The US Food and Drug Administration (FDA) has ruled that adverts for Lasik eye surgery must tell consumers about risks.
In a letter late last week, Timothy Ulatowski, head of the Office of Compliance for the FDA's Center for Devices and Radiological Health, said that adverts for the procedure must be "truthful, properly substantiated and not misleading".
The FDA recently held a public meeting about the surgery, which found scores of people were unhappy with the result.
Many complained about double-vision, blurriness and even depression.
Lasik surgery involves cutting a flap in the eye and then using a laser to change the cornea to a shape allowing for better vision.
For people that are scared about having such an invasive procedure, there are plenty of other options.
Orthokeratology lenses are worn overnight and gently reshape the cornea while the wearer is asleep, resulting in clear
natural vision without the need for any visual aids during the day.
