The description focuses on standard ultrasound technology and software modifications for PC interfacing, with no mention of AI or ML algorithms for data processing or interpretation.
No.
The device is used for measurement and calculation, not for treatment or therapy. It aids in surgical planning but does not provide a therapeutic effect itself.
Yes
The device measures physical parameters of the eye (axial length, anterior chamber depth, lens thickness) and calculates the optical power of the IOL. While these measurements are used for planning surgery, they are quantitative assessments of the eye's physical state rather than providing a diagnosis of a disease or condition itself.
No
The device description explicitly states it utilizes an eye-contact probe to generate and receive ultrasound pulses and includes a control unit which is an interface between the probe and a personal computer. These are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The Accutome A-Scan Plus Connect device uses ultrasound to directly measure structures within the eye (axial length, anterior chamber depth, lens thickness). It does not analyze samples taken from the body.
- Intended Use: The intended use is to measure ocular structures and calculate IOL power for cataract surgery planning. This is a direct measurement and calculation based on the physical properties of the eye, not an analysis of a biological sample.
Therefore, the device falls under the category of a medical device used for direct measurement and calculation within the body, not an in vitro diagnostic device.

Device Description
The Accutome A-Scan Plus Connect device is designed as a biometer, which uses pulsed echo ultrasound to measure the axial length, and the location of other structures of the eye. It utilizes an eye-contact probe to generate and receive the ultrasound pulses, and provides a one-dimensional display of returning pulse echoes, with positive peaks to indicate the location of ocular structures. The distance between peaks can be measured.
The new A-Scan Plus Connect model uses the personal computer as the main computing vehicle and display instead of the dedicated computer/display of the predicate device. The software modifications in the Connect model are those necessary to interface the processing, data storage, display, and printing capabilities of the personal computer.
The A-Scan Plus connect control unit is an interface between the ultrasonic probe and a personal computer. It consists of a microprocessor based printed circuit board, with USB connections, enclosed in a plastic case.
The energy source for the A-Scan Plus Connect is USB power from the personal computer instead of the AC to DC adapter used to power the predicate device.
The chemical composition of patient contact materials is identical to that of the predicate device.

Summary of Performance Studies
Physical Accuracy Test
This test compares the distance measured ultrasonically by the A-Scan Plus Connect and the physical distance measured by a mechanical dial indicator. The test results for both the A-Scan Plus Connect model and the predicate device were well within the 0.1mm acceptance criteria.
Data Comparison Test: Accusonic A-Scan (predicate) vs. A-Scan Plus Connect
The objective of this test is to compare critical parameter results between the two devices under conditions of the same input test fixture and values.
Results: All of the data met the established acceptance criteria:
-Ultrasound measurements for all eye types shall be within 0.05mm
-IOL calculation results for all formulas shall be within one decimal place
Internal Validation Tests
A test plan was developed to evaluate proper operation and usability for all device modes/options. The plan consisted of 83(as of 12/5/12) specific evaluations of characteristics of the device, most of which required multiple actions or observations on the part of the user.
Results: All operations and features were fully functional. There were no errors or deficiencies in the patient information. The usability was judged to be superior to the predicate device.
External Validation Tests
A checklist was developed which requests quantified critique regarding the safety, functionality and usability of the device via 11 specific questions. A Rating Scale from 1 to 5 was used with:
5 = best, very user friendly, no problems; and 1 = not acceptable, very unfriendly, significant problem that must be corrected.
Results: The device was evaluated on 29 different patients at 3 different locations by 3 different experienced technicians/ophthalmologists. One of the users had detailed experience with the predicate device and two with a competitive biometer.
Safety was ranked 5 by every user. The average rating for the 9 specific attributes enumerated was 4.8. The "Overall Rating" of the device was 5 by all users. There were no ratings of 1 or 2 in any of the tests.
