During the operation, the upper part of the cornea is treated by laser, causing a change in the cornea’s convexity and refractory power. Light rays that pass through the optic system start to be focused on the retina and this improves vision.
The patient is put into a comfortable reclining position in the operating theatre, with a local anaesthetic applied using eye drops. He or she will therefore feel no unpleasant sensations.
The operation takes about 20 minutes. Immediately afterwards, the patient is given some instructions and recommendations, and is prescribed eye drops. The patient is then fit to go home.
