• Measures irregular astigmatism
• Determines if the optical aberration originates from the corneal surface or from an internal aberration such as from the lens.
• Provides more total eye refractive data for managing your patients including those whom may consider refractive surgery.
• Estimates the best corrected visual acuity
• Measures post operative eye values, which many standard auto refractometers can not measure accurately.
• Calculates estimated photopic and scotopic refractive results.
• Assists in the refractive measurements following a patient IOL implantation.

The KR-9000PW combines the most reliable wavefront measurement principles (Hartmann-Shack wave-front sensor and Zernike Polynomials) with our integrated Rotary Prism technology to deliver objective data that is unmatched in accuracy and reliability. The instrument provides sphere, cylinder and axis measurements as well as indicating spherical aberrations, coma and other high order aberrations of the eye. With a measuring range of -25 to +22 diopters of sphere, the new KR-9000PW is a practical wavefront tool for use in the everyday practice.

One of the important gains provided by successful wavefront-guided corrections occurs when the pupil dilates in photopic and scotopic conditions. The value of isolating the higher order data is an excellent way of determining if surgical intervention is appropriate. The KR-9000PW is the perfect compliment to laser treatment, allowing you to learn more about the high order issues that can lead to complications.
