Comparison of Outcomes With and Without Use of an Automatic Centration Feature

Abstract

Abstract: : Purpose: To compare the clinical outcomes of LASIK patients who underwent wavefront–guided ablation who were treated with the use of auto–centration software on the LADARWave aberrometer to those treated without. Methods: Prospective study in university based keratorefractive center with retrospective comparison. Results: Prospective clinical outcomes from LASIK patients treated with CustomCornea incorporating the new auto–centration feature on the LADARWave aberrometer were compared to a retrospective cohort of LASIK patients treated with CustomCornea prior to implementation of the new software feature. Standard outcome measures were compared between groups. In addition, preoperative and postoperative dilated wavefront measurements were used to compare aberrations for 25 patients in each group. Conclusions: The use of auto–centration features during CustomCornea treatment has been shown theoretically to improve the accuracy of wavefront registration, and in this study suggest that patient outcomes will be superior. Wavefront capture efficiency was also greatly enhanced.
