CUSTOMIZED MYOPIC LASIK TREATMENTS WITH THE INNOVEYES ARTIFICIAL INTELLIGENCE SOFTWARE BY ALCON: AN OBSERVATIONAL SINGLE-ARM CONSECUTIVE CASE SERIES

To evaluate the safety and efficacy of a novel automated ray-tracing optimization in customization of excimer ablation in myopic LASIK.

Observational consecutive case series; 20 consecutive myopic InnovEyes LASIK treatments (40 eyes).  All qualifying cases were treated with LASIK and the InnovEyes suggested low order (refraction) and high order aberrations.The ablation profile is initially calculated based on a 3D model eye for each case.  Optical coherence interferometry captures axial length data, and low and high order aberrations calculation is performed by ray-tracing based on wavefront and Scheimpflug tomography measurements, all from a single diagnostic device, InnovEyes sightmap. Visual Acuity, refractive error, keratometry, topography, high order aberrations and contrast sensitivity were evaluated, over six a month follow-up.

TBA X % of eyes gained one line of vision (UDVA post compared with CDVA pre) and X % 2 lines. Attempted vs. achieved correction was X(TBA) Diopters sphere and Xc(TBA) Diopters Cylinder. Pre- to post-operative high order aberrations average: RMSh changed from X um to X um. Contrast sensitivity changed from X(TBA) pre- to X(TBA) post-operatively.

We report safety and effectiveness preliminary outcomes with a novel excimer laser customization by ray tracing optimization, for myopic LASIK treatments, employing axial length, wavefront and corneal tomography measurements captured from one single device to produce a customized eye model reference for each case. It bears the potential advantage through total eye aberration data and ray tracing refraction calculation to offer improved and more predictable visual outcomes.
