This is one of the most important concerns that patients have. No patient in our practice has ever lost their vision, or suffered any untoward accident or misadventure leading to blindness (or even serious vision compromise) as a result of laser treatment. No patient in any of the extensive FDA studies of excimer laser treatment has suffered profound vision loss. In the entire world experience, we are aware of an extremely small number of cases (approximately one per million surgeries performed) that have caused serious eye or vision problems. That includes surgeries done by untrained or ill-trained surgeons, experimental and “off-brand” lasers, and so forth. It is the general consensus among very experienced, competent US and European surgeons that this should not happen in the hands of good surgeons doing good work with proper equipment.
