Step 1: Diagnosis

To be considered as a possible candidate for the treatment, you must first be examined to confirm that you have End-Stage AMD.

This will involve a thorough medical eye examination and a review of your medical history, including any conditions that may make the procedure difficult for you or increase the likelihood of complications. Mr Antcliff will explain the benefits and risks of the CentraSight treatment programme and answer any questions you may have.

Step 2: Assessment and Preparation

CentraSight Team Members: Low Vision Optometrist, Low Vision Rehabilitation Officer.

The preparation stage includes a low vision consultation performed by a low vision optometrist and an interview by phone with the low vision rehabilitation officer.

The assessment and preparation step includes testing your vision using external telescope simulators. The results of these tests can help give you and your CentraSight Team a good idea of what your vision may be like after the telescope implantation surgery and if the effect of the magnification in one eye will be useful to you. Low vision specialists will also talk to you about how your new vision status may affect your everyday life and how following a visual training/rehabilitation programme after surgery will help you reach your vision goals.

Step 3: Surgery

The telescope implantation surgical procedure is performed on only one eye. It involves removing the eye’s natural lens and replacing it with the tiny telescope implant. The surgical procedure is relatively short (1-1.5 hours). You won’t have to stay in hospital overnight and will return home the same day.

The telescope is virtually unnoticeable to others because it is implanted totally inside the eye, and mostly covered by the coloured portion of the eye (iris).

What to Expect with the Surgical Procedure

Before the Surgery

Before the surgery, Mr Antcliff will take your medical history and check the health of both of your eyes. You will need to arrange for transportation to and from your surgery appointment.

Day of Surgery

The procedure is performed on an outpatient basis and generally takes 1-1.5 hours.

The surgery involves several steps:

  • Your eye will be numbed at the beginning of the procedure so you will not feel any pain
  • Special eye drops will be administered to temporarily enlarge your pupil
  • Your eye’s natural lens will be removed
  • The telescope implant will be placed in the same position where the natural lens was located
  • The surgical incision will be stitched closed

If the telescope cannot be implanted during surgery, a standard intraocular lens (IOL) will be implanted, as in any procedure for cataract removal.

After the Surgery

After surgery, you will have follow-up visits. You will have to take eye drops for several weeks.

You should expect a gradual improvement in your vision of the treated eye to occur over a period of time, ranging from weeks to months.

Step 4: Visual Rehabilitation

CentraSight Team Members: Low Vision Optometrist, Low Vision Rehabilitation Officer.

After you have recovered from surgery, specially trained low vision optometrists and rehabilitation officers will work with you to prescribe spectacles and complete your rehabilitation to help you adapt and learn how to use your new vision in daily life. They will work with you on an individualised plan over several visits to reach your personal goals.

What are the Benefits of the Telescope Implant?

The effectiveness of the telescope implant has been demonstrated in American Food and Drug Administration (FDA) approved studies.

In results from a survey in the FDA clinical trial, patients who received the telescope implant generally reported that they were less dependent on others, less frustrated and worried about their vision, less limited in their ability to see, and better able to visit others and recognise facial expressions/reactions. Overall, the survey findings showed patients had a clinically important improvement in quality of life and that nine out of ten patients with the telescope implant improved vision by at least two lines on the eye chart. 1.

What are the Risks of the Telescope Implant?

As with any medical intervention, potential risks and complications exist with the telescope implant. These will be discussed at your assessment appointment.
