Shimrra Jamaane's eye implants Mqaaq'its functioned as replacement eyes, and the Yuuzhan Vong employed these biological entities for this purpose. A common practice among the Yuuzhan Vong was to surgically remove their natural eyes and substitute them with mqaaq'it implants. The color of a mqaaq'it would then change to reflect the emotional state of its Yuuzhan Vong host. Maa'its, a variation utilized by Shapers, served a similar purpose but functioned as ocular microscopes. The capabilities of Mqaaq'its extended beyond the visible light spectrum, enabling them to magnify microscopic objects.
Shimrra Jamaane's eyes were replaced with mqaaq'it implants.
