Pentacam® HR

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 Optional software modules

New
CSP Report

Uses

  • Display of sagittal heights of cornea and sclera
  • Profile of sclera for scleral lens fitting

Details

With the CSP Report, the Pentacam® now measures sagittal height, a parameter needed for scleral lens fitting. 250 Scheimpflug images covering a diameter of up to 18 mm are taken in the measuring process. All images of a Cornea Scleral Profile (CSP) scan are taken from the same visual axis without the need for eye movement. The usual Pentacam® data are recorded as well and populated into the displays already familiar to Pentacam® users. The CSP scan is a tear film independent measurement with automatic release. This means that the values from the CSP Report are as reproducible as all other data measured with the Pentacam®. A link to external fitting software for scleral lenses is available.

Corneal Optical Densitometry

Uses

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

Details

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.

PNS and 3D Cataract Analysis

Uses

  • Cataract classification
  • Determination of lens opacities in 3D

Details

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.

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.
