The laser procedure is carried out under topical anaesthetic (by instilling drops only) to numb the surface of the eye.
There is no stinging around or in the eye.
Laser treatment is TOTALLY painless.
The femtosecond laser is used to make a fine cut in the cap, and the flattening cone is brought into contact with the eye for a few seconds to ensure that it follows the shape of the cornea.
Patients may feel a sensation of suction, and for some of them this causes a slightly unpleasant transient sensation.
