Corneal molding is a technique used to treat myopia, or near- sightedness. It uses specialized contact lenses designed to reshape your cornea while you’re sleeping, changing the way light enters your eye, and subsequently, your vision. For some, corneal molding can take effect within the hour, but most patients can expect results in anywhere from 1-3 weeks.
