Intended Use

The LENSTAR LS 900 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 following cataract removal. The LENSTAR LS 900 measures: - Axial eye length . - . Corneal thickness - . Anterior chamber depth - . Aqueous depth - . Lens thickness - Radii of curvature of flat and steep meridian . - Axis of the flat meridian . - White to white distance - . Pupil diameter

Device Story

LENSTAR LS 900 is non-invasive, non-contact Optical Low Coherence Reflectometry (OLCR) biometer; used in clinical settings by eye care professionals. Device captures ocular measurements including axial length, corneal thickness, anterior chamber depth, aqueous depth, lens thickness, corneal curvature radii, flat meridian axis, white-to-white distance, and pupil diameter. System processes these inputs to perform calculations assisting physicians in determining appropriate IOL power and type for post-cataract surgery implantation. Output provided to clinician to guide surgical planning and IOL selection; facilitates accurate lens power determination, potentially improving patient visual outcomes post-cataract removal.

Clinical Evidence

Two prospective, non-randomized, single-site comparison studies conducted in Berne, Switzerland. Evaluated axial length, central corneal pachymetry, anterior chamber depth, central lens thickness, average corneal radius, flat corneal axis, white-to-white distance, and pupillometry. Study results substantiated equivalence between LENSTAR LS 900 measurement data and predicate devices (IOL-Master, OLCR, Accusonic A-Scan, and Keratron).

Technological Characteristics

Non-invasive, non-contact OLCR biometer. Measures ocular parameters via optical low coherence reflectometry. Standalone system for clinical use. No specific materials or software architecture details provided.

Indications for Use

Indicated for patients undergoing cataract surgery requiring ocular measurements and IOL power/type calculations for intraocular lens implantation.

Regulatory Classification

Identification

An AC-powered slitlamp biomicroscope is an AC-powered device that is a microscope intended for use in eye examination that projects into a patient's eye through a control diaphragm a thin, intense beam of light.

Special Controls

*Classification.* Class II (special controls). The device, when it is intended only for the visual examination of the anterior segment of the eye, is classified as Group 1 per FDA-recognized consensus standard ANSI Z80.36, does not provide any quantitative output, and is not intended for screening or automated diagnostic indications, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 886.9.

### GENERAL DEVICE DESCRIPTION

The LENSTAR LS 900 is a non-invasive, non-contact system for measuring the parameters of the human eye required to determine the appropriate IOL for implantation and to calculate the optimal power of the IOL. The LENSTAR LS 900 measures: axial eye length, corneal thickness, anterior chamber depth, lens thickness, radii of curvature of flat and steep meridian, axis of flat or step meridian, white to white distance and pupil diameter.

### INDICATIONS FOR USE

The LENSTAR LS 900 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 following cataract removal. The LENSTAR LS 900 measures:

- Axial eye length b
- ë Corneal thickness
- Anterior chamber depth も
- � Aqueous depth
- Lens thickness .
- Radii of curvature of flat and steep meridian �
- � Axis of the flat meridian
- White to white distance .
- Pupil diameter .

# SUMMARY OF TECHNOLOGICAL CHARACTERISTICS

The LENSTAR LS 900 and the predicate devices are substantially equivalent because they use similar technology and perform similar functions to provide the ocular measurements and to perform calculations needed to allow a physician to choose the appropriate power and type of IOL for a patient eye.

{3}------------------------------------------------

# CLINICAL SUMMARY

Two prospective, non-randomized, single site comparison studies were performed to substantiate equivalence of the LENSTAR LS 900 to the stated predicate FDA approved medical devices including the IOL-Master (Carl Zeiss Meditec AG), the OLCR (Haag-Streit AG), the Accusonic A-Scan (Accutome) and Keratron (Alliance Medical Marketing). The studies were approved by an ethics committee. The studies were conducted in Berne, Switzerland.

Data includes measurements of axial length, central corneal pachymetry, anterior chamber depth, central lens thickness, average corneal radius, flat corneal axis, white-towhite distance and pupillometry.

Analysis of clinical data substantiates equivalence between the measurement data of the LENSTAR LS 900 with the all predicates.
