During PRK, the specialist utilizes topical anesthesia to numb the eyes before placing a speculum over them to stop blinking. The outer layer of epithelial cells is eliminated either mechanically (utilizing an unique brush or sweeping tool), with an alcohol option, or by computer-controlled laser pulses.
