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.

Evaluation of Transparency and Barrier Function of the Cornea by Scheimpflug Images

Ophthalmic Research, 2009
Two new methods of corneal analysis with Scheimpflug images will be introduced in this paper. The first study was to document the light scattering of the cornea itself using a newly modified Scheimpflug camera with higher magnification. Details of the slit images of the cornea could be evaluated more precisely than those of images taken with an ...

Evaluation of parameters for early detection of pediatric keratoconus

BMC Ophthalmology
Background Keratoconus in children is often more severe and rapidly progressive compared to adults. While Scheimpflug imaging (Pentacam) improves screening, there are no established pediatric guidelines.
