Auto-keratometer refractometer AKR 500

The Essilor AKR 500 Auto-Keratometer Refractometer - Exceptional precision in refraction and keratometry measurements.

This precision is made possible by its unique and patented rotating prism technology. This innovation allows for extremely precise measurements, making it a preferred tool for eye health professionals seeking reliable results.

One remarkable feature of the AKR 500 is its ability to measure pupils as small as 2 mm, making it an ideal choice for patients with specific eye conditions such as glaucoma, asymmetric pupils, or age-related retinal pathologies. Pupil size measurement can also be performed under scotopic and photopic lighting conditions, ensuring accurate results in various environments.

Operation of the AKR 500 is fast, easy, and stress-free, particularly in burst mode. Additionally, its compact optical head improves interaction with the patient and visibility of their position, contributing to a pleasant experience for the patient.

It is also ready for integration into an automated refraction chain. It can be connected to the Essilor APH 500 automatic refractor for automatic transmission of objective refraction data. This simplifies workflow and enhances the efficiency of eye health professionals.
