Comparison of Central Corneal Thickness using Anterior Segment Optical Coherence Tomography Versus Ultrasound Pachymetry [PDF]

Journal of Clinical and Diagnostic Research, 2017
Introduction: Corneal thickness is an important and sensitive indicator of corneal health. It is useful in monitoring corneal diseases such as corneal oedema and keratoconus, and selecting patients for refractive surgery.

Coupled Biomechanical Response of the Cornea Assessed by Non-Contact Tonometry. A Simulation Study [PDF]

, 2015
The mechanical response of the cornea subjected to a non-contact air-jet tonometry diagnostic test represents an interplay between its geometry, the corneal material behavior and the loading.

Immediate Postoperative Decentration of a Biologic Corneal Inlay Managed With Tomography-Guided Repositioning: A Case Report. [PDF]

Clin Case Rep
Immediate postoperative Pentacam corneal tomography revealing inferior‐temporal decentration of the biologic corneal inlay on the axial curvature map. ABSTRACT Biologic corneal inlays can rarely present with immediate postoperative decentration, which can be subtle and difficult to detect clinically. Real‐time tomography allows precise early diagnosis,
