Assess full corneal and lenticular optical quality at a glance with the new Full Sequence Overview display and enjoy clarity for you and your cataract patients. The Pentacam® AXL Wave is the only device that allows you to truly separate the lenticular aberrations and total corneal aberrations with complete data from the back surface, from the complete visual system.

Aberrometry, biometry, and tomography measurement results are displayed numerically and visually on one screen, with abnormal values highlighted automatically. Easily compare daytime and nighttime pupil diameter side-by-side. Streamline your workflow using one device to efficiently select the best premium IOL for your patients with the new Full Sequence Overview Display.

Premium IOL conversations with patients are more effective with educational visual aids that convey the benefits and establish realistic expectations to boost satisfaction with outcomes. Using Wavefront data, the Full Sequence Overview Display creates visual simulations to help patients understand how their IOL selection and any existing corneal abnormalities will impact their vision post-lens surgery.

This display also assists you in performing efficient, comprehensive screening for corneal diseases and abnormalities in order to select the right procedure that best fits each patient, improving outcomes and boosting satisfaction with results.

General Overview


  • Comprehensive overview
  • Patient consultation


The General Overview provides important information on the keratometry and pachymetry of the cornea in concise numerical form. The Scheimpflug image provides ophthalmologists and their patients with intuitive representations of opacities of the cornea or lens (cataract) or of the position of existing IOLs. The anterior chamber is described in terms of anterior chamber depth, volume and angle. When combined with IOP tonometry readings corrected for corneal thickness the General Overview permits an assessment of glaucoma risk. It also allows the display of all color maps.

Fast Screening Report


  • Quick detection of irregularities
  • Patient consultation


The Fast Screening Report provides an intuitive guide to review the Pentacam® results. It is a great tool for detecting abnormalities and to quickly screen new patients. Normative data is gathered from published studies and stored in the Pentacam® software. The distribution of normal values in a population is represented by the bars shaded in gray. The diagrams show the distribution for normal (green) and pathological (red) eyes. Sources, which the evaluations are based on, are cited to provide additional information. In cases of irregularities, the individual displays for detailed findings appear in the interactive navigation bar.

Pachymetry maps, absolute and relative


  • Pre-surgical planning of refractive corneal surgery
  • Anterior chamber angle screening
  • Detection and quantification of abnormalities in corneal shape
  • IOP evaluation taking into account measured corneal thickness based on various formulas (for ex. the Dresden correction table)


An overview display in colour shows the corneal thickness from limbus to limbus. The measured values can be displayed in a pre-determined grid or represented manually at any point at a mouse click.

Automatic representation of:

  • corneal thickness in the centre of the pupil
  • corneal thickness in the apex
  • the thinnest point of the cornea
  • corneal volume

Scheimpflug Image Overview


  • Check images for disruption due to blinking
  • All Scheimpflug images at a glance


All Scheimpflug images are shown. This makes it possible, for example, to spot interferences with the measurement process (light, blinking by the patient etc.) at a glance. This display appears directly after completion of the measurement, providing the option of stopping further calculations and repeating the measurement. However, this is not intended as an alternative to the automatic assessment of image quality, displayed as QS (quality specification).

The display is also useful for detecting first signs of opacification of the cornea or crystalline lens.  



  • Changes which become visible in the Scheimpflug image are lucidly represented in a 3D model.
  • Anterior segment tomography


The rotatable, pivotable 3D model of the eye proves to be an enormous help when consulting with patients, as it permits the patient to see his or her eye from all sides so that irregularities can easily be explained. It provides a view of the anterior segment as a whole as well as separate views of the cornea and crystalline lens.



  • Display of eccentricity results by zone
  • Topography of the anterior and posterior corneal surface


The rotating measurement principle guarantees high resolution output for the central cornea. The topographic analysis of the anterior and posterior corneal surfaces is based on the measured elevation data.

  • Display of sagittal and tangential curvature of radius and refractive power
  • Various elevation maps based on freely selectable reference surfaces
  • Determination of true net corneal power with due consideration also to the posterior corneal surface
  • Various four-map displays with default or freely configurable settings
  • Subtractive and comparative representations of various examinations

Belin ABCD KC-Staging

The new Belin ABCD KC-Staging Display shows, at a glance, all parameters relevant to kc classification, including the posterior corneal surface. The display can also be put to retrospective use, i.e., for classification of a patient’s earlier examination data.

Belin ABCD Progression Display


  • KC progression for up to eight exams per eye
  • Direct comparison of right and left eye
  • Retrospective application


The Belin ABCD Progression Display allows direct comparison of up to eight exams per eye. The four parameters A (= anterior radius of curvature in 3 mm Zone), B (= back/posterior radius of curvature in 3 mm Zone), C (= corneal thickness at thinnest point) and D (= distance corrected visual acuity - DCVA) are displayed side by side to easily visually determine a trend of progression or depression (according to CXL). Each individual exam can be marked as baseline/reference (first exam by default) or as first exam after a cross-linking treatment (white/black bar line). The red and green lines describe the respective confidence intervals (CI). The red lines describe the group with kc, the green lines the normal/healthy group. The solid lines indicate the 95 % CI and the dashed lines the 80 % CI. The Belin ABCD KC Staging (Topometric/KC-Staging) and the Belin ABCD Progression Display can be used retrospectively.

Compare 2 Exams

The Holladay Report was developed in collaboration with Jack T. Holladay, M.D. It supplies data for calculating the optimal IOL refractive power for patients who have undergone refractive corneal surgery such as LASIK, PRK and RK. It determines total corneal power, displaying it in terms of EKRs for different zones.

PNS and 3D Cataract Analysis


  • Cataract classification
  • Determination of lens opacities in 3D


Opacities of the cornea, crystalline lens or of IOLs, e.g. PCO (posterior capsular opacification) are made visible by blue light illumination. The software allows automatic and objective three-dimensional quantification of lens opacity. This offers the advantage of an optimal follow-up of cataract patients. The Pentacam® Nucleus Staging Module, „PNS“ for short, was developed in collaboration with Dr. Donald Nixon. This parameter is helpful in optimizing the settings of phaco machines. It is also useful in femto laser assisted cataract surgery.

Corneal Optical Densitometry


  • Location of corneal opacities
  • Assessment of the depth and degree of opacification


This software provides a standardized method of selective quantification of corneal opacities. The maximum and average corneal opacity is displayed in a color map. Opacities can also be viewed in selected layers. Corneal opacities are shown for defined annuli and depths, facilitating uniform evaluation. This function served as a basis in the normative data studies listed below.

IOL Calculator


  • comprehensive IOL planning
  • IOL calculation
  • documentation
  • constant optimization


Originally developed for the Pentacam® AXL, the IOL Calculator is now also available in the Pentacam® HR. It offers space for up to 25 ophthalmologists to maintain their own set of up to 50 favourite IOLs. A large IOL database has been incorporated into the software for this purpose. If an IOL should ever be found missing, it can be added manually. Each user initializes their personal IOL Calculator by picking IOLs from their favourites list. If no further changes are made and everything has been set up as desired, the user only needs to load an examination, and the software will automatically calculate IOLs suitable for that patient. In doing so it takes into account the keratometry data, the induced astigmatism and the target refraction. Templates for calculating spherical, aspherical, multifocal, toric and toric multifocal IOLs as well as post-refractive-surgery IOLS are included. In addition to the standard formulas of SRK/T, Haigis, HofferQ, Holladay and Barrett Universal II it also provides Pentacam®-specific post-refractive-surgery IOL formulas derived from dedicated studies. The well-known double K formulas and the three Barrett formulas have been incorporated here as well. But the real highlight in the IOL Calculator is its ability to calculate toric IOLs based on TCRP (total corneal refractive power) according to Dr. Savini. Toric IOL calculation according to Barrett is also in the repertoire. After surgery the implanted IOL can be loaded from t he templates and saved along with the date of surgery. After successfully entering the post-refractive outcome (≥ 30 days) the examination can be earmarked for constant optimization.

The software also provides interfaces for calculating IOLs with the Okulix and Phaco Optics raytracing programs as well as for incorporating further calculators such as the Holladay Consultant.

Belin/Ambrósio Display


  • Evaluating the corneal shape
  • Early detection of corneal changes


The Belin/Ambrósio Display is the first screening tool to combine anterior and posterior corneal elevation data with an evaluation of corneal thickness progression in a final parameter, referred to as Index D. Besides allowing for greater overall accuracy in evaluating corneal abnormalities it can, in particular, assist in the early detection of these. It determines the progression of corneal thickness across an array of concentric rings centered on the thinnest point and reaching into the periphery. Two elevation maps are generated, one based on a standard reference surface and the other on an enhanced reference surface, and the differences found between them are shown in a color code to facilitate evaluation: green for unremarkable, yellow for conspicuous, and red for potentially pathological.

Contact Lens Fitting


  • Automatic suggestions for contact lenses
  • Realistic fluo image simulation
  • Integrated database containing over 845,000 lenses


Dynamic fluo image simulation produces an image of how a specific contact lens from the database fits on the eye. The simulation makes it possible to adjust the inclination and position of the contact lens and includes automatic recalculation of the fluo image. The integrated and expandable database contains over 845,000 lenses. The contact lens geometries can be adjusted individually in cases where fitting is difficult. The user can establish his or her own ranking list for contact lens manufacturers.
