Purpose To evaluate the performance of the InnovEyes Sightmap platform (Alcon Laboratories, Inc) in refractive surgery by comparing the visual acuity and higher order aberrations (HOAs) between ray-tracing–guided laser in situ keratomileusis (LASIK) and topography-guided LASIK. Methods This prospective study enrolled participants who underwent either ray-tracing–guided LASIK or topography-guided LASIK. Comprehensive ophthalmic evaluations were performed preoperatively, as well as at 1 day, 2 weeks, 1 month, and 3 months postoperatively. Patients in the ray-tracing–guided LASIK group underwent wavefront, tomography, and biometry assessment using the InnovEyes Sightmap diagnostic device. Assessments included visual acuity, manifest refraction, and whole-eye HOAs. Results A total of 42 eyes treated with ray-tracing–guided LASIK and 42 eyes treated with topography-guided LASIK were analyzed. Both strategies demonstrated comparable good refraction accuracy and refractive stability ( P > .05). The ray-tracing–guided LASIK group exhibited significantly better postoperative uncorrected distance visual acuity (UDVA) compared to the topography-guided LASIK group (−0.12 ± 0.05 vs −0.07 ± 0.04 logarithm of the minimum angle of resolution, respectively; P < .05), with 48% of eyes achieving a UDVA of 20/12.5 or better. Ray-tracing–guided LASIK induced a small but statistically significant increase in HOAs and vertical coma aberration, along with a significant reduction in spherical a...
