Dr Wrobel says the entrance to other countries depends on availability of excellent surgeons at excellent institutions with a strong interest in retinal implants. "We have some activities going on for other countries, but it is too early to disclose any information," he says.

What is Retinitis pigmentosa?

Retinitis pigmentosa is a genetic condition that compromises vision and often leads to blindness. Signs and symptoms usually first appear in childhood with severe vision problems that start developing in early adulthood. Photoreceptor cells in the retina are genetically programed to produce the wrong amount of proteins which hinders the retina's ability to interpret images. This leads to demise of the cells gradually thereby deteriorating vision over time.
