Intraocular lens alignment from Purkinje and Scheimpflug imaging [PDF]

Clinical and Experimental Optometry, 2010
The improved designs of intraocular lenses (IOLs) implanted during cataract surgery demand understanding of the possible effects of lens misalignment on optical performance. In this review, we describe the implementation, set-up and validation of two methods to measure in vivo tilt and decentration of IOLs, one based on Purkinje imaging and the other ...

Immediate Postoperative Decentration of a Biologic Corneal Inlay Managed With Tomography‐Guided Repositioning: A Case Report

Clinical Case Reports, Volume 14, Issue 3, March 2026.
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,

A review of angle kappa and multifocal intraocular lenses and their effect on visual outcomes

Acta Ophthalmologica, Volume 104, Issue 2, Page e122-e138, March 2026.
Abstract Although most patients are satisfied with their vision after multifocal intraocular lens (IOL) implantation, dissatisfaction has been reported for various reasons, including poor visual outcomes and visual disturbances. Many published reports hypothesise that preoperative angle kappa may be an associated factor in patient dissatisfaction ...

Comparative Study of Anterior Chamber Morphometrics Between Scheimpflug Tomography and Swept‐Source Optical Coherence Tomography

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare the difference, correlation, and agreement of anterior chamber parameters measured by Pentacam and CASIA 2. Methods A total of 89 myopic patients (89 right eyes) of Beijing Tongren Hospital were included. Anterior chamber depth (ACD), anterior chamber volume (ACV), and anterior chamber angle (ACA) were measured by Pentacam and CASIA ...
