Pentacam®

For a High-Level Entry

The Pentacam® provides you with an overall view of the anterior eye segment in a matter of seconds. Measurements are performed by auto-release and are accompanied by a quality test, thus guaranteed to be fast, reproducible and delegable.

The Pentacam® comes with an extensive basic software package which can be extended according to your needs to include further optional software packages and modules.

Pentacam® 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.

Cataract Pre-OP Display

Cataract Pre-OP Display was developed in collaboration with Prof. Dr. Naoyuki Maeda from the University Medical School in Osaka, Japan. This display assists users in selecting the optimal premium IOL.

To do this, the following parameters are taken into consideration:

  1. overall corneal astigmatism,
  2. total corneal spherical aberrations,
  3. total corneal irregularities and
  4. the influence of the posterior corneal surface.

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.
