This procedure consists in making a perforation in the iris by using a laser to establish communication between the anterior and posterior chambers of the eye, thus preventing the route for draining the intraocular fluid becoming closed ,as this could provoke an increase in intraocular pressure.

Laser iridotomy is carried out on an outpatient basis and with topical local anesthetic (drops).
There can be minor incidents, such as discomfort during the treatment and afterwards due to the use of a contact lens used during the procedure. In some cases, patients can be troubled by excessive sensitivity to light and seeing reflections.

The risks which are most probable in relation to this type of laser treatment are :
-An increase in intraocular pressure secondary to inflammation
-Transitory blurred vision
-Intraocular hemorrhages due to a lesion of the iris vessels.
