    Comparison of Optical Low-Coherence Reflectometry and Swept-Source OCT–Based Biometry Devices in Dense Cataracts

    To investigate agreement between biometric measurements obtained from the Lenstar LS 900 (Haag-Streit AG) based on optical low-coherence reflectometry (OLCR) and the Tomey OA-2000 (Tomey Corporation) based on swept-source optical coherence tomography (SS-OCT) in dense cataracts. METHODS: In this prospective observational study, axial length, keratometry, anterior chamber depth (ACD), lens thickness, and central corneal thickness (CCT) were measured in 124 eyes of 76 patients. Intraocular lens prediction errors and absolute prediction errors were assessed based on postoperative manifest refraction. Analyses used were paired t test, Pearson correlation coefficient ( r ), and Bland-Altman plots. RESULTS: Failure in axial length measurements was noted ...
