available in Orange County, the CentraSight™ treatment
program features the first ever telescope implant surgical treatment
for patients with End-Stage age-related macular degeneration
(AMD), the most advanced form of AMD and the leading cause of
blindness in older Americans. More than 15 million Americans
are affected by some form of AMD.
The telescope implant is integral to CentraSight,
a new patient care program. It is the only medical/surgical option
that improves visual acuity by reducing the impact of the central
vision blind spot caused by end-stage AMD.
Smaller than a pea,
the telescope implant uses micro-optical technology to magnify
images which would normally be seen in
one’s “straight ahead” or central, vision.
The images are projected onto the healthy portion of the retina
not affected by the disease, making it possible for patients
to see or discern the central vision object of interest.
Patients with end-stage AMD have a central blind spot. This
vision loss makes it difficult or impossible to see faces, read,
and perform everyday activities such as watching TV, preparing
meals, and self-care. The telescope implant has been demonstrated
in clinical trials to improve quality of life by improving patients’ vision
so they can see the things that are important to them, increase
their independence, and re-engage in everyday activities. It
also may help patients in social settings as it may allow them
to recognize faces and see the facial expressions of family and
The first Orange County CentraSight Patient Treatment
Program team includes physicians of the Gavin Herbert Eye Institute,
Kupperman, M.D., Ph.D
and Stephanie Lu, M.D., the retina
specialists who coordinate the treatment; Sumit “Sam” Garg,

College of Optometry, the low-vision specialists who coordinate
the post-surgical therapy for the patient.

What is AMD?
Age-related macular degeneration (AMD) is a disease of the retina.
End-Stage AMD is the most advanced form of the disease and the
leading cause of irreversible vision loss and legal blindness
in individuals over the age of 65.
In early, less advanced AMD,
visual symptoms are generally mild and may or may not impact
vision-related activities. However,
advanced stages of AMD can result in severe loss of sight in
the central part of vision. This is often referred to as a central
vision “blind spot.” This blind spot is different
than the visual disturbances experienced with cataracts (clouding
of the eye’s lens) and is not correctable by cataract surgery
or eyeglasses. Side vision, or peripheral vision, is not affected
by AMD, but is too low resolution to make up for lost central
vision. At this time, there is no cure for End-Stage AMD and
no way to reverse its effects.
What is CentraSight™ and
the Telescope Implant?
The CentraSight treatment program uses a tiny telescope, an FDA-approved
medical device, which is implanted inside the eye to improve
vision and quality of life for individuals affected by End-Stage
The telescope implant, about the size of a pea, is intended
to improve distance and near vision in people who have lost central
vision in both eyes because of End-Stage AMD. The telescope implant
is surgically placed inside one eye. The implanted eye provides
central vision; the other eye provides peripheral vision.
telescope implant is not a cure for End-Stage AMD. It will not
restore your vision to the level it was before you had AMD,
and it will not completely correct your vision loss. Patients
with this level of AMD have had to cease driving due to their
vision; after the telescope procedure, although near and distance
vision may improve, driving will not be possible because the
implant does not restore normal vision.
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
Are no longer a candidate for drug treatment
of your AMD
Have not had cataract surgery in the eye in which
the telescope will be implanted
Meet age, vision, and cornea
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.
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.

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.
Recognizing faces of family and friends
Various hobbies like painting, knitting or gardening
Seeing a golf ball in flight
Never having to use a magnifying glass again

be considered as a possible candidate for the treatment, you
must first be examined by a retina specialist to confirm
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
CentraSight Team Members: Retina Specialist, Low Vision
Low Vision Occupational Therapist
The screening includes several
appointments and a low vision evaluation performed by a low vision
The candidate screening step includes testing your
vision using external telescope simulators. The results of these
help give you and your CentraSight Team a good idea of what
your vision may be like after the telescope implantation surgery
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
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.
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
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
eye drops will be administered to temporarily enlarge your
The surgeon will remove your eye’s natural lens
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.
expect a gradual improvement in your vision of the treated
eye to occur over a period of time, ranging
If you are found to be a candidate, your surgeon
will provide you more detailed information about the procedure
Step 4: Learning To Use Your New Vision
Team Members: Low Vision Optometrist, Low Vision Occupational
After you have recovered from surgery, specially
trained low vision optometrists and occupational
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
