Pupillary distortion may be encountered if the iris root or peripheral iris has been treated.
This distortion may or may not be permanent, depending on the severity of the accidental
damage.
WARNING
Intraocular pressure elevations have been reported to occur in up to 53% of eyes when
360º of the trabecular meshwork has been treated with 100 spots at the initial session.
Intraocular pressure rises occur most frequently from 1 to 2 hours following laser
treatment, although they may occur several hours afterward. For this reason, it is
imperative to monitor patient intraocular pressure after laser treatment for up to 24 hours.
Peripheral anterior synechiae may occur when the posterior portion of the trabecular
meshwork or other structures posterior to the meshwork are treated. These are best
avoided by meticulous delivery of a well-focused laser beam.
Transient corneal epithelial burns have reportedly been resolved within 1 week without
scarring. Endothelial burns are rarely encountered when careful focusing is employed.
Rarely, severe iritis may occur, related to either an unusual patient response or improper
spot location.
