High-resolution, wavefront-guided treatment aids night vision

October 15, 2004

San Diego-Wavefront-guided treatments seem to improve night-vision disturbances caused by LASIK. Patients with severe higher-order aberrations after the initial refractive procedure benefitted from treatment driven by the Wavefront Aberration Supported Corneal Ablation (WASCA) aberrometer and the MEL-80 excimer laser driven by the CRS-Master software platform (all from Carl Zeiss Meditec AG).

During the annual meeting of the American Society of Cataract and Refractive Surgery, he spoke about the accuracy of a vision-correction system that included the WASCA aberrometer, the CRS-Master, the MEL-80 excimer laser, and the Artemis 2 (Ultralink LCC), a very high-frequency (VHF) digital ultrasound arc scanner.

"The WASCA aberrometer is the highest-resolution wavefront sensor available," he said. "It provides a higher dynamic range, higher (degree of) accuracy, and higher (degree of) reproducibility than other competing aberrometers.
