ZYOPTIX: A new frontier in laser eye treatment |
| |
WHAT
IS ZYOPTIX
The very latest
development in laser eye treatement from Bausch
and Lomb is called Zyoptix, a system that takes
LASIK to a new frontier. It is the fully
integrated personalized correction system by Baush
& Lomb that helps patients achieve better
quality of vision. Through wavefront-guided
customised ablation,this latest advancement in
refractive surgery enables the treatment to be
personalised to individual patient.Higher order
aberration,ie irregularities of the eye can be
diagnosed with the aberrometer/machine and the
treatment will then be calculated using an
advanced software.
Personalised
Vision Treatemants
Zyoptix means
that laser eye treatment is now unique to each
eye. With Zyoptix, treatement is designed
specifically to treat your individual vision
erors.
Zyoptix could improve the quality of
of your vision. Available clinical data with us
significantly more Zyoptix patients had less
problems with night driving than patients
undergoing treatement with LASIK.
Each Zyoptix assessment involves an extra diagnostic
(screening) process to let the sergeon understand
your vision better and select the most suitable
treatmentfor you.
In the Zyoptix system the
latest, most advanced technology is used to detect
and treat very small vision erors.
The Zyoptix system has many advanced built-in safety
features that help to optimise the success of your
treatment.
Zyoptix, like standard laser
treatement, is fast and virtually painless.
Why
Lasik
Over the past few years, laser
eye treatment has been seen to make an enormous
difference to people with near-sight, far-sight
and astigmatism. It's a difference that has
changed their quality of life as well as their
quality of vision.
For many people, laser
treatment can mean new freedom -
- freedom to
change the way the world sees you
- freedom
from the time-consuming, day-to-day hassle of
glasses or contact lenses
- freedom to play
sports without the inconvenience of glasses or
contact lenses
- freedom to go on holiday and
to work without worrying about your
eyesight
- freedom to wake up during the
night and see clearly
The result is that more
and more people, including many celebrities, are
choosing to undergo this highly sophisticated and
very successful procedure. Because there is an
increasing number of clinics offering a variety of
methods to correct your vision, it helps if you
have some understanding of all the options, before
you make a decision.
This website is designed
to provide you with information on Zyoptix a new
and advanced laser eye treatment at THIND EYE
HOSPITAL, which we hope will help you to make an
informed choice.
History
Zyoptix has been
developed from LASIK to provide personalised
vision correction and many surgeons believe that
this is the future in laser eye surgery.
What ZYOPTIX can
Correct?
Explaining the differences
between the normal eye and vision errors such as
myopia will help you to understand what laser eye
treatment and Zyoptix are designed to do.
Your
vision can be either normal, myopia (near or short
sighted), hyperopic (for sighted) or astigmatic (complex).Obviously, normal eyes do not need any
correction except at middle age (40 - 50), when
they become presbyopic (old age vision) and
'reading glasses' are needed to see small close up
objects. Laser eye surgery can be applied to
correct near sight, for sight and astigmatism.
The eye is nature's camera. The light that
comes into the eye passes through the curved
surfaces of the cornea and lens, which bends the
light to focus on the retina.
The curvature of
the cornea is very important,. Since it has a
major influence on your type of vision and offers
and ideal surface to correct vision. Laser eye
treatment works by changing the shape of the
cornea to correct or re-align the
focus.
MYPOIA/NEAR (short) - sight :
This is
a very common vision problem and is often
inherited. Myopia people can see very close-up,
but distant images are blurred. This is caused by
the curve of the cornea being too 'steep' or
because eyeball is too long. Laser surgery correct
myopia by flattening the curve of the cornea
pushing the focal point back on to the
retina.
Astigmatism :
Astigmatism is very
common. The cornea is shaped more like a rugby
ball than the normal round cornea and 2 different
curvatures (one rounder than the other) this
simply means that, instead of one curvature (with
standard short or near-sight), there are 2
curvatures that need to be corrected, at the same
time and during the same treatment, to make sure
that there is only one focal point falling on the
retina.
What laser eye treatment does NOT
correct :
Presbyopia : In middle age,
everyone's eyes - whether normal, myopic or
anything else, become presbyopic. This means that
in addition to your distance correction (if you
have one) you will need glasses for close-up
activities.
Neither standard LASIK nor Zyoptix
can correct presbyopia. However, people who have
presbyopia will benefit from having their distance
vision corrected, and will thus only need glasses
for close-up activities.
Choosing the right
Treatment :-
Your eye and vision are like your
fingerprint - truly distinctive and personal. It
is distinctive because light is scattered unevenly
to form a pattern that is unique to your eye and
because your cornea has a unique shape. Each
Zyoptix assessment involves an extra diagnostic
(screening) process extensive enough to let the
surgeon see every individual patient's unique
optical characteristics.
With a Zyoptix
assessment, We at Thind Eye Hospital have an even
broader base of information on which to decide
whether your eyes are suitable for treatment, and
to plan the right treatment for you.
How Zyoptix
works
Zyoptix software combines data
from two different types of d iagnostic equipment,
then programmes the laser with your unique
treatment, based on this data. Data is collected
to assess the structure of your cornea (called
topography). Data is also collected from a
measurement of your optical system using the
advanced wavefront technology - a measurement not
normally taken with Standard Lasik
treatments.
The next sections will explain how
the topographer and wavefront work together to
ensure the most thorough screening and treatment
programme.
The wavefront factor: measuring
your vision :-
Wavefront was first developed by
astrophysicists and has now been applied to
Zyoptix. It provides the most technologically
advanced measurement not just of standard visual
but also of scattered light errors known as
'aberrations'.
Wavefront technology or
aberrometry is based on the principle that if an
eye had no imperfections at all, light passed
through it would not scatter. But because no eye
is perfect, light scatters to form distinct
patterns - called a wavefront. Wavefront
technology measures your personal/individual
patterns and thus allows the surgeon to plan a
treatment that exactly matches individual vision
errors.
Your wavefront will be measured by the
market-leading aberrometer, the Zywave™
Aberrometer from Bausch & Lomb. The Zywave
aberrometer measures the eye from the centre to
the outer edges (the periphery) of the pupil. This
is especially important, because at night your
pupils open up and more light is scattered in the
periphery of the pupils.
Your surgeon needs to
know as much about your night-time as your
day-time vision.
Zyoptix topography:
assessing your corneal surface :-
While it is
important that your surgeon measures your optical
system, it is equally important to know the shape
of your cornea. This screening test enables the
surgeon to assess the general health and thickness
of your cornea and so to determine if you are
suitable for laser eye treatment.
The Zyoptix
system collects this information from over 9,000
points across the cornea, using Bausch &
Lomb's Orbscan™ IIz (anterior segment analysis
system) market-leading topographer.
You may be a good
candidate to Zyoptix if you
- Feel that spectacles/contact lenses are a
nuisance in your job sporting activities or
personal life.
- Suffer from the effect of scattered light
(aberrations)
- Have been told that your pupils are too big,
or your corneas too thin for standard treatment
- Need vision correction and have a
prescription in a high range and -7.00 cylinder
- Have had stable vision for the past 2 years
- Have healthy eyes, good general health and
not taking medication that affects the healing
process
- Are older than 18.
Personal factors
to consider
Career Implications
:
People in certain occupations e.g the Armed
Forces or Technical services probibted form
undergoimg laser treatment Always ask your
employer for advice.
Age: You
surgeon might think it wiose to postpone treatment
if you are under 18
Money: Zyopitix
may be more expensive than standard
LASIK.
PLEASE NOTE : ONLY YOUR SURGEON CAN
DETERMINE IF YOU ARE A SUITABLE CANDIDATE FOR
ZYOPTIX BASED ON APPROPRIANTE DIAGNOSTIC TESTS AND
MEDICAL HISTORY.
Mediocal factors to consider
:-
You will probably be told you are unsuitable
for Zyoptix if you have contraindicated eye or
health problems.
Ocular(eye) health:
Your surgeon will examine you for severe dry eye
conditions, infections,allergies, any corneal
abnormalities or eye disease(either existing or
within your Gp. You will have to postpone your
treatment if you sre pregnant or breast
feedig
General health :-
Your surgeon will
check with you that you do not suffer form
diseases that prevent you form having laser
treatment and may well contact your GP. You will
have to postpone your treatment if you are
pregnant or breast
feeding.
Medication: Certain
medicines might interact with the drops you will
be given.some examples are medication for
migranes(triptans hormone replacement therapy(HRT)
antihistamines and others your surgen will if and
how your medication effects laser treatment be
sure to tell your surgeon about anya current or
past health problems.
What prescription
range can Zyoptix correct?
People
may not realize how suitable they are for laser
treatment, because they wrongly believe that their
eyes are not weak in fact, many patients with mild
to moderate prescription undergo LASIK. But
because Zyoptix removes less tissue than Bausch
and Lomb standard LASIK, it can be performed on
people previously unstable for laser eye
treatments - such as those with hire
prescription.
The limit of what can be
corrected varies from person to person, from
surgeon to surgeon and from machine to
machine.
Alternatives if
you are NOT suitable for Zyoptix
Most people who want Zyoptix are able to have
it, but if not, your surgeon will be happy to
discuss alternatives with you. For example
PRK,LASIK or ICL (implantable contact lens) may be
good alternatives. A few people may have to accept
the fact that they are going to need spectacles or
contact lenses.
Zyoptix : widening the scope
…..
Zyoptix means that people whose eyes were
unsuitable for laser surgery may now be able to
undergo treatment.
…….reflecting your
outlook
Improving your working life is not the
only reason to choose Zyoptix. Many active people
who wear glasses or contact lenses feel they can
never realize their full potential in the sports
and games they enjoy so much…….
Will LASIK
hurt?
After surgery the most common
complaint is a scratchy feeling or the feeling
that something is in the eye when you blink.This
is only due to the flap edges ,which will usually
settle in over the next 24 hours.Most people are
fine with over-the-counter pain medication and
rest..It is unusual to experience severe pain from
refractive surgery.If you do, contact your doctor
immediately.
Is Laser
treatment safe
Like any laser
or surgical procedure ,these treatments are
subject to complication,but the complication rate
is very low.Most complications can be managed.
Excellent
Result
In the world's largest study
evaluation of patient data comparing Zyoptix
treatment with standard LASIK, the results show
that Zyoptix patients had significantly better
vision than patients given standard LASIK.
What results can you
expect?
Significantly more Zyoptix patients had
less problems with night driving than patients
undergoing treatement with a Standard Lasik.
Almost twice as many Zyoptix patients said they
could see better during night driving, in poor or
bright light than standard LASIK patients.
Night

More than 8 out of 10
Zyoptix patients reported same or better quality
of vision in various common light
conditions
Dim

standard LASIK
:-
Do go directly home after your
treatment.You will probably feel best if you rest
for a fewhours.Try to keep your eyes closed as
much as possible.Avoid swimming ,hot tubs and
gardening & keep foreign substances from
entering the eye for one week.Do not rub your
eyes.Just dab gently underneath the eye with the
eye closed.Do not wear eye makeup for 1 week
following your treatment.Post Operative evaluation
will usually be sheduled at 1 day,1 week,1 month,3
months and 1 year after the
surgery. |
