The summary does not mention AI, ML, or related terms, and the performance studies focus on traditional statistical comparisons of measurements.
No.
The IOLMaster is a diagnostic device that measures ocular parameters and assists in IOL power calculation. It does not directly treat or cure any condition.
No
The device is intended for biometric determination of ocular measurements and for calculations to assist in determining IOL power, which are measurements for treatment planning rather than diagnosing a disease.
No
The device description explicitly states it is a "non-contact biometry instrument" and mentions using "partial coherence interferometry and traditional ophthalmic biometry techniques," which are hardware-based measurement methods. The performance studies also compare the device to manual keratometers, which are physical instruments.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The IOLMaster is a non-contact biometry instrument that directly measures the eye using light and other techniques. It does not analyze biological samples like blood, urine, or tissue.
- The intended use and device description clearly state that the device measures ocular parameters. These are physical measurements of the eye itself, not analyses of substances from the body.
Therefore, the IOLMaster falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The IOLMaster is intended for the biometric determination of ocular measurements of axial length, anterior chamber depth, corneal radius, white-to-white (WTW), and for the measurement of pupil size and deviation of the visual axis from the center of the pupil. For patients who are candidates for intraocular lens (IOL) implantation, the device also performs calculations to assist physicians in determining the appropriate IOL power and type for implantation.
This device is intended for use by physicians and eye-care professionals and may only be used under the supervision of a physician.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A prospective, single site clinical study comparing the performance of the IOLMaster 500 with the Marco (Bausch & Lomb, Inc.) manual keratometer was conducted in 61 astigmatic eyes with at least 0.75 D of astigmatism. This study evaluated the agreement in the keratometry function for corneal power, cylindrical power (i.e., astigmatic power) and axis. The results of the study demonstrate a high level of agreement between the instruments for measurements of power in the flat and steep meridians, mean power, astigmatic power and axis. Typically, the manual keratometer measured significantly flatter radii and hence lower corneal power in both meridians. The mean power (±SD) as measured by the IOLMaster was 43.33 ± 1.37 D compared to 42.99 ± 1.39 D for the manual keratometer. Overall, the manual keratometer measured less astigmatic power (-1.38 ± 0.80 D) compared to the IOLMaster (-1.56 ± 0.86 D). The differences between the measurements would be inconsequential in toric IOL calculations.
To evaluate the repeatability and reproducibility of the IOLMaster compared to the manual keratometer, the study was conducted in two phases designed to evaluate repeatability and reproducibility of the measurements.
- In Phase 1, inter-instrument variability for both the IOLMaster and the Marco keratometer was evaluated, as was the agreement between the two instruments. Three IOLMaster units and three manual keratometer units were used, and 5 measurements were taken with each unit (30 total measurements per subject).
- In Phase 2, inter-operator variability for both the IOLMaster and the Marco keratometer was evaluated, as was the agreement between the IOLMaster and the Marco keratometer. One IOLMaster unit and one Marco manual keratometer unit were used by three operators, and 5 measurements were taken by each operator (30 total measurements per subject).
The prospective clinical study demonstrated excellent agreement between the IOLMaster and Marco manual keratometer for corneal power, astigmatic power and axis. As demonstrated by these results, for all measurements, with the exception of axis, the repeatability and reproducibility limits, and the standard deviations were smaller for the IOLMaster than for the manual keratometer. For axis, the instruments have similar repeatability and reproducibility.
Additionally, a retrospective analysis of a previously conducted prospective, single site clinical study comparing the performance of the IOLMaster 500 with the Javal (Haag-Streit) manual keratometer was conducted in 116 astigmatic eyes with at least 0.75 D of astigmatism. This study evaluated the agreement in the keratometry function for corneal power, cylindrical power (i.e., astigmatic power) and axis. In this study, five measurements were taken on each eye with one IOLMaster 500 instrument and one Javal keratometer by a single operator.

PREDICATE DEVICE
The IOLMaster 500, the subject of this 510(k), is substantially equivalent to the predicate IOL.Master 500 (Carl Zeiss Meditec, AG) cleared for marketing under 510(k) number K101182 in October 2010.
DEVICE DESCRIPTION
The IOLMaster 500 is a non-contact biometry instrument for measurements of the eve required for preoperative computation of intraocular lens (IOL) type and power. As with the IOLMaster 500 predicate device, the IOLMaster 500 provides measurements of axial length, corneal radius (keratometry), anterior chamber depth and the "white" distance (WTW).
STATEMENT OF INTENDED USE
The IOLMaster is intended for the biometric determination of ocular measurements of axial length, anterior chamber depth, corneal radius, white (WTW), and for the measurement of pupil size and deviation of the visual axis from the center of the pupil. For patients who are candidates for intraocular lens (IOL) implantation, the device also performs calculations to assist physicians in determining the appropriate IOL power and type for implantation.
This device is intended for use by physicians and eye-care professionals and may only be used under the supervision of a physician.
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS
The IOLMaster 500 has the same indications for use and operating characteristics as the predicate IOLMaster 500.
The IOLMaster 500 utilizes partial coherence interferometry and traditional ophthalmic biometry techniques to obtain measurements for axial length, corneal radius, anterior chamber depth and white-to white distance. Integrated algorithms in the software allow for the use of clinically recognized formulas for the calculation of IOL type and power prior to cataract surgery. These functions are identical for the IOLMaster 500 and the predicate device.
New software features have been added to the updated IOLMaster 500. These include implementation of the Holladay 2 IOL calculation formula, improvements in displayed parameters, and the use of Netviewer one2meet for remote connection to Carl Zeiss Meditec Service.
As the measurements are achieved in the same manner using the identical optical technology; the IOLMaster 500 is therefore substantially equivalent to the predicate IOLMaster 500 (K101182).

BRIEF SUMMARY OF PERFORMANCE TESTS AND RESULTS
A prospective, single site clinical study comparing the performance of the IOLMaster 500 with the Marco (Bausch & Lomb, Inc.) manual keratometer was conducted in 61 astigmatic eyes with at least 0.75 D of astigmatism. This study evaluated the agreement in the keratometry function for corneal power, cylindrical power (i.e., astigmatic power) and axis. The agreement between the instruments is summarized in Table 1.

- The upper limit was derived based on the method of Brand and Altman, DG. Statistical methods for assessing agreement between two methods of clinical measurement. Lancet i:307-310, 1986). The lower limit was not provided since the difference in axis is always a positive number.
The results of the study demonstrate a high level of agreement between the instruments for measurements of power in the flat and steep meridians, mean power, astigmatic power and axis. Typically, the manual keratometer measured significantly flatter radii and hence lower corneal power in both meridians. The mean power (±SD) as measured by the IOLMaster was 43.33 ± 1.37 D compared to 42.99 ± 1.39 D for the manual keratometer. Overall, the manual keratometer measured less astigmatic power (-1.38 ± 0.80 D) compared to the IOLMaster (-1.56 ± 0.86 D). The differences between the measurements would be inconsequential in toric IOL calculations.
To evaluate the repeatability and reproducibility of the IOLMaster compared to the manual keratometer, the study was conducted in two phases designed to evaluate repeatability and reproducibility of the measurements.
- . In Phase 1, inter-instrument variability for both the IOLMaster and the Marco keratometer was evaluated, as was the agreement between the two instruments. Three IOLMaster units and three manual keratometer units were used, and 5 measurements were taken with each unit (30 total measurements per subject).
- . In Phase 2, inter-operator variability for both the IOLMaster and the Marco keratometer was evaluated, as was the agreement between the IQLMaster and the Marco keratometer. One IOLMaster unit and one Marco manual keratometer unit were used by three operators, and 5 measurements were taken by each operator (30 total measurements per subject).
The results of the analysis for repeatability and reproducibility for the Marco manual Keratometer and the IOLMaster 500 are summarized in Table 2.
