Product Description

Atlas 9000 Placido Disk Technology

Patented Placido Disk Technology

Placido-disk-drawing-2

Triangulation with Cone-of-Focus, Placido rings, and corneal surface

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 your 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
  • Less dependence on operator technique means greater efficiency and fewer repeat exams

Corneal Wavefront Analysis

A valuable tool for patient education and treatment selection

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
  • View changes in contrast sensitivity through the modulation transfer function (MTF)

Automatic Horizontal Visible Iris Diameter (HVID)

Automatic Horizontal Visible Iris Diameter (HVID) or “white to white” measurement simplifies the selection of contact lenses

Easily measure and display HVID

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

PathFinder II Corneal Analysis Software

Take the art out of topography analysis

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, PathFinder II provides probabilities for 5 different corneal conditions by comparing topography exams to an extensive clinical database.

PathFinder II summary screen

1. Comprehensive Clinical Database

PathFinder II 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

pathfinder II next generation analysis software

Mean curvature analysis eliminates corneal astigmatism to reveal underlying corneal irregularities

2. Sophisticated, Next-Generation Analysis Software

Overcoming limitations inherent in traditional corneal topography, PathFinder II 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 PathFinder II’s extensive clinical database.

3. Results You Can Use

You can count on PathFinder II to make topography analysis simple and reliable.

  • Validation of PathFinder II with an independent data set demonstrated greater than 90% sensitivity, specificity, and accuracy in detecting normal versus abnormal corneas**.
  • Color-coding of PathFinder II parameters quickly indicates which parameters are beyond normal limits any may contribute to specific classifications.
  • PathFinder II results may also be tracked over time to monitor changes in probabilities.

masterfit contact lens software

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. MasterFit II 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
