We thank Dr. Motwani for his interest in our study. While he mentions a second study that follows the same “script”, we would point out that data from our practice was not included in that study. The similarity appears related to the fact that both studies were retrospective, where data are limited and the outcome measures are patient-based, generally consisting of the postoperative refraction and visual acuity data in the clinical records. Our primary goal was merely to determine if use of the Phorcides Analytical Engine (Phorcides) was improving outcomes in our practice. 
We do not believe LYRA was mischaracterized in the manuscript, as the comment (reworded and slightly less clear in Dr. Motwani’s letter) was meant only to indicate that both topographic and refractive data were being used to plan the laser treatment.
