
The IMT (implantable miniature telescope) can improve vision and quality of life for people who have lost central vision in both eyes because of end-stage AMD. Manufactured by VisionCare Ophthalmic Technologies, it is the first FDA-approved surgical device for AMD and enlarges what you’re looking at by nearly three times its normal size. The IMT is part of the CentraSight® treatment programme, which has been designed to help patients see the things that are important to them, regain independence, and re-engage in everyday activities.
The CentraSight® treatment programme involves four steps that start with diagnosis and continue after surgery.
Step 1: Your in-depth consultation
You will have a detailed assessment by your Consultant Ophthalmic Surgeon, a trained low vision optometrist and a rehabilitation specialist to see whether you will be suitable for the IMT. The same consultant will carry out your procedure and the team will work with you at follow-up appointments.
Step 2: Before your implantable miniature telescope procedure
When you arrive at the Optegra eye hospital, your consultant and clinical team will be waiting to welcome you and help you to feel relaxed. Anaesthetic eye drops and a local anaesthetic will be administered: once they’ve taken effect, your consultant will begin the treatment.
Step 3: During your implantable miniature telescope procedure
The implantable miniature telescope is smaller than a pea. It is implanted into just one eye during a surgical procedure similar to cataract surgery where the natural lens of the eye is removed and replaced with an artificial lens. The eye implanted with the telescope provides magnified central vision, while the other eye provides peripheral vision.
The skin around your eye will be thoroughly cleansed and a sterile cover placed over your eye and face, which will be lifted off your mouth so you can breathe easily. Your eyelids will be gently held open, although they will feel closed.
The surgery involves removing the eye’s natural lens and replacing it with the tiny telescope implant, which is virtually unnoticeable. The procedure generally takes 1 - 1.5 hours.
You will see little of what is happening during surgery, but we will explain what we are doing as the operation goes along and the theatre staff will help you relax.
Step 4: Rest and recovery
Afterwards, you will be taken to our recovery suite to rest before returning home. Patients will need standard glasses to focus after surgery and to take eye drops for several weeks. It could be some weeks before the best possible glasses are prescribed.
Step 5: 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. You will be provided with an emergency contact number so that if you do experience any unexpected symptoms, you can contact us.
Specially trained low vision optometrists and rehabilitation specialists will work with you to help you learn how to use your new vision in daily life.
