The description focuses on standard ultrasound measurement and IOL power calculations based on established formulas and user-entered data, with no mention of AI or ML techniques.
No.
The device is used for diagnostic measurements (axial length, corneal thickness, IOL power calculation), not for treating or mitigating a disease or condition.
Yes.
The device measures the axial length of the eye and the thickness of the cornea, and calculates IOL power for implanted IOLs, indicating its use in diagnosing and assessing eye conditions and for surgical planning.
No
The device description explicitly states it is an "ultrasound instrument" and describes hardware components like a "probe tip" that emits and receives ultrasound energy. This indicates it is a hardware device, not software-only.
Based on the provided information, the AL-2000 is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- AL-2000 Function: The AL-2000 directly interacts with the human eye using ultrasound to measure physical characteristics (axial length and corneal thickness) and perform calculations based on these measurements. It does not analyze biological specimens taken from the body.
The AL-2000 is an ophthalmic diagnostic device that uses ultrasound technology for in-vivo measurements of the eye.

Device Description
The AL-2000 is an ultrasound instrument designed for measuring the axial length of the eye and the thickness of the cornea for ophthalmic use.
Ultrasound energy is emitted from the probe tip. The probe acts as both the transmitter and receiver of ultrasound energy. Some of the energy is reflected back toward the probe in the form of an echo. Measurement data can be calculated based on both the time it takes the echo to travel back to the probe from the eye and the preset converted velocity.
The instrument provides five types of standard IOL power calculations, which can be made immediately after measuring the axial length.
The instrument uses measured (or entered) axial length and entered corneal curvature, desired postoperative refraction and lens constant values to calculate IOL power.

§ 892.1560 Ultrasonic pulsed echo imaging system.
(a)
Identification. An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Trade Name: AL-2000 Combined Biometer and Pachymeter Regulation Number: 21 CFR 892.1560 Regulation Name: Ultrasonic pulsed echo imaging system Regulatory Class: II Product Code: 90 IYO Dated: March 7, 2002 Received: March 8, 2002
Dear Ms O'Connell:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
This determination of substantial equivalence applies to the following transducers intended for use with the AL-2000 Combined Biometer and Pachymeter, as described in your premarket notification:
Transducer Model Number
Biometer 10 MHz Pachymeter 20 MHz
3
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This determination of substantial equivalence is granted on the condition that prior to shipping the first device, you submit a postclearance special report. This report should contain complete information, including acoustic output measurements based on production line devices, requested in Appendix G, (enclosed) of the Center's September 30, 1997 "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers." If the special report is incomplete or contains unacceptable values (e.g., acoustic output greater than approved levels), then the 510(k) clearance may not apply to the production units which as a result may be considered adulterated or misbranded.
The special report should reference the manufacturer's 510(k) number. It should be clearly and prominently marked "ADD-TO-FILE" and should be submitted in duplicate to:
Food and Drug Administration Center for Devices and Radiological Health Document Mail Center (HFZ-401) 9200 Corporate Boulevard Rockville, Maryland 20850
This letter will allow you to begin marketing your device as described in your premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus permits your device to proceed to market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801, please contact the Office of Compliance at (301) 594-4591. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
