Light-emitting diode technology eliminates the need for an external light source for vitreoretinal illumination and provides good visibility, according to a study.

"The first intrasurgical use of this LED-based intraocular illumination system demonstrated well-illuminated structures with clearly recognizable retinal details," the authors said.

The study evaluated a prototype for ocuLED (Geuder), an illumination system with a built-in LED in the handle.

The externally powered system works with a cool white or neutral white LED. Although the ocuLED handle is slightly larger than those of typical light fibers, the size does not affect intrasurgical handling, the study found.

The maximum wavelength spectrum was 565 nm, with a second peak at 455 nm, and the proportion of blue light was low compared with xenon and mercury vapor light sources. In addition, maximum radiant power and irradiance did not cause phototoxic damage, according to the study.

Sterile single-use ocuLED will be available in 20-, 23- and 25-gauge sizes.
