Abstract
Purpose: To describe recent technological additions to the NIDEK CXIII and Quest excimer lasers. Methods: A summary article with data from previous published studies outlining the benefits of newer technology. Results: The addition of a 1-kHz infrared eye tracker decreased the spread of laser spot placement from a mean of 228.79 µm without a tracker to 38.47 µm with the eye tracker. The addition of real-time torsion error correction produced a statistically significantly lower cylinder dispersion, mean manifest refractive cylinder, and error of angle postoperatively in eyes that underwent LASIK. Conclusions: The incorporation of an ultrahigh speed eye tracker and active cyclotorsion correction surpasses the minimal technology criteria required for accurate wavefront-based ablations.
