With its brighter and optimized optics the Pentacam® HR offers you brilliant image quality.
The resolution of its images is five times that of the Pentacam® models, enabling the Pentacam® HR to deliver impressive representations of IOLs and phakic IOLs.
The Pentacam® HR comes with an extensive basic software package which can be extended according to your needs to include further optional software packages and modules.
Pentacam® HR Basic Software
- 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 colour maps.
Fast Screening Report
- Quick detection of irregularities
- Patient consultation
The Fast Screening Report provides a quick and simple overview that allows detection of irregularities in the anterior eye segment. Further displays for evaluating such irregularities in detail can be accessed via the navigation bar. Parameters are displayed against their normal distribution in healthy (green) as well as affected (red) populations as reported in published studies. The publication used in each case is identified under “Literature”. This display does not purport to give any kind of diagnosis. Diagnoses are the sole responsibility of the ophthalmologist and must be based on the entirety of information available.
Belin/Ambrósio Enhanced Ectasia Display
- Early ectasia detection
- Reliable detection of forme-fruste keratoconus
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.

- 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 Progression Display
- Keratoconus 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 keratoconus, the green lines the normal/healthy group. The solid lines indicate the 95 % CI and the dashed lines the 80 % CI. The Belin ABCD Keratoconus Staging (Topometric/KC-Staging) and the Belin ABCD Progression Display can be used retrospectively.
- 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.
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.
Scheimpflug Image Overview
- Check after scan abortion 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). It can reveal first signs of opacification of the cornea or crystalline lens.
The display is also useful for detecting first signs of opacification of the cornea or crystalline lens.
