Smart eye drops restore vision without surgery
A research team from the Biomedical Engineering Institute in Catalonia has successfully developed a smart eye drop that restores vision without surgery, using light-based drug therapy technology (Photopharmacology). This eye drop targets conditions caused by degenerative retinal diseases such as age-related macular degeneration and retinitis pigmentosa by activating live retinal neurons with light, thereby restoring the ability to respond to light in blind animals. The results show that this technique requires only easy-to-use drops without the need for surgeries or electronic implants, and it functions under natural lighting conditions. This opens new prospects for non-surgical treatment of blindness in the future, although further clinical trials on humans are necessary before it becomes available in pharmacies.
