No
Therapeutic devices are used for treating diseases or conditions. This device is described as a "diagnostic system" for "analysis of the anterior eye segment" and its stated purpose is to "take images" and "evaluate and analyze" various characteristics of the eye. It does not mention any therapeutic intervention.
Yes
The device description explicitly states, "The CM 3910 Double-Scheimpflug Camera is a non-invasive, diagnostic system designed for the analysis of the anterior eye segment..." Additionally, the intended use section lists various conditions and parameters of the eye that the device evaluates and analyzes, such as corneal shape, lens thickness, and the condition of the lens (e.g., location of cataracts), which are all aspects of diagnosis.
No
The device description explicitly states it is a "Double-Scheimpflug Camera" and describes physical components like a table-mounted system, measurement unit, control unit with CPU, blue light illumination, CCD-Camera, and a top view for eye tracking and Placido imaging. This indicates it is a hardware device with integrated software, not a software-only medical device.
Based on the provided information, the CM3910 is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- CM3910's function: The CM3910 is a device that takes images of the anterior segment of the eye. It is a non-invasive imaging system that analyzes the physical structure and characteristics of the eye.
- No sample analysis: The device does not analyze biological samples taken from the patient. It directly images and analyzes the eye itself.
Therefore, the CM3910 falls under the category of a medical imaging device rather than an In Vitro Diagnostic device.

Device Description
The CM 3910 Double-Scheimpflug Camera is a non-invasive, diagnostic system designed for the analysis of the anterior eye segment by means of Scheimpflug and Placido images. The Scheimpflug images are based on the Scheimpflug Principle for Slit Image photography. The system is table mounted and AC powered. The device consists of a measurement unit and a control unit with a CPU. The measuring system uses blue light (UV-free) given to a slit to illuminate the eye, and a CCD-Camera for taking images. The measuring unit takes pictures by a rotating scan of the anterior eye segment. It also includes a top view for eye tracking means and Placido imaging in the near infrared. From the acquired pictures, the control unit calculates a 3D-model and the topography of the eye.
All light sources used (Slit lamp, Placido Disc illumination, Top view illumination) are Light Emitting Diodes (LED) which produce little heat. Excess heat is conducted by appropriate metallic heat sinks. The encapsulation of the light sources consists of non-inflammable materials (metals, glass). The device does not contain any incandescent lamp.

Rationale for Substantial Equivalence
- . The devices have the same intended use
- The devices utilize the same measuring principles (Slit Scan and Placido Disc) .
- The devices utilize the same photographic medium (CCD Camera) .
- The CM 3910 and one predicate device use light sources of comparable wavelength and intensity . .
- The devices use the same features like a
- o Head stabilizing device
- Fixation target o
- Joy stick for measurement head adjustment o
- The devices use the same features like a
- All devices are considered "non invasive" as defined in 21 CFR §812.3(k) .
Safety
The CM 3910 is a non-invasive diagnostic system, which contacts the patient only on his/her chin and forehead. The CM 3910 does not present or pose any new or additional risks for the prescribed intended uses. The light output is of an eye safe intensity and wavelength. The electrical safety requirements for medical devices are met. The CM 3910 is proven effective for its intended uses through internal performance tests.
