Purpose

Occlusion of cataract substance is essential in cataract surgery, even more to reduce unwanted release of energy in the eye and enhancing fragmentation capability. An optical occlusion feedback would thus be a technical advancement to minimize unwanted energy release by the surgeon

Setting

Single Site, Ambulatory Multidisciplinary (Anterior and Posterior Segment) Surgical Center

Methods

An adjustable RGB light source built in the Nano Laser system (CETUS, A.R.C. Laser, Germany) delivers bright light through the aspiration port of the hand piece. The illumination can be set to different color shades customized to the cataract material, which can be demonstrated by surgical videos, both with a conventional and a 3d digital microscope (Munich Surgical Instruments).

Results

Occlusion is by far better visible with the additional light compared to standard microscope illumination. The light emitted through the aspiration opening of the probe is scattered maximal when occlusion is achieved and contributes to maximal material visibility. Without occlusion, the spreaded light is minimal and observation of the illumination is reduced in both microscope settings.

Conclusions

Safety during the cataract removal process can be enhanced using additional light emitted through the cataract hand piece. Illuminated cataract material directly at the aspiration tip allows the use of strong aspiration force without losing surgical control.
