Imaging in Cataract Surgery
Abstract
Overview
With increased patient expectations for precise post-operative refractive results, the need for accurate keratometry, biometry, and appropriate intraocular lens power formula selection is of paramount importance. The past decade has brought improvements in topography, biometry, and intraocular lens (IOL) calculations and the advent of intra-operative imaging and aberrometry has assisted in achieving more accurate post-surgical refractive outcomes. This review aims to provide an overview of imaging modalities used in the pre-operative and intra-operative setting in anterior segment cataract surgery. Intraoperative imaging can be used in: capsulorhexis centration, wound and astigmatic keratometry placement, IOL centration and toric alignment. Specifically, we aim to provide an overview on the Zeiss Callisto® (Zeiss, Oberkochen, Germany) imaging system used in toric lens alignment, the Alcon Verion (Alcon, Fort Worth, Texas, USA) used in combination with the ORA SystemTM (WaveTec Vision, Aliso Viejo, California, USA) for toric lens alignment and intraoperative aberrometry for lens selections, and the TrueVision 3D System (TrueVision 3D Surgical, Goleta, CA, USA) used in toric lens alignment. The utility of intraoperative imaging in correcting astigmatism and selecting IOL powers in routine cataract surgery remains an adjuvant to current pre-operative keratometry and biometry. Although studies have shown effectiveness of utilising intraoperative imaging in cataract surgery, there remains a need for larger retrospective studies that compare the accuracy of current IOL formulas versus intraoperative aberrometry
in both normal and post-refractive surgery.
