Comparative Topographic and Tomographic Assessment of Post‐LASIK Corneal Ectasia

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To evaluate and compare the topographic and tomographic characteristics of post–laser in situ keratomileusis (LASIK) ectasia (PLE) with keratoconus (KC) and normal control eyes using the Sirius imaging system. Methods This comparative cross‐sectional study included eyes with KC, PLE ectasia, and normal control eyes.
