Objectives: To compare central corneal topography (CT) obtained using the IOLMaster 700®biometer to corneal topography obtained using a Swept-Source OCT-based predicated topographer (PT), in candidates for toric intraocular lens (IOL) implantation. Methods: A retrospective comparative study was conducted in consecutive patients undergoing a routine cataract surgery assessment with significant astigmatism on keratometry. Each patient was examined using both the IOLMaster 700®(Carl Zeiss Meditec, Jena, Germany) and the Anterion®(Heidelberg Engineering, Heidelberg, Germany) for routine preoperative measurements. The corneal axial anterior power map obtained with each device was then anonymized and analysed independently by two ophthalmologists using a reading grid. The reading grid assessed the usual parameters describing astigmatism and evaluated if a toric IOL was indicated or a second topography examination was needed to confirm the indication. Results: In total, 169 eyes of 120 patients were included. The inter-examination agreement for the astigmatism description ranged from 56 to 85% depending on the reader and parameter. The decision to implant a toric IOL based on the axial map was the same in 59–60% of cases depending on the examiner. A second examination was needed in 18–25% and 8–14% of cases after CT and PT, respectively. The IOLMaster 700®central anterior axial map allowed toric IOL implantation in 58–70% of cases with no need for second corneal examination. Conclusion: The agreement between the anterior axial maps obtained using both devices was good. However, in about a quarter of the cases, dedicated topography had to be performed to confirm the surgical indication. |
