The description focuses on image acquisition and storage, with no mention of AI/ML for image analysis or interpretation.
No
The device is described as an imaging and observation system used for diagnosis and management, not for treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is for "diagnosis and management of anterior segment diseases."
No
The device description explicitly lists hardware components including a laser scanning camera, optics, mount, power supply, and a personal computer, indicating it is a hardware-based system with associated software.
Based on the provided information, this device 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.
- Device Function: This device is an imaging system that directly examines the cellular layers of the anterior segment of the human eye in vivo (within the living body). It uses confocal microscopy to acquire images of the eye's structure.
- Lack of Sample Analysis: The device does not analyze a sample taken from the body. It is a diagnostic imaging tool that interacts directly with the patient's eye.
Therefore, while it is a diagnostic device used for the diagnosis and management of anterior segment diseases, it falls under the category of in vivo diagnostic imaging rather than in vitro diagnostics.

Intended Use / Indications for Use
The intended use of the Heidelberg Retina Tomograph II / Rostock Cornea Module is to provide three-dimensional images and observation of the cellular layers of the anterior segment.
Imaging and observation of the cellular layers of the anterior segment of the human eye, for the diagnosis and management of anterior segment diseases.

Device Description
The system consists of the HRT II laser scanning camera, the Rostock Cornea Module optics, a mount with headrest, a power supply, and a personal computer. For an examination, the Rostock Cornea Module optics is placed on the laser scanning camera, positioned in front of the patient's eye, in contact with the cornea. The contact surface is a sterile PMMA plate. Images of the anterior segment are acquired, displayed on the computer monitor and stored on the hard drive of the computer from where the images can be retrieved at a later time.
The system generates images by scanning the cornea of the eye under examination and detecting the light reflected or backscattered from the cornea. The light detection system has a confocal optical arrangement, so that a two-dimensional image acquired within its focal plane can be considered as an optical section through the corneal layer located at the current focal plane. In addition, by moving the focal plane step by step, a sequence of section images at different locations of the focal plane can be acquired. This sequence of images provides a layer-by-layer three-dimensional image. The acquired images are displayed on the computer monitor and stored on the computer's hard disk for later use.
