Wave-Front Analyzer KR-1W

Perfection for Professionals : KR-1W

Topcon, with its wealth of experience in designing and manufacturing refractometers and other diagnostic equipment for over 50 years, introduces a new diagnostic tool with 5 functions to support the evaluation of the visual performance of the human eye. The KR-1W combines aberrometry, topography, keratometry, pupillometry and autorefraction in one unit that is unparalleled in terms of functionality and reproducibility. At the same time the KR-1W is extremely easy to operate and allows fast patient throughput.
The KR-1W will become the professional’s choice for comprehensive diagnosis of many ocular conditions.

Features

  • 5 functions in 1 machine:
    (Auto-Refraction, Keratometry, Aberrometry, Topography and Pupillometry)
  • Multiple maps for overview analysis
  • Decision support for cataract and refractive procedures
  • Less stress with invisible light measurement at topography
  • Easier operation with R / L fully automated measurement and touch panel

A Picture Says More Than a Thousand Words

The multiple maps provide helpful insight for refractive procedures that are done on the corneal surface or intraocularly. It allows an objective quality control of the surgical procedures.

IOL Selection

Important factors in making the right IOL selection for your patient at one glance.

1. Corneal Higher Order Aberration Index
This index provides information on the potential visual outcome considering the aberration that cannot be corrected by an IOL.
Additional treatments, i.e. contact lens fitting or corneal surface treatments, might be necessary to optimize the outcome.
2. Post Refractive Surgery Index
This index provides information on corneal irregularities possibly caused by previous surface treatments of the cornea. This might lead to the necessity of calculating the power of the IOL with non-standard formulas with special attention.
3. Corneal Spherical Aberration Index
This index provides very useful information on the asphericity of the cornea. This gives you the opportunity to select the right monofocal IOL to compensate for the spherical aberration of the patients' cornea.
4. Corneal Astigmatism Index
This simple display of corneal astigmatism provides information for two important decisions.
  • Amount of toric correction needed in a toric IOL
  • Patients with a high corneal astigmatism might not be the right candidate for a multifocal IOL

5. Review After Toric IOL Implantation
The result after implantation can be reviewed to check residual ocular astigmatism.

Pupillometry

Screening application to evaluate eyes for multiforcal IOL implantation or refractive surgery.

Corneal Refractive Surgery
For any refractive procedure it is vitally important to diagnose the pupil very carefully in different light conditions.
Also for refractive surgery this tool gives you the necessary information to plan your treatment.
Dynamic Pupil Diameter Measurement and Pupil Center Determination
This information is very important for premium IOL implantation, as it will give you the possibility to select the right multifocal IOL design for the individual eye and also help exclude extreme cases of pupil decentration before surgery.

The index of Ocular Total Higher Order aberration, refraction data are provided in photopic and scotopic condition.

Continuous Measurement Function
Up to 10 measurements can be done continuously to observe the change in ocular HOA during about 10 seconds.
This may have implication for dry eye diagnosis in the future.
