The Lenstar LS 900 biometer is a non-invasive, non-contact OLCR (optical low-coherence reflectometry) biometer used for obtaining ocular measurements and performing calculations to assist in the determination of the appropriate power and type of IOL (intraocular lens) for implantation after removal of the natural crystalline lens. The LS 900 measures: • Axial eye length • Corneal thickness • Anterior chamber depth • Aqueous depth • Lens thickness • Corneal curvature • Radii
