Am I a Candidate?

In general, to be considered a potential candidate for the telescope implant an ophthalmologist must first confirm that you:

  • Have irreversible, End-Stage AMD resulting from either dry or wet AMD.
  • Have not had cataract surgery in the eye in which the telescope will be implanted.
  • Meet age, vision, and cornea health requirements. You must be at least 75 years of age.

After the ophthalmologist confirms that you are a potential candidate, your vision will be tested using an external telescope simulator. The results of the test and visual training/rehabilitation evaluation visits will help you and your ophthalmologist decide if you are likely to benefit from the CentraSight treatment program. If so, the tests will also help you and your ophthalmologist discuss which eye should be treated and what your vision may be like after the treatment.

The CentraSight treatment program involves four steps that start with diagnosis and continue after surgery.

  • Step 1: Diagnosis
  • Step 2: Candidate Screening
  • Step 3: Surgical Procedure
  • Step 4: Learning to Use Your New Vision

A member of your CentraSight team is involved at each step of the treatment. All CentraSight team members are highly qualified professionals, with special training in the CentraSight treatment program and the telescope implant technology. The following pages explain what you can expect at each step of the program.

The telescope implant is not a cure that "sees" for you. For the telescope implant to work for you, you will need to work with low vision specialists as well as practice on your own at home.

Realistic Goals:

  • Recognizing faces of family and friends
  • Watching television
  • Reading
  • Various hobbies like painting, knitting or gardening

Unrealistic Goals:

  • Driving
  • Seeing a golf ball in flight
  • Playing tennis
  • Never having to use a magnifying glass again

Visual goals can be assessed with an external telescope simulation during pre-surgery screening visits.

Your ophthalmologist will describe the risks and benefits of the telescope implant to you, including the risks of surgery.


Step 1: Diagnosis

CentraSight Team Member: Retina Specialist (Ophthalmologist)

To be considered as a possible candidate for the treatment, you must first be examined by a retina specialist 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. Your retina specialist will explain the benefits and risks of the CentraSight treatment program and answer any questions you may have.

Step 2: Candidate Screening

CentraSight Team Members: Retina Specialist, Low Vision Optometrist, Low Vision Occupational Therapist

The screening includes several appointments and a low vision evaluation performed by a low vision optometrist.

The candidate screening 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 providers will also talk to you about how your new vision status may affect your everyday life and how following a visual training/rehabilitation program after surgery will help you reach your vision goals.

Step 3: Surgical Procedure

CentraSight Team Member: Cornea/Cataract Surgeon (Ophthalmologist)

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) and is performed by a specially trained ophthalmologist. You won't have to stay in a hospital and will return home the same day.

Surgical Procedure

The tiny telescope is implanted in the place of the eye’s lens to help improve vision in patients with End-Stage AMD, the leading cause of blindness.

During the Procedure Complete

CentraSight’s implantable telescope technology reduces the impact of the central vision blind spot due to End-Stage AMD. The telescope implant projects the objects the patient is looking at onto the healthy area of the light-sensing retina not degenerated by the disease.

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

What to Expect with the Surgical Procedure

Before the Surgery

Before the surgery, your surgeon will take your medical history and check the health of both of your eyes. You should let your surgeon know if you take any medication or have any allergies. Be sure to discuss all your questions with your surgeon before scheduling your surgery. 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.
  • The surgeon will remove your eye's natural lens.
  • The telescope implant will be placed in the same position where the natural lens was located.
  • The surgical incision will be sutured closed.

If your surgeon is unable to implant the telescope during surgery, he or she will implant a standard intraocular lens (IOL), as in any procedure for cataract removal.

After the Surgery

After surgery, you will have follow-up visits with your surgeon. 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.

If you are found to be a candidate, your surgeon will provide you more detailed information about the procedure and potential risks.

Step 4: Learning To Use Your New Vision

CentraSight Team Members: Low Vision Optometrist, Low Vision Occupational Therapist

After you have recovered from surgery, specially trained low vision optometrists and occupational therapists will work with you to prescribe eyeglasses 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 individualized plan over several weeks to reach your personal goals.

What are the Benefits of the Telescope Implant?

The effectiveness of the telescope implant has been demonstrated in 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 with others and recognize facial expressions/reactions. Overall, the survey findings showed patients had a clinically important improvement in quality of life.1

An FDA study found 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.

The most common risks of the telescope surgery include inflammatory deposits on the device and increased pressure in the eye. Significant adverse events include corneal swelling, corneal transplant, and decrease in visual acuity. There is a risk that having the telescope implantation surgery could worsen your vision rather than improve it. Individual results may vary. You should talk to your doctor about these and other potential risks to find out if the telescope implant is right for you.
