Official title
Agreement and Reproducibility of Intraocular Lens Tilt and Decentration Measurements: A Comparison Between CASIA2 and CILT
Overview
Agreement and Reproducibility of Intraocular Lens Tilt and Decentration Measurements: A Comparison between CASIA2 and CILT
Detailed description
This prospective observational study evaluates the agreement and reproducibility of intraocular lens (IOL) tilt and decentration measurements obtained from two different imaging modalities: the CASIA2 anterior segment swept-source optical coherence tomography (AS-SS-OCT) system and the Calculator for Intraocular Lens Tilt (CILT) software, based on standardized anterior segment image analysis.
Primary outcome measures
- Intraocular Lens Tilt (CASIA2 and CILT) [Time frame: Measured during the pre-surgery examination under normal pupil conditions and after pharmacologic dilation (45 minutes post-mydriatic instillation).]
- Intraocular Decentration (CASIA2 and CILT) [Time frame: Measured during the pre-surgery examination under normal pupil conditions and after pharmacologic dilation (45 minutes post-mydriatic instillation).]
