Department of Ophthalmology, University of California San Francisco, San Francisco, CA, USA.
Purpose: To compare the outcomes of two different surgical planning strategies for topography-guided repair of post-LASIK ectasia.
Methods: This is a case report of a patient presenting with post-LASIK ectasia. A retrospective chart review was used to collect details of the ophthalmic exam, as well as ocular imaging such as anterior segment optical coherence tomography and Scheimpflug corneal tomography.
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.
[Comparison of visual outcomes between corneal topography-guided FS-LASIK and SMILE for myopia and myopic astigmatism: a network meta-analysis].

To compare the postoperative visual outcomes of corneal topography-guided femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) and small incision lenticule extraction (SMILE) for myopia and myopic astigmatism. Embase and PubMed were searched for randomized controlled trials (RCTs), prospective comparative studies, observational studies and retrospective studies of patients with myopia and/or myopic astigmatism treated by corneal topography-guided FS-LASIK, the other FS-LASIKs or SMILE (inception to November 2023). The studies meeting the criteria were collected and underwent quality assessment according to the Jadad scale for RCTs and the Newcastle-Ottawa scale for non-randomized studies.

Cornea Revolution/Motwani LASIK Institute, San Diego, CA, 92121, USA.
Purpose: To present the outcomes of a retrospective study of treatment of radial keratotomy-induced corneal irregularity with topographic guided ablation and a trans-epithelial approach based on epithelial compensation.
Methods: Sixty eyes of 31 patients were treated for radial keratotomy-induced corneal irregularity utilizing a customized trans-epithelial topographic guided ablation photorefractive keratectomy (PRK) for treatment of corneal higher-order aberrations and lower-order astigmatism. Three-month results were analyzed via measurement of vision, refraction, residual higher-order aberrations (HOAs), residual lower-order and higher-order aberrations, as well as for loss or gains of lines of best corrected visual acuity.
Purpose: To report 12-month visual and refractive outcomes following topography-guided femtosecond laser-assisted laser in situ keratomileusis (LASIK) for myopia and compound myopic astigmatism correction.
Methods: This prospective, single-center observational study was conducted in an outpatient clinical practice at the Stanford University Byers Eye Institute in Palo Alto, California. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, 5% and 25% contrast sensitivity CDVA, and manifest refraction following topography-guided femtosecond laser-assisted LASIK were assessed.
