VISX
Star S4 Excimer Laser
VISX Star S4 Smooth Scan
Laser which is one of the most advanced laser
system available in Laser
Vision Correction today. It is FDA-approved
for Wavefront
LASIK and standard PRK
treatment. The S4 offers Active Trak™, an
infrared eye tracking systems that follows the
eye in all three dimensions. The S4 also offers
Variable Spot Scanning™, which uses seven
variable-sized beams for faster, smoother and
more precise treatments. The Blend Zone™
feature enables a larger treatment area and is
available for those with larger pupils, to minimize
night-time glare. VISX Star S4 laser provides
us the best possible treatment options for you.
|
|
The
VISX Star S4 Excimer laser produces a high-energy,
cold, ultraviolet light beam in pulses and delivers
the pulses to a surface of the eye's cornea. These
pulses break the bond between molecules and tissue
cells so that a controlled amount of tissue can
be vaporized away to reshape the cornea. Excimer
laser beams do not disturb the underlying eye
structures such as iris,
lens, and retina. The Excimer
laser is computer controlled and programmed to
treat each individual eye with a high degree of
precision.
Note that
we use the same Visx Star S4 laser for all LASIK
and PRK surgeries including standard PRK,
standard
LASIK, CustomLASIK,
and IntraLase
LASIK. |
|
|
| |
|
|

WaveScan
Analyzer
The Wavefront technology
captures the unique imperfections (irregularities)
in your vision that could not have been measured
before. This gives us the treatment options that
are truly individualized to your visual needs.
(CustomLASIK)
VISX WaveScan
aberrometer (analyzer) is the VISX implementation
of Wavefront technology. The system works by bouncing
a harmless infrared light off your retina. The
reflected beam washes over the internal optical
structures of the eye, emerging as a light wave.
The shape of this wave, or Wavefront, is compared
to that of the optically perfect eye to create
a Wavefront
eye map. This map is used to generate
the surgical plan for Wavefront
LASIK treatment on the VISX S4
Excimer laser.
|
|
WaveScan
produces a very precise, detailed map of light
rays as they travel through your eyes, highlighting
imperfections in your vision. Like fingerprints,
no two Wavefront eye maps are alike. A Wavefront
map of an eye with no visual errors appears to
have a flat surface because all of the light rays
travel evenly through the eye. A Wavefront map
of an eye with visual imperfections appears curved
or distorted because some light rays reach the
retina before others or strike different points
on the retina.
By mapping
both eyes using the WaveScan, a very specific
visual profile, referred to as a Wavefront eye
map (or visual “fingerprint”) is created
for each eye. Your LASIK surgeon programs these
unique profiles into the Excimer laser, customizing
the treatment according to each eye’s distinct
vision corrections needs. It significantly improves
the quality of vision following surgery. |
|
|
| |
|
|
| |
IntraLase
Laser
IntraLase is the first “blade-free”
laser technology for creating the corneal flap
in the initial step of the LASIK
procedure. IntraLase is FDA-approved and it further
minimizes the microkeratome-related complications
of LASIK, be it standard or custom.
IntraLase laser beam places a series of computer-guided,
tiny bubbles within the central layer of the cornea.
This pattern results in a precise corneal flap
at a depth and diameter pre-determined by the
surgeon. IntraLase
technology is a safer, more precise approach in
creating the corneal flap in patients whose corneas
are thin or have unusual curvatures. |
|
|
|
| |
|
|
| |
Microkeratome
For conventional
LASIK, we use a FDA-approved,
one-piece, fully-automated, safe and reliable
microkeratome for creating corneal flaps with
a fixed corneal depth plate. Note that no assembly
or coupling of microkeratome parts by the surgeon
is required during the actual procedure. This
significantly minimizes the potential flap complications
or human error. |
|
|
|

Corneal
Topographer
Corneal Topography System
provides a 3-D image of the cornea in very fine
detail including the condition of the corneal
surface. It is used to diagnose diseases of
the cornea and to monitor changes in the curvature
of the cornea. Auto focus and centering
simplify the collection of data and eliminate
operator bias. A 23 narrow ring, aspheric pattern
with more than 8000 X-Y-Z data points facilitate
greater accuracy; particularly in the peripheral
cornea region. Tangential and Sagittal algorithms
provide enhanced visualization for greater sensitivity
in detecting irregular astigmatisms. |
|
|
|
| |
|
|
| |
Corneal
Topographer
Tomey Corneal Topographer
is designed for high accuracy and patient comfort.
It is a computerized system that measures your
corneal thickness and produces a 3-D map of the
corneal
curvature. It has
applications in a wide range of clinical procedures
such as refractive surgery (LASIK
& PRK).
It can be used both for pre-surgical planning
and post-surgical evaluations. It continues to
set the standard for resolution, accuracy and
corneal coverage. Some of the benefits include
Keratoconus screening and Height maps. |
|
|
|
| |
|
|
| |
Pachymeter
A pachymeter measures the
thickness of the cornea by using ultrasound probe.
Accurate measurement of the thickness of the cornea
is very important in refractive eye surgery, such
as LASIK
and PRK.
For ultrasound pachymetry, a drop of anesthetic
is placed in the eye, and an ultrasound probe
is placed gently onto the surface of the cornea. |
|
|
|
| |
|
|
| |
Auto-Refractors
(Nidek
and Humphrey)
An auto-refractor
measures the near-final prescription
for glasses for the best distance
vision. This near-final prescription is then livered
directly into an auto-phoropter via a computer
cable. The final results require the Doctor’s
subjective interpretation. |
|
|
|
| |
|
|
| |
Several features of an
auto-refractor are:
 |
Spherical
power range is available in plus and minus.
|
|
Cylinder power can be
expressed in plus or minus cylinder. |
|
Axis reading is available
from 1degree to 180 degree. |
 |
Accurate inter-pupillary
distances are given in the readout. This is very
beneficial in fitting monocularly sighted patients,
patients with special needs, and infants, and
can be incorporated into the prescription for
glasses. |
|
Vertex distance is automatically
measured in some of the units and also may be
incorporated into the final prescription. |
|
Pupil size can also be
measured and is useful in fitting rigid lenses
and refractive surgery candidates. |
|
|
| |
|
|
| |
TRS:
Total Refraction System
Total refraction system
analyzes massive amount of visual measurement
data and computes "the most comfortable visual
acuity value" for the patient
automatically. During a near point test, power
convergence and power PD automatically makes adjustments.
The automatic cross cylinder lens makes simultaneous
comparison of cross cylinder charts possible.
Automatic refractor has a full data
|
|
display with high-contrast LCD. Its easy operation
with electronic dial and colored key operation
allows the doctor to keep looking at the patient
while determining the final refraction. |
|
|
| |
|
|
| |
Slit
Lamp
Slit lamp is a table-mounted
binocular microscope that shines a light into
the eye to allow the doctor to examine
the entire eye under high
magnification. |
|
|
|
| |
|
|
| |
Tonometer
With tonometry, the pressure
of the aqueous humor within the eye can be measured.
The aqueous humor is the fluid in the front part
of the eye. Normal pressure within the eye is
8 to 21 millimeters of mercury (mm Hg). Pressure
in the eye is measured to detect
certain types of glaucoma
and monitor its treatment.
Applanation tonometer is
usually attached to a slit lamp. After numbing
the eye with drops, the
|
|
instrument is gently moved until it rests upon
the cornea, while the doctor observes the cornea
through a slit lamp. The amount of pressure it
takes to indent the cornea is related to the pressure
within the eye. |
|
|
| |
|
|
| |
Tonopen
A tonopen is a portable, hand-held
instrument that provides a safe, fast and accurate
method of testing intraocular
pressure. Eye drops that contain a
drug to numb the eye are given, then the instrument
is gently placed on the cornea, and a reading is
obtained. A tonopen is used in emergency to quickly
detect increased
pressure in the eye. |
|
|
|
| |
|
|
| |
Slit
Lamp Imaging
Slit
lamp photos are taken by an ophthalmologist
to document the current condition of the anterior
portion of the eye or eyelid. Taken over a period
of time, such photos allow your doctor to compare
conditions in the eye or on the eyelid. |
|
|
|
| |
|
|
| |
Ophthalmoscopy
An ophthalmoscope is an instrument
that enables a doctor to examine the inside of your
eye. The instrument has an angled mirror, various lenses,
and a light source. With it, a doctor can see the vitreous
humor (the jellylike substance in the eye), the retina,
the optic nerve, and the retinal veins and arteries.
Ophthalmoscopy is painless.
Ophthalmoscopy is useful to detect not only changes
in the retina due to eye disease but also changes due
to certain diseases affecting other parts of the body.
For instance, it is useful to detect the changes that
occur in the retinal blood vessels in people with high
blood pressure, arteriosclerosis, and diabetes mellitus.
Ophthalmoscopy can also be used to diagnose elevated
pressure within the brain, which results in a swelling
(pushing-out) of the normally cupped optic disk (papilledema).
Tumors on the retina can be seen with ophthalmoscopy.
Macular degeneration can be diagnosed with ophthalmoscopy
as well.
|
|
| |
|
|
| |
Direct
Ophthalmoscope
A direct
ophthalmoscope is a handheld
device like a small flashlight with magnifying
lenses that shines a light into the eye to enable
a doctor to examine the cornea, lens, and retina.
The person looks straight ahead as the beam
of light is shown into the eye. |
|
|
|
| |
|
|
| |
Indirect
Ophthalmoscope
Sometimes the doctor uses an instrument called
an indirect
ophthalmoscope, in which a binocular
device is placed on the doctor's head and a handheld
lens is used in front of your eye to focus the
image inside the eye. This method gives a three-dimensional
view, allowing a better view of objects that have
depth, including a detached retina or a swollen
optic disk. It also allows a brighter light source
to be used, which is important if the interior
of the eye is cloudy, for instance due to infection
or cataract. The indirect ophthalmoscope also
allows a much wider field of view than a regular
ophthalmoscope, so that the doctor can examine
more of the retina at once. |
|
|
|
| |
|
|
| |
Retinoscope
Device for measuring an
eye's refractive
error with no response required
from the patient. Light is projected into the
eye, and the movements of the light reflection
from the eye are neutralized (eliminated) with
lenses. |
|
|
|
| |
|
|

Special
Lenses for Fundus Exams
Volk 60D
Lens:
It provides high magnification, making it ideal
for detailed disc and macular viewing. Its 31mm
diameter allows a wide field of view and facilitates
easy handling within the orbital area.
Volk's
SuperField NC: It offers an
ideal 76x magnification and wide field of view
make it perfect as the primary high resolution
slit lamp fundus diagnosis lens. It is designed
for increased working distance from the cornea
(7mm). Its small 30.2mm diameter housing also
proves highly useful for dynamic fundoscopy.
|
|
Goniolens:
It is intended for a stereoscopic examination
of the front camera angle of the eye and laser
coagulation of its structures and also for examining
the central and peripheral areas of the retina.
A Goniolens is handy in operation and fixes well
in the eye slit. It is used together with slit
lamps of any type and with ophthalmocoagulators.
The lens ensures the following:
- A specially comfortable,
high quality observation of the iridous-corneal
angle;
- A possibility of carrying
out, due to its design, in the majority of cases,
an accurate anatomic diagnostics of the structure
peculiarities of the front camera angle without
any additional manipulations;
- Carrying out the Forbes' test
with a removed haptic attachment;
- A stereoscopic observation
of the near-equatorial area and far peripheral
of the retina with a sufficient (no less than
5mm) mydriasis of the pupil.
Fundus
Contact Lens: It is a diagnostic
aid that makes a difficult diagnosis simple. The
combination of binocular vision, great light intensity
and a range of magnification powers using the
fundus contact lens and the slit lamp give your
ophthalmologist an excellent resolution to view
the fundus. |
|
|
| |
|
|
| |
Digital
Fundus Camera
This camera system allows
us to capture highly accurate color-digital
images of your retina. Captured images can be
stored for comparison, e-mailed, and / or directly
printed as hard copy. The most common causes
of blindness are glaucoma
and diabetic
retinopathy. For the best ophthalmologic
care, it is important to trace these disorders
in their early stages. When used with injected
flourescein contrast dye, these images point
out leaking blood vessels for laser therapy
from diseases like diabetes. |
|
|
|
| |
|
|
| |
A-Scan
It is a type of ultrasound,
radar-like device that emits very high frequency
waves that are reflected by the ocular structures
and converted into electrical impulses. It is
used for differentiating normal and abnormal
eye tissue or for measuring length of eyeball.
It also helps in determining the refractive
power of the intraocular lens implant that is
used to replace your eye's own cloudy lens in
cataract
surgery. |
|
|
|
| |
|
|
| |
|
|
| |
|
|
| |
Phacoemulsifier
It is a sophisticated machine
that sends ultrasonic vibrations to a tiny probe
that has been inserted through an incision into
the cloudy lens that constitutes the cataract.
Vibrating at about 40,000 cycles per second, this
probe emulsifies or breaks up the cataract
into pieces so small that they can be vacuumed
from the lens capsule of the eye. The phaco machine
also provides the vacuum necessary to remove these
particles through the hollow center of the probe.
At the same time, it introduces an irrigation
solution that maintains pressure and prevents
the eye from collapsing. |
|
|
|
| |
|
|

BAT
(Brightness Acuity Tester)
BAT is used to test glare
disability. The Brightness Acuity Tester can simulate
three bright light conditions: 1) Direct overhead
sunlight; 2) Partly cloudy day; 3) Bright overhead
commercial lighting. The vision is measured using
the low, medium or high light settings of the
BAT. If the vision falls with light then the patient
is deemed to have glare disability.
Conditions
of glare and low lighting arise in the course
of many workplace tasks (e.g., driving, |
|
construction
work, computer use). Strong extraneous light sources
such as oncoming headlights or a bright sky often
surround a visual target, creating glare problems.
In addition to the cataract
causing glare, light scatter from airborne particles
or irregularities on otherwise transparent surfaces,
such as windows and spectacle lenses may also
contribute to glare. The impact of glare depends
on the demands of the visual task. For example,
when looking at a person silhouetted against a
window or a very bright sky, contrast reduction
can make it difficult to discern features in the
face. In driving, detecting pedestrians, the edge
of the roadways or reading signs against a bright
sky, sun, or headlights is likely to be difficult
if ability to see in the presence of glare is
impaired. |
|
|
| |
|
|
| |
PAM
(Potential Acuity Meter)
A potential acuity measurement
is sometimes appropriate as an estimate of potential
vision prior to a surgical procedure, especially
cataract
surgery. The potential acuity meter (PAM) is a
device that is designed to project an eye chart
directly onto the retina. This allows the examiner
to test the visual
acuity without interference from
the cloudy lens. The main purpose of performing
this test is to get an idea of the visual acuity
that the patient can potentially achieve. Prior
to committing to cataract surgery it helps to
know that vision improvement is possible (meaning
there are no retinal
or neurological problems that will not allow vision
improvement despite cataract removal).
|
|
|
|
| |
|
|
| |
YAG
Laser
Some patients develop haze
of a membrane behind the intraocular lens (IOL)
implant following
cataract surgery which results in
diminished vision. The vision may be blurred,
hazy, or is associated with significant glare
and loss of visual
acuity. In past years, such membranes
needed to be cut with a very tiny knife. In recent
years, opening is made with a special type of
laser, commonly nicknamed as "YAG
laser".
|
|
The
YAG laser creates a series of tiny explosions
which literally shear apart the membranes. Thus,
if you have already had cataract surgery and should
you experience decreased vision because of this
secondary membrane, the YAG laser may promptly
restore your vision with a simple outpatient procedure. |
|
|
| |
|
|
| |
Visual
Field Analyzer (Humphrey)
The visual field is the
entire area of vision that one sees out of each
eye, including the corners (peripheral vision).
The visual field is tested if a person notices
specific changes in vision, for example, if he
keeps bumping into objects on one side. Visual
field testing helps your ophthalmologist
in the diagnosis and management of loss of vision,
glaucoma,
disorders
of retina, brain tumors, and
strokes. |
|
For
performing this test, one of your eyes is temporarily
patched. You will sit in front of a large, concave
dome-shaped instrument and you will be asked to
look at a central target within the dome. A computer-driven
program flashes small lights of varying intensities
at different locations within the dome’s
surface, and you press a button when you see lights
in your peripheral vision. Your responses are
compared to age-matched controls to determine
the presence of defects within your visual field.
No special preparation is necessary for the test.
This test finally produces a map of your complete
field of vision. Your ophthalmologist will interpret
the results and discuss with you. |
|
|
| |
|
|
| |
Visual
Field Analyzer (Goldmann)
Today, automated (computerized)
field analyzers, such as the Humphrey or the
Octopus perimeters are used to perform the field
of vision test. However, there is a different
type of perimeter, Goldmann perimeter, which
is used in special circumstances such as in
patients with limited cooperation or poor vision.
Depending upon the size of the test stimulus,
a Goldmann perimeter maps out the outer margins
of the visual field. Current visual field criteria
that define legal
blindness in the US are based on
Goldmann perimeter. |

HRT:
Heidelberg Retinal Tomograph
The Heidelberg Retina Tomograph
(HRT) is a non-invasive confocal scanning laser
microscope that is used to obtain a three-dimensional,
computerized scan (like a CAT scan) of your optic
nerve head and retina in the posterior segment.
Due to its ability to produce highly accurate
and reproducible topographic images, this sophisticated
technology is applied effectively to diagnosing
early glaucoma
and monitoring the progression of glaucoma, as
well as, evaluating macular holes or edema. Today,
HRT is the gold standard for imaging the optic
nerve.
|
|
HRT
does not replace a visual
field test. A visual field evaluates
your level of visual function. However, the structural
damage from glaucoma occurs up to five years prior
to the patient experiencing vision loss. With
HRT a personalized visual map of your retina and
optic nerve is compared (by computer technology)
to the new scan, and any changes are highlighted.
Your doctor can immediately see if your glaucoma
is progressing and then prescribe needed therapies,
before vision loss is experienced. |

Radio-Surgery
Unit
It uses advanced radio-wave
technology that provides unparalleled surgical
control, precision, versatility, and safety. A
fine tungsten-wire surgical electrode, emitting
radio-waves at 3.8MHz, glides through tissue with
no pressure. The cutting effect, known as electro-section,
is performed without crushing cells. Heat is generated
by resistance to the passage of a radio frequency
wave which disintegrates and volatizes the cells
in its path. It causes the tissue to split apart
as if it had been cut with a sharp razor-blade.
An equally significant advantage is that the electrode
is self-sterilizing while in use, diminishing
the likelihood of post procedure infection.
|
|
| Clinical benefits
include reduced post-operative discomfort, minimal
scar formation, enhanced healing and excellent cosmetic
results. Radio-surgery
is an in-office procedure, which is used to safely
and effectively remove eyelid margin lesions, skin
tags, warts, and moles. |
|
|
| |
|
|
| |
Surgical
Microscope
A Surgical
Microscope has a wide application
in ophthalmology. Focusing control, zooming
and coordinate displacement of the microscope
optical head are the critical components of
a surgical microscope. Reflex-free optics of
the microscope forms a contrast image of high
resolution and chromatic rendering. Surgeon
and the assistant(s) can work with mounted photo
adapter or video camera with improved chromatic
rendering. |
|
|
|
| |
|
|
| |
Sterilizers
The Statim sterilizes
instruments in less than five minutes. A forced
steam injector begins sterilization in less
than three minutes. Fast heat up and cool down
greatly reduces the total time instruments spend
in moist heat conditions. Instruments that once
were bathed in antiseptic solution can now be
sterilized. The Statim uses pure steam only
once. Condensate is discarded after each cycle.
Conventional autoclaves re- |
|
circulate
harmful contaminants through a closed water
system. Entire sterilization cycle, including
instrument drying, is computer controlled for
foolproof operation. |
|
|
| |
|
|
| |
|
|
| |
|
|
| |
Pupillary
Distance Meter
It is a hand-held portable
instrument that measures the precise inter-pupillary
distance.
Inter-pupillary distance (PD) is the distance,
in millimeters, from one pupil center to the
other. PD measurement is used to ensure proper
lens placement in a frame. |
|
|
|
| |
|
|
| |
Sun
Meter
Measurements of UV
passing through the lens are
in-credibly crucial to protect patients’
eyes and maintain a high standard of quality and
eye health. A Sun Meter allows us to quickly and
accurately measure the transmittance or absorption
percentage of ultra-violet light in any lens material.
Having automatic calibration and three LED displays
which signify safe, caution, and danger levels,
it reads UVA light transmission up to 400nm. |
|
|

Hot
Air Frame Warmer
TempMaster deluxe is a hot
air frame warmer with multiple speeds and temperature
settings. It speeds and simplifies frame
adjustment and repair. Its 2
heat settings, separate cooling setting, and multiple
fan speeds provides the precise control for even
the most delicate frames. |

Voiceless
Communication System
NeoVision
is equipped with a special communication device
which allows inter-office communication to be
fast, quiet, and discrete. It transmits important
messages in all work areas through lighted buttons.
Simple, readable meanings are assigned to colored
and engraved lights, identifying People, Actions,
and Places. The intended (assigned) staff member
responds by adding to or by resetting (acknowledging)
the light buttons. Lights are illuminated only
when a message is sent, and they remain extinguished
for up to 90% of the working day. This communication
system offers the following benefits: |
|
|
|
| |
-
Requests
staff silently;
-
Directs
staff without knowing where they are;
-
Informs
staff of changing patient status;
-
Informs
staff of phone calls and reply silently;
-
Knows
where each doctor is;
-
Knows which
rooms have patients;
-
Knows which
patient to see next;
-
Knows how
many patients await each doctor.
