ZEISS IOLMaster 700 is a state‑of‑the‑art optical biometer developed by Carl Zeiss Meditec AG that uses Swept‑Source OCT biometry to capture precise ocular measurements and a full‑length OCT scan from cornea to retina. It provides all key biometric data needed for modern IOL power calculation (including axial length, keratometry, lens and corneal thickness) and supports technologies like Total Keratometry (TK®) to include posterior corneal curvature for improved refractive outcomes. Integrated into advanced cataract workflow solutions, the IOLMaster 700 helps optimise surgical planning, reduce refractive surprises and enables features such as markerless toric IOL alignment when used with compatible systems.
