Mikrokeratome Amadeus II ( AMO )
The modern technology of this instrument manufactured by AMO of Ireland, separates the layer of corneal flap very thin and with very high accuracy. This echnique is proven to accelerate the healing process.
The superior quality of this instrument is reflected in an article, in the magazine “EyeWorld Asia Pacific”, edition June 2006. In a study by Dr. Chu from Santa Ana, California, he writes:
“Based on the results of the study, more than 90% of the patients 3 months
after LASIK using Amadeus II reached a visual acuity of 20/20 (normal), whereas
only 80% of the patients 3 months after LASIK using the Intralase Femtosecond
Laser (flap made with a laser, not a knife) reached a visual acuity of 20/20.
The LASIK procedure using Intralase requires a waiting time of 10-20 minutes. The
LASIK procedure using Amadeus II does not need a waiting time of 10-20 minutes
and this procedure can be done immediately without waiting.

Mel 80
I Care Lasik uses the Mel-80 Carl Zeiss instrument which features Advanced Aspheric Lasik Technology. This technology, the first to be used in Indonesia, keeps the natural shape of the cornea so that the vision is as sharp as the natural condition.
THE BENEFITS IN USING THE ADVANCED ASPHERIC LASIK COMPARED
TO LASIK ARE:
Less glare at night
Only a thin layer of the cornea is needed for the procedure
Diminishes corneal aberrations so that vision is clear and comfortable
Keeps the natural shape of the cornea so that the quality of vision is more perfect
Other special features of the Mel-80 are:
The instrument is made in Germany by Carl Zeiss. Carl Zeiss has for many years had a superior reputation for its first class optical products and technology. Even the Sony camera and the Nokia cellular phone use optics from Carl Zeiss. Japan, well known for its high standard of quality, will often choose to use products originating from Carl Zeiss.
The lasik machine has a very high emission speed of 250 hertz.
The instrument has an automatic eye- tracker with an emission of also 250 hertz, which is perfectly synchronized with the laser machine.
The instrument possesses a Gaussian beam of 0.70mm. This is the smallest type of laser beam so that the surface of the eye lasered will be finer and the healing process will be faster. The Gaussian beam on other lasik instruments possesses a beam of about 1-4 mm, with the result that the eye lasered will be more rough. The
Mel-80 is so fast and precise that it shortens ablation time remarkably and the shortened exposure time allows for faster recovery. The Gaussian beam profile allows finest corrections even of high order aberrations without losing the benefit of smooth ablations.
The instrument has iris recognition, which can prevent the risk of making an error in recognizing the cornea. It also prevents against cyclo-torsion because of the difference in the data and therapy when sitting and lying down.
OUR TECHNOLOGY
Carl Zeiss continues to lead the way in precision optical technology for medical devices and other instruments. Dedicated to constantly improving the customized ablation procedure, it developed the CRS-Master, which integrates data from the WASCA wavefront aberrometer and the Atlas Corneal Topographer and transfers it to the MEL-80 excimer platform. This allows topography guided corrections (for previous excimer laser treatments), wavefront or customized laser treatments, and detection of minute disturbances in the cornea for optimal treatment outcomes.

Wasca Analyzer
The WASCA Analyzer is an aberometer which is an instrument used to measure aberrations. Wavefront analysis with the WASCA Analyzer provides the patient with new, exciting possibilities for ophthalmic diagnosis. Unlike existing diagnostic techniques, the WASCA Analyzer analyzes the optical properties of the entire eye—from the corneal to the retina. In addition to the refractive values, the WASCA Analyzer also supplies higher order aberrations, which were largely ignored in the past. The WASCA Analyzer provides the specialists with an objective result for an exact diagnosis. It will help them select the most suitable form of therapy for your eye, for example, wave-front guided excimer therapy for significant higher order aberrations.
The WASCA Analyzer is very advanced technology with high resolution. The heart of
the instrument is a high resolution sensor for the analysis of the wavefront aberrations. With a total of 1452 measuring points or approximately 800 measuring points in a 7 mm pupil, the sensor guarantees unparalleled detail resolution and measuring accuracy. Together with an innovative optical system, this, rules out the possibility of such effects such as overlapping, hence even allowing the measurement of eyes with very severe aberrations. The extremely short measuring time of 13 milliseconds prevents eye movements from influencing the accuracy of the result.
Not all wavefront analyzers are the same. The WASCA Analyzer uses the Shack-Hartman wavefront method, which is the gold standard for true wavefront analysis.

Atlas Topography
Instruments designed specifically for measurement of the corneal topography had its beginnings in 1880 with Placido’s disk, which forms an image of a concentric-ring target on the cornea. This instrument does not allow for quantification of corneal toricity or peripheral flattening.
The Humphrey-Zeiss Atlas Corneal Topographer utilizes the placido disk technology
to acquire images of the corneal surface. Current software technology captures the eflected images with a digital camera, processes the data, and displays the information in multiple formats.
The Atlas Corneal Topographer software provides information that is similar to most other placido disk topographers. Several types of maps can be created using the software. They include axial maps, which describe the radius of curvature of the cornea relative to the optic axis, curvature maps, which portray the radius of the curvature independent of the optic axis, and elevation maps, which illustrate the radius relative to a reference sphere.
Each of these maps has a unique purpose. For example, axial maps describe power, curvature maps depict shape, and elevation maps demonstrate areas that are above or below the average ideal surface. The Atlas Corneal Topographer lets the doctor develop a template that can portray any or all of the above-mentioned maps. Additionally, it allows for corneal shape analysis through an artificial intelligence program that can identify variations of normal as well as kerataconus suspects and patients with distorted corneas.
At the heart of the system is Humphrey-Zeiss System’s unique, patented MasterVue software. The MasterVue System’s Cone of Focus technology and Arc-Step Algorithm permit accurate and high- resolution corneal measurement.
Humphrey-Zeiss Atlas Topographer has a wide variety of maps that define the refractive corneal surface power that can be displayed on one print out. The axial maps demonstrate corneal curvature and degree of astigmatism. Elevation maps indicate the degree of elevation above or below the green reference color. Hot colors such as red and orange represent areas above the green reference color while various shades of blue indicate areas belowit.

CRS
MASTER II
This instrument gives personal correction by integrating the wavefront diagnosis obtained with the WASCA Analyzer into therapy with the MEL-80. However, it can do much more besides. If treatment planning is to be truly customized, it must take into account not only wavefront data, but all the relevant parameters of each individual patient.
On the basis of the highly accurate wavefront data from the WASCA Analyzer, the CRS-Master II allows the diagnosis and treatment planning required for the correction of the patients complete refractive errror, including the higher order aberrations previously ignored.
Customized aberration correction demands the utmost precision from the excimer laser. To guarantee the degree of accuracy required, the CRS-Master II adapts the laser energy to each patient’s corneal curvature. Together with the aberration Smart Lens Design of the MEL-80, the extremely accurate ablation creates an optimum basis for the correction of even the smallest irregular refractive errors.
In the development of the CRS-Master II, prime importance was attached not only to the optimization of therapy, but also to safety. During all phases of treatment planning, the residual stromal thickness is monitored.
In the treatment planning process, all relevant parameters are displayed on a clearly structured interface. To permit fast, convenient treatment planning in everyday
clinical use, the CRS-Master II offers practical, meaningful presets.
The CRS-Master II is truly customized therapy meeting the needs of each individual
patient giving personalized correction, personalized precision, and personalized safety.

CV3000 ( Topcon )
This instrument is a CompuVision phoroptor, which combines a new design with modern technologies. It ensures the operator improved efficiency and optimum performance utilizing the very latest in refractive techniques. The automated vision tester provides more accurate Rx’s as well as enhanced ergonomics. The instrument is practical, efficient, convenient, fast, and comfortable for the operator and patient.
The CV-3000 Compu-Vision is unique in offering a variety of controls and combinations with an array of Topcon chart projectors and mirror chart systems. The instrument switch layout and software design ensures fast and smooth operation and lens rotation. A disadvantage of the traditional dial-spinning refractor is the amount of time and skill needed to arrive at an accurate Rx. There are no manual adjustment knobs on the CV-3000 control head unit, and all instrument inputs are made on a touch screen.
Pre-test data can be transferred directly to the refractor, eliminating copy errors that can occur when writing down lensometry or autorefractive readings. The operator may
choose to start with either the lensometry or the autorefraction data automatically
set in the CV-3000. The unit’s high speed lens selection is a real time saver once the data has been entered. The entire refractive sequence can be programmed into the unit and multiple programs can be saved or personalized.
As electronic medical records (EMR’s) become the gold standard in patient care, it is vital to have equipment that easily connects to this system. The CV-3000 can transfer
data to most EMR programs to reduce copying error and tedious paper shuffling.
