Objective: In recent years wavefront technology has been applied to human vision promising supernormal vision and better visual performance by correcting the eye’s higher order aberrations. Wavefront treatment of the human eye has been introduced in wavefront-guided refractive surgery. Since higher order aberrations change over time there is a need for higher order spectacle correction to compensate for these changes in ocular optics. In the present paper a novel aberrometer (Zview^TM, CA) for the measurement, diagnosis and prescription of corrective lenses for patients with higher-order aberrations will be presented.
Methods: The device is a binocular wavefront aberrometer incorporating a new grating-based wavefront sensor and stands in contrast to conventional Hartman-Shack technology. The proposed technique combines standard refraction with wavefront technology to create customized spectacle lenses. The eye is measured objectively with the aberrometer, the data are processed, and then the lens is produced according to the wavefront pattern. The new lens contains all-low-order correction, and correction from the 3^rd to 6^th higher order aberrations, and is thus a totally customized, one-of-a-kind match to the eye’s individual fingerprint.
Conclusions: With the introduction of wavefront technology in spectacle lens correction a dramatic improvement in visual quality can be expected in the future.
