Bilateral Comparison of Conventional Versus Topographic-guided Customized Ablation for Myopic LASIK With the NIDEK EC-5000

Journal of Refractive Surgery, 2006
ABSTRACT PURPOSE: To compare visual acuity and higher order aberrations before and after myopic LASIK using conventional versus customized ablation. METHODS: This prospective, randomized study included 54 myopic eyes in 27 patients who underwent bilateral LASIK using the NIDEK EC-5000 excimer laser system (NIDEK Technologies ...

Refractive and Topographic Errors in Topography-guided Ablation Produced by Epithelial Compensation Predicted by 3D Artemis VHF Digital Ultrasound Stromal and Epithelial Thickness Mapping

Journal of Refractive Surgery, 2012
PURPOSE: To describe and quantify the errors inherent to topography-guided ablation of irregular corneas due to natural epithelial thickness compensatory remodeling. METHODS: Artemis very high-frequency (VHF) digital ultrasound scanning (ArcScan Inc) was performed on a cornea that ...

Topographic- and Wavefront-guided Customized Ablations With the NIDEK-EC5000CXII in LASIK for Myopia

Journal of Refractive Surgery, 2006
ABSTRACT PURPOSE: To assess refractive outcomes, changes in the total higher order root mean square (RMS) aberration, and changes in higher order wavefront aberrations after LASIK for myopia and myopic astigmatism with the NIDEK Advanced Vision Excimer Laser platform (NAVEX) using either an aspheric or topography-based or whole eye wavefront ...

Corneal topograph-guided laser subepithelial keratomileusis (LASEK) corrects decentered ablation after laser in situ.

Eye science, 2015
Corneal topograph-guided laser subepithelial keratomileusis (LASEK) can effectively correct decentered ablation occurring post laser in situ keratomileusis (LASIK) and to enhance our understanding and diagnosis of decentered ablation following LASIK.Previous studies in the relevant literature are reviewed, and a case report is provided.A patient with ...
