Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this clinical trial is to evaluate the safety of the SPECTRALIS CENTAURUS device (HuCE-optoLab, BFH TI, Biel, CH) in a clinical setting on patients with retinal diseases.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Optical microsurgery of the retinal pigment epithelium (RPE) requires reliable real-time dosimetry to prevent unwanted overexposure of the neuroretina. The SPECTRALIS CENTAURUS device implements optical coherence tomography (OCT) to detect intentional elimination of RPE cells caused by a prototype laser for selective retina therapy (SRT).

Within this clinical trial the safety of the SPECTRALIS CENTAURUS device and its ability to detect RPE cell damage towards selective real-time laser microsurgery will be evaluated.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Treatment with the SPECTRALIS CENTAURUS device

In Stage 1, two laser pattern will be applied in areas of the retina that require ablative laser photocoagulation.

In Stage 2, a laser pattern will be applied along and on the outside of the arcades. Furthermore, a treatment pattern will be applied to an area temporal to the fovea affected by intermediary age-related macular degeneration (AMD) and confluent soft drusen.
