Details
This software provides a standardized method of selective quantification of corneal opacities. The maximum and average corneal opacity is displayed in a colour 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.

Belin/Ambrósio Enhanced Ectasia Display
Uses
- Early ectasia detection
- Reliable detection of forme-fruste keratoconus
Details
The Belin/Ambrósio Enhanced Ectasia 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 diagnosing ectasia it can in particular assist in the early detection of this disorder. 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 colour code to facilitate evaluation: green for unremarkable, yellow for conspicuous, and red for potentially pathological.

New
CSP Report Pro
CSP Report Pro: Single-Shot Topography for Efficient & Convenient Scleral Lens Fittings
The new single-scan Scheimpflug technology of the CSP Report Pro can achieve extensive coverage in one acquisition, though practitioners can take as few or as many scans needed to capture optimal data while focusing on patient comfort. It captures topographic measurement of the cornea, sclera, and sagittal height. For patients and eye care professionals, the CSP Report Pro enables an easier process for fitting scleral and corneal lenses of every type and diameter.
The CSP Report Pro is integrated as part of the examination routine, which guides the user through the imaging process. Since neither the patient nor the device need to be repositioned, the intuitive guide enables fast examination of both eyes within just a few minutes.
Enjoy a patient-friendly imaging process since the CSP Report Pro measurement is fast, non-contact, and doesn’t require fluorescein. Practitioners also benefit because the measurement process is user-independent, reliable, straightforward, and tear film-independent.
Contact Lens Fitting incl. fourier analysis
Uses
- Automatic suggestions for contact lenses
- Realistic fluo image simulation
- Integrated database containing over 845,000 lenses
Details
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.
IOL Calculator
Uses
- comprehensive IOL planning
- IOL calculation
- documentation
- constant optimization
Details
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 the 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.
Holladay Report
Uses
- Comprehensive comparative display of clinical data
- EKRs (equivalent keratometer readings) for IOL calculations in post-refractive patients
Details
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.

3D pIOL Simulation and Aging Prediction
Uses
- Pre-surgical planning of an iris-supported phakic anterior chamber lens
- Simulation of the post-operative position of the phakic anterior chamber lens
- Simulation of age-related lens growth and the position of the anterior chamber lens resulting from this
Details
The examiner enters the data on the patient's subjective refraction. Depending on the type of lens in question, the software calculates the necessary refractive power of the pIOL. The examiner selects a phakic IOL from the current database accordingly. The position of this pIOL in the anterior chamber is calculated in 3D and displayed in Scheimpflug images. The minimal distances between the phakic IOL and the crystalline lens as well as between the pIOL and the endothelium are calculated automatically and represented both in colour and numerically. This enables the examiner to give the patient visual information and facilitates patient selection.
