Atlas 9000 Topography Diagnostic Equipment
Central Arkansas Veterans Health Care System
Atlas 9000 Topography Diagnostic Equipment for Little Rock VA Eye Clinic
13-Jul-18
Scope
The Zeiss Atlas 9000 will be received at CAVHS warehouse, Bldg 182, at 2200 Fort Roots Drive, North Little Rock, Arkansas. After inspection and internal identification by Biomed Department it will be placed in the Little Rock VA Eye Clinic at 4301 W. 7th Street, Little Rock, AR 72205.
Zeiss Atlas 9000 will provide standardization of eye care for cataract surgery cases, and corneal topography for patients. This machine is used to measure the eye in determining the Corneal Topography of the patients Cornea because this device will aid the physicians in a treatment plan for the Veteran. Also, if we are unable to do these measurements, the facility will be unable to perform these surgeries.

The Atlas 9000 is a stand-alone system.
Usage of the Several Devices & Registration Link
The Atlas System delivers the clinical accuracy essential to today s eye care practice, now in a more powerful and easier to use platform. With applications including contact lens fitting, pathology detection and management, and selection of aspheric IOLs, the new ATLAS 9000 System is the right choice for reliable real-world results, every time, from virtually any operator.
Specifications
2.5.1 Corneal Topography
Suggested Manufacturer Brand Name: Carl Zeiss Atlas 9000 OR EQUIVALENT as listed below:
Placido Disk Technology with Cone-of-Focus Alignment System
Proven, patented technology
Patented Cone-of-Focus Alignment System and Arc-Step Algorithm deliver sub-micron elevation accuracy
Using triangulation, the advanced ATLAS Arc-Step algorithm provides reliable surface reconstruction
22-ring Placido disk optimized to avoid ring crossover, which means reliable results for a wide range of patients
Long, comfortable 70 mm working distance minimizes focusing error found in small cone systems
SmartCapture Image Analysis
Technology that helps the staff get the right image the first time
SmartCapture analyzes 15 digital images per second during alignment and automatically selects the highest quality image
Next-generation image processing provides more repeatable, reliable results, even in difficult cases

Corneal Wavefront Analysis takes corneal topography to a new dimension. Using ray tracing technology, the Atlas displays higher-order corneal aberrations, providing valuable insight for patient education and treatment planning.
Educate patients about higher-order aberrations and simulate visual acuity
Assess corneal refraction with image simulation and point spread function
Measure corneal spherical aberration with Zernike analysis to optimize the selection of aspheric IOLs
View the effects of individual higher order corneal aberrations

Scotopic and photopic pupil images
Automatic Horizontal Visible Iris Diameter (HVID) or white to white measurement simplifies the selection of contact lenses
Easily measure and display HVID for both eyes with OD/OS Comparison Display
Automatic Pupillometry and HVID Measurement
Tools that enhance contact lens fitting and refractive surgery planning
Pupil size, measured at two levels of illumination (scotopic and photopic @700 nm), provides insight into optical zone under varying light conditions.
View centration of LASIK or orthokeratology treatment in relation to pupil center to assess treatment effectiveness
Improve multifocal contact lenses selection by understanding patient's pupil size at two levels of illumination
Streamline contact lens selection and fitting with automatic Horizontal Visible Iris Diameter (HVID) measurement
Ergonomic Design
Ideally suited for operator and patients
Compact, integrated system with powerful computer and analysis software
Unique chinrest positions patient for easy image capture and wide peripheral coverage and automatically detects OD/OS
Non-visible Placido ring illumination is comfortable for even the most light-sensitive patients
PathFinder II Corneal Analysis Software
PathFinder II Corneal Analysis Software for the ATLAS Corneal Topography System (Model 9000) is a comprehensive, easy to understand, and reliable anterior topographic screening tool to assist with refractive surgery screening and to help identify abnormal corneal conditions for monitoring and follow-up. Using next-generation analysis technology, This software provides probabilities for 5 different corneal conditions by comparing topography exams to an extensive clinical database.
PathFinder II summary screen
1. Comprehensive Clinical Database
Software that features a statistically significant clinical database established from a multicenter clinical study that characterized 5 different corneal conditions including:
Normal corneas
Suspect/clinical keratoconus
Myopic laser vision correction
Hyperopic laser vision correction
Other non-normal conditions such as corneal transplant
Mean curvature analysis eliminates corneal astigmatism to reveal underlying corneal irregularities
2. Software
This software incorporates novel three-dimensional mean curvature analysis, which has been shown to be very sensitive to detecting corneal shape abnormalities such as keratoconus*. An advanced Support Vector Machine algorthim analyzes multiple parameters from the mean curvature map and compares them to other maps in the extensive clinical database.
3. Analysis:
The software to makes topography analysis simple and reliable.
Validation of software with an independent data set demonstrated greater than 90% sensitivity, specificity, and accuracy in detecting normal versus abnormal corneas**.
Color-coding of software parameters quickly indicates which parameters are beyond normal limits any may contribute to specific classifications.
The results may also be tracked over time to monitor changes in probabilities.
MasterFit Contact Lens Software
MasterFit Contact Lens Software helps streamline the fitting of gas permeable (GP) lenses.
Corneal conditions such as asymmetrical astigmatism, a decentered apex, contact lens warpage, and irregular, peripheral and central astigmatism can dramatically affect the way a contact lens behaves on the eye. This software allows customized fitting of GP lenses according to your own fitting preferences.
Simulate fluorescein patterns for custom and stock lenses, including spherical, toric, and aspheric designs
Automatically design lenses to your preferences by customizing fitting options such as desired tear film clearance
Improve trial lens fitting efficiency by adjusting lens parameters, such as peripheral curves, and simulating lens movement to compensate for lens-to-cornea relationship
Email lens design and topography exam to your lab for efficient ordering and fulfillment

Maintenance
Atlas 9000 is a precision optical instrument. Please protect the instrument from dust and moisture and avoid subjecting it to shocks or strong forces.
The non-optical surfaces of the instrument can be cleaned and/or disinfected whenever necessary. Any standard cleaning product appropriate for plastic surfaces that does not contain acetone or hydrogen peroxide (e.g. ethanol and isopropyl alcohol disinfectants) may be used for this purpose. Before doing this, please turn the instrument off and pull out the power plug.
The lens surface at the front of the laser scanning camera should be carefully cleaned at regular intervals. For this purpose, it is best to use a cotton swab slightly moistened with pure (99.9%) ethyl alcohol.
Please be aware that only authorized service personnel can do service and repair operations of the Atlas 9000. Do not open the device. If the device is opened by someone other than an authorized service personnel, the warranty will be discontinued. If the device fails please call your local distributor or the Zeiss Engineering support department.
A yearly inspection of the device by a Zeiss Engineering service engineer is highly recommended to ensure proper and exact operation.
Training
Zeiss rep will conduct training at time of installation.
Delivery & Installation
All items will be delivered per VA Policy.
To ensure the overall safety of the system, only certified staff of your local Zeiss Engineering distributor must install the Atlas 9000.
All power plugs of the Atlas 9000 system (computer, monitor, printer, IOLMaster 700 power supply, table) must be connected to the isolation transformer.
WARNING: The system must not be operated without IEC 60601-1 approved isolation transformer. (please refer to chapter 1.3.3 Cautions and Warnings )
All cable connections between camera, laser box and computer must be carried out according to the following connection scheme. All cables must be in good condition and properly connected.
