"Decade-old adaptive optics technology can greatly improve the prescriptions used in laser in-situ keratomileusis (LASIK)—the most common laser treatment for visual disorders. [...] The data relayed by the detector dictates a prescription for the eye that has the potential to improve 20/20 to 20/10 vision, which is superhuman vision. [...] By 2010, these systems will be capable of delivering treatments that will give most patients 20/10 vision."
