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.

Clinical Applications for Optometrists
- Cataract surgery IOL calculation: Perform comprehensive 9-parameter biometric workups to support accurate IOL selection and surgical planning in the optometry clinic.
- Premium IOL planning: Assess toric, multifocal, and EDOF IOL candidates using advanced biometric data to provide confident recommendations and referrals.
- Post-LASIK/refractive cataract: Achieve high-accuracy axial length measurements even in eyes with corneal modifications, supporting complex case management in optometry clinics.
- Pediatric cataract: Use non-contact OLCR technology to measure young patients accurately and comfortably, eliminating the need for contact ultrasound and reducing exam anxiety.
- Pre-op planning and research: Access Hill-RBF and Barrett formulas for advanced surgical planning and evidence-based co-management.
- Dense cataract biometry: Obtain reliable measurements even through media opacities where ultrasound may fail—improving efficiency and patient outcomes in challenging cases.
Who Benefits in Optometry
- Optometry clinics and co-management practices performing daily IOL calculations and cataract assessments.
- Optometry practices supporting premium IOL procedures—including toric, multifocal, and EDOF lens planning and referrals.
- Optometrists and surgical partners managing post-LASIK and complex refractive cataract biometry cases.
- Multi-optometrist clinics standardizing on Haag-Streit + EyeSuite workflow for consistent, efficient biometry across the practice.
- Optometrists comparing Lenstar LS-900, Zeiss IOLMaster, and Nidek AL-Scan for advanced biometry and workflow integration in their clinic.
