The LENSTAR LS 900 APS (Automatic Positioning System) is an advanced optical biometry system that uses Optical Low-Coherence Reflectometry (OLCR) technology. It provides highly precise measurements of the entire eye, from the cornea to the retina.

Unlike ultrasound biometry, the LENSTAR performs non-contact measurements, improving patient comfort and reducing infection risk. The APS technology ensures automatic alignment, making measurements faster and more consistent.

The device measures:

  • Axial length
  • Keratometry (corneal curvature)
  • Anterior chamber depth
  • Lens thickness
  • Central corneal thickness
  • White-to-white distance

These parameters are essential for accurate intraocular lens (IOL) calculation and premium IOL planning.

The LENSTAR LS 900 APS integrates modern IOL calculation formulas and supports advanced cataract workflows, helping surgeons achieve predictable refractive outcomes.
