EyeSTAR Technology
The
EyeSTAR Allegretto Wave Eye-Q 400Hz/500Hz Excimer Laser
Safety
The health of your eyes is critical and their safety a fundamental
requirement. Therefore, EyeSTAR LASIK Institute has been using
the Wavelight Allegretto Wave Eye-Q laser, which has a unique
safety feature: PerfectPulse Technology™. This sophisticated
technology ensures that the entire treatment and each pulse
of the laser beam are completely controlled with ultra-fast
eye tracking that follows eye movements 400 times per second,
and adjusts the laser beam accordingly in less than six milliseconds.
So, even when your eye moves, the treatment remains perfectly
centered. It also prevents thermal effects on the eye and dryness,
improving the healing process
Quality of Vision
The Eye-Q laser also offers Wavefront Optimized technology, which
has been shown to preserve the natural shape of the cornea
and prevent the induction of optical errors that could lead
to night vision problems or loss of contrast sensitivity (the
ability to see the images crisply). The system has the potential
to provide a majority of patients with better than 20/20 vision,
which has been coined “eagle vision,” since eagles
have the innate ability to see better than 20/20 both day and
night.
Performance
The Eye-Q system has a frequency of 400 pulses per second and
the actual treatment time lasts only a few seconds as compared
to often longer procedures. An average treatment will take
no more than 10-12 seconds or about the times it takes to pour
a cup of coffee. Shorter eye laser treatments have been shown
to reduce healing time while decreasing the risk of post-operative
infections, over-corrections and under-corrections.

The WaveLight Allegretto Wave Eyetracker
The
EyeSTAR eyetracker is an integral part of EyeSTAR LASIK
treatment. It works
with the laser for an
ultra-precise treatment, ensuring that
each laser pulse is placed exactly where it should be.
EyeSTAR's
eyetracker has a sampling rate faster than 400Hz. and
it follows eye movements 400 times per second. The
reason this is important is because the eye can twitch
at a rate of 60Hz. If your eye twitches faster or at
the same speed as the eyetracker then the eyetracker may
not be able to get the appropriate readings of the movement
of the eye. In turn, the laser may not be able to place
the right pulse of the laser in the appropriate section
of the cornea because of the lack of information.
What is also extremely important is the ability
of the laser to react to the information
being sent to it from the eyetracker. The response time of
the laser must be very fast to ensure that each laser pulse
is placed exactly on the appropriate part of the cornea. Even
if the laser can sample the movement of the eye 1000 times
but the laser reacts slowly to this information, the result
is that the laser may be placing pulses on areas of the cornea
based on old information.The best example of the relationship
between the eyetracker and the laser is to try and imagine
throwing a ball at a moving object that is going 400 miles
an hour. Although you can see the moving object, your reflexes
are too slow to adjust to the constant changes of the moving
object. As a result, every time you throw the ball you are
missing the moving object. The EyeSTAR laser and eyetracker
both work at 400Hz, which means that as the eyetracker is following
the eye 400 times per second, the laser is working at the same
speed, by precisely ablating the necessary areas of the cornea. Return

The
WaveLight Allegro Topolyzer
The
basis for successful eye laser treatment is an accurate
diagnosis. Working with the EyeSTAR ALLEGRO Topolyzer
means utilizing an ideal device to support the decision-making
process
for
customized laser vision correction.
By determining the patient’s
exact visual correction needs, it greatly enhances the
range of possible treatments, from Wavefront
Optimized to the highly sophisticated topography
guided treatment (T-CAT).
The ALLEGRO Topolyzer with its corresponding T-CAT software
has been specifically designed to measure and generate high
resolution treatment data for eyes with
severe irregularities.
It was developed for the most difficult cases, in which standard wavefront
measurement and treatment would prove clinically ineffective.
With an extraordinarily high resolution of the cornea resulting
from 22,000 measuring points and a large placido disc,
the ALLEGRO Topolyzer
is an
accurate tool for the preparation of refractive surgery. In addition
to producing a
refractive map to display the influence of aberrations, the ALLEGRO
Topolyzer is fitted with an interactive elevation map,
allowing the individual
selection of reference body, radius and asphericity.
The WaveLight Allegro
T-CAT Treatment
The ALLEGRO Topolyzer and T-CAT have been optimized
to complete the range of customized laser vision correction and
to interact in perfect synchronization with the ALLEGRETTO WAVE
Eye-Q excimer laser systems. All necessary treatment and patient
parameters are transferred from the ALLEGRO Topolyzer to the
laser. The
ALLEGRO T-CAT software inside the laser´s notebook then
calculates the appropriate correction pattern. The physician
may, however, decide to change individual parameters at any stage
of the process.
The integrated real keratometer and automatic measuring release
allow for precise centration of the image. Digital image
transmission and sub-pixel approximation
combined with a comfortable working distance and a measuring time amounting
to only a fraction of a second allow for the highest possible reproduceability
and accuracy of the data recorded. All data obtained here will be used by
the ALLEGRO T-CAT software to define the respective treatment
parameters.
The ALLEGRO Topolyzer may also be used as
a stand-alone diagnostic instrument for regular topography measurements
which are always required in refractive surgery. Integrated in
the device is a keratoconus detection software and optional pupillometry
software is also available.
Applications for the ALLEGRO Topolyzer include:
- Repair station for decentered/irregular ablations after previous refractive
surgery
- Enlarging small optical zones
- Keratoconus screening
- Treatment of high astigmatism
- Treatment of other surgically induced corneal irregularities

The
WaveLight Allegro Analyzer
The EyeSTAR ALLEGRO Analyzer is an ideal diagnostic device
to support the decision-making process for customized laser vision
correction.
It greatly enhances the range
of possible treatments, from the standard wavefront optimized procedure to
the highly sophisticated wavefront guided treatment.
ALLEGRO A-CAT Treatment
The ALLEGRO Analyzer has been specifically
designed to deliver wavefront data needed to perform safe and
successful wavefront guided laser vision correction. All components
have been
optimized to work in concert with the ALLEGRETTO WAVE Eye-Q laser.
All necessary treatment and patient parameters are transferred
from the ALLEGRO Analyzer to the ALLEGRETTO WAVE Eye-Q laser.
The ALLEGRO A-CAT software inside
the laser notebook computer then calculates the appropriate correction pattern.
ALLEGRO A-CAT (or wavefront guided) treatments are intended
for use on patients
with high incidence of high-order aberrations in their optical system. Any
required correction to the optical path of the eye is then enabled via A-CAT
module on the cornea.
Tscherning Principle
Working in the visible spectrum, the ALLEGRO
Analyzer is designed to make wavefront measurements by utilizing
the Tscherning operating principle, which works as the same principle
as the human eye. In order to perform a measurement according
to this principle, an image of the measurement spots is projected
onto the retina. This allows the physician to constantly verify
that the image has been taken properly and that all measurement
spots are actually valid. The application of this measurement
principle allows for the detection of inaccurate readings caused
by local obstructions.
The application of this principle allows the ALLEGRO Analyzer
to exclusively deliver valid data and minimizes the risk
of false treatment. The ALLEGRO Analyzer
utilizes visible light to perform the measurements, therefore additional
off-line calculations and factoring for chromatic errors
are not required.
Automatic measurement release ensures that only centered
measurements will be taken into account. Minor decentrations
are detected and registered along
with the pupil diameter and other relevant values. These data are then
added to the actual wavefront data. Proprietary WaveLight
data processing software
allows for the registration and recording of valid measurements even
with serious eye conditions.

The
Moria Microkeratome Evolution3 Microkeratome
The Moria Microkeratome Evolution3 Platform is used
in combination with M2 motors powered with CLB. Multiple
heads and motors are used in EyeSTAR to secure a fully sterile
operating environment The Moria microkeratome is unsurpassed
in precision. In fact, this system has been
found twice as precise as the femtosecond
laser microkeratome and it does not cause Transient Light Sensitivity
Syndrome. For microkeratomes, precision means safety, especially
in cases of critical corneal thickness. Besides these pluses
Slow Vacuum Release (SVR) of the system is a critical comfort
component of the Moria.
The NEW INTRALASE
FS-60
EyeSTAR
LASIK Institute is proud to announce its use of the new Intralase
FS-60 flapmaker. IntraLASIK is the latest technological breakthrough
in LASIK. We can now perform an all laser, LASIK procedure.
Laser Vision Correction is often associated solely with the
Excimer laser, but there are actually two very important steps
in correcting your vision:
1. Creating a very thin flap of tissue that is folded back during
treatment.
2. Reshaping the exposed surface with the Excimer laser and
replacing the flap.
