LASIK stands for Laser in situ keratomilieusis. It is a form of laser surgery that is used to correct vision. It must be performed by an ophthalmoligist. If successful it can remove the need of the patient to use glasses or contact lenses. It is preferred over the alternative, PRK, as it causes less pain and requires less time to recover.

Complications from LASIK are quite rare, but they do occur. They can include,

· Dry eyes
· Over or under correction
· Light sensitivity
· Double vision
· Slipped corneal flap

LASIK surgery is improving rapidly as the technology becomes better. However, there are presently no major studies on the occurrence and risk of long-term complications and patients should be aware of this before opting for the procedure. The procedure is now being more fully monitored and controlled by health services to ensure quality and safety are not compromised.
