Article Synopsis
  • The study aimed to enhance the detection of corneal ectasia susceptibility using tomographic data collected from multiple clinics across South America, the U.S., and Europe.
  • Researchers developed AI models using Pentacam HR parameters to analyze preoperative data from different patient groups, including stable LASIK cases, those with post-LASIK ectasia, and patients with keratoconus.
  • The newly created Pentacam Random Forest Index (PRFI) showed superior accuracy in diagnosing ectasia compared to existing methods, suggesting that incorporating more corneal biomechanical data could further improve risk assessment.

Purpose: To critically evaluate the following clinical wisdom regarding custom (wavefront-guided) laser in situ keratomileusis (LASIK) that subjects with better-than-average best-corrected visual acuity (BCVA) before surgery have a greater risk of losing BCVA postoperatively than do subjects with worse-than-average BCVA before surgery.

Methods: High contrast BCVA was measured once before and 3 months after custom LASIK in one eye of 79 subjects. Preoperative spherical equivalent refractive error ranged between -1.

Purpose: To compare preoperative and postoperative changes in simulated night driving performance after wavefront-guided (wLASIK) and conventional LASIK (cLASIK) for the treatment of moderate myopia.

Design: Retrospective, comparative study.

Participants: All eyes of subjects with a preoperative manifest spherical equivalent (MSE) between -4.
