简要总结
Agreement and Reproducibility of Intraocular Lens Tilt and Decentration Measurements: A Comparison between CASIA2 and CILT
详细描述
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.

结局指标
主要结局
Intraocular Lens Tilt (CASIA2 and CILT)
时间窗: Measured during the pre-surgery examination under normal pupil conditions and after pharmacologic dilation (45 minutes post-mydriatic instillation).
Intraocular lens (IOL) tilt, measured in degrees, assessed from anterior segment swept-source optical coherence tomography (AS-SS-OCT) images using the CASIA2 system and CILT software. Tilt is defined as the angle between the IOL plane and the corneal vertex.
Intraocular Decentration (CASIA2 and CILT)
时间窗: Measured during the pre-surgery examination under normal pupil conditions and after pharmacologic dilation (45 minutes post-mydriatic instillation).
Intraocular lens (IOL) decentration, measured in micrometers, assessed from anterior segment swept-source optical coherence tomography (AS-SS-OCT) images using the CASIA2 system and CILT software. Decentration is defined as the distance between the IOL center and the corneal vertex.
