MMLDs provide a light spectrum with a discrete pattern of individual wavelengths (Figure 1A). The Lenstar OLCR biometer utilizes a superluminescent diode (SLD) at 820 nm. In contrast to an MMLD, the spectrum of an SLD is continuous (Figure 1B).
TWO FUNDAMENTAL DIFFERENCES. Both PCI and OLCR are based on laser interferometry, first described by Albert Abraham Michelson.1 But PCI and OLCR differ in two fundamental details: their light sources and the optical setup of their interferometers.
The Lenstar (Haag-Streit AG, Koeniz, Switzerland) is a new noncontact imaging instrument using optical low-coherence reflectometry (OLCR) powered by a superluminescent diode (SLD) to measure AL, ACD, central corneal thickness (CCT), lens thickness (LT), and corneal curvature.
Aug 1, 2020 · Purpose: 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...
Jul 22, 2014 · Purpose: To compare the ability of two optical biometers to acquire the axial length (AL) measurement in cataractous eyes. Methods: This prospective, comparative, single-center study comprised 105...
Feb 24, 2017 · The Lenstar (Haag-Streit, Koeniz, Switzerland), a more recent biometer to the market, has been the first competitor of the IOLMaster. It uses optical low-coherence reflectometry (OLCR) with a 820...
