Ophthalmology is the medical speciality devoted to the diagnosis and treatment of all conditions affecting the eyeball, tear ducts and eyelids. Outpatient consultations and treatment account for most of the activity involving this speciality. It is possible to provide numerous forms of treatment during outpatient consultations, such as laser treatment of the retina or of a glaucoma.

In the Canton of Haut-Valais, patients are treated by experienced ophthalmologists who carry out operations at Brig Hospital. In emergency cases, patients with a condition affecting their eyes can go to the Accident and Emergency departments in Visp and in Brig.
