Keratograph® 4

It ensures reliability when it comes to taking measurements, providing consultation and fitting contact lenses. The Keratograph® accurate findings are something you can count on.

The integrated keratometer and automatic measurement activation guarantee perfect reproducibility.

In this way the Keratograph® 4 also meets highest clinical standards for such procedures as tear film assessment and qualitative cornea analysis. It stands out by virtue of its versatility.

A Picture Says More Than 1,000 Words

Use the Keratograph® 4 as a marketing tool and incorporate it actively into your consultations. With the Keratograph® 4 software you can show images which your clients/patients have never seen before.

Contact Lens Fitting and Fluorescein Image Simulation

Contact lenses are recommended on an individual basis and displayed in a list. In order to avoid taking more steps than necessary when fitting contact lenses, the fluorescein image can be simulated beforehand. The contact lens can be rotated and moved around. Fluorescein image simulation is adjusted automatically. The integrated and expandable database contains all customary types of contact lenses and is updated on a regular basis. The user can determine the order in which contact lens manufacturers appear.

OxiMap® – Visualizing the Oxygen Transmissibility

Professional patient consultation

The cornea needs oxygen and a good oxygen supply is fundamental for the comfort of a contact lens wearer. New materialsused for soft contact lenses offer excellent oxygen transmissibility. This can be shown with the new OCULUS OxiMap® display. You can easily show these color maps to your patients and help them choose better contact lenses.

TF-Scan Makes the Tear Film Visible

This software shows the quality and quantity of the tear film.

In cases of dry eye patients and contact lens wearers, the tear film should be examined carefully. Only an intact tear film guarantees contact lens wearing comfort! The Keratograph® 4 measures the tear film breakup time non-invasively (quality assessment). You can show your patient the individual tear film quality using the color maps and by taking anothe

Software

TF-Scan Makes the Tear Film Visible

Patient consultation made easy. This software shows the quality and quantity of the tear film.

In cases of dry eye patients and contact lens wearers, the tear film should be examined carefully. Only an intact tear film guarantees contact lens wearing comfort! The Keratograph® 4 measures the tear film breakup time non-invasively (quality assessment). You can show your patient the individual tear film quality using the color maps. In addition, you can take another non-invasive measurement to determine the amount of tear film (tear film quantity).

Tear Film Quality (NIKBUT)

The OCULUS Keratograph® 4 determines the break-up time using the NIKBUT procedure (non-invasive-Keratograph-break-up time).

Pupillometry

Using the “Pupillometry” option, the reaction of the pupil, can be checked with and without blinding. This builds the basis for selecting the proper treatment zone for laser controlled surface ablation, multifocal contact lenses or premium IOLs. The pupil reaction of the two eyes can be compared.

Optional Imaging-Software*

The Imaging-Software takes real-time fluo-images or fluo-clips of the contact lens. The high resolution clip shows the movements of the contact lens on the cornea. A side-by-side comparison displays the simulated fluo image of the software and the real time fluo image and the clip.

Essential for:

  • Demonstration of the fit and mobility of contact lenses
  • Assessment of the static fluo-image
  • Assessment of the fit of the contact lenses with different pupil diameters
  • Side-by-side comparison of fluo-image simulations to real-time fluo-images
  • Choice of the final contact lense
  • Expertise and customer long term relationship

OCULUS OxiMap®

The OxiMap® presents a color map of the oxygen transmissibility of soft contact lenses based on the lens power, which is easy to understand – even for your customers!
