The Haag-Streit Lenstar LS-900 is a precision optical biometer designed for accurate eye measurements essential for cataract surgery planning and other ophthalmic procedures. It uses low-coherence optical reflectometry to provide precise measurements of axial length, corneal thickness, anterior chamber depth, and lens thickness.
Haag-Streit Lenstar LS-900 plays a crucial role in pre-operative planning by ensuring accurate intraocular lens power calculations, thereby enhancing surgical outcomes. It is integrated with software that facilitates data management and analysis, making it a valuable tool in modern ophthalmic practices.
The Lenstar is purpose-built for optometrists who want fast, highly accurate laser-optic measurements across every section of the eye—from the cornea to the retina. As the first optical biometer to measure crystalline lens thickness, Lenstar delivers advanced data for cataract and refractive surgery co-management.
With integrated Olsen formula and the optional Toric Planner (featuring the Barrett Toric Calculator), Lenstar gives optometrists access to the latest technology for precise IOL power prediction in every patient.
Features
LENSTAR® gives optometrists a complete biometrical assessment in one procedure, capturing seven key measurements:
- Pachymetry
- Lens Thickness
- Keratometry
- Pupillometry
- Axial Length
- ACD
- White to White
Dual-zone keratometry with 32 locations, or optional T-Cone topography, delivers reliable K values, axial length, and astigmatism assessments that optometrists need for advanced toric lens planning. The Lenstar LS 900 is the ideal platform for optometry clinics seeking superior refractive outcomes in cataract surgery—today and into the future.
Lenstar delivers precise, non-contact laser measurements from cornea to retina—including unique crystalline lens thickness data. This advanced biometer equips optometrists with the latest technology for accurate IOL prediction and confident surgical planning in modern optometric practices.
