The iris is the colored diaphragm directly visible in the eye, centered by the pupil. The removal of a fragment of the iris to the LASER is intended, by the realization of an orifice:
To prevent the occurrence of acute glaucoma or its recurrence. Also take a look here if you are looking for a plastic surgery called rhinoplasty in Las Vegas. Some people also called it a nose job or a nose surgery.
Or, more rarely, to reduce the dispersion of the iris pigment in certain forms of chronic glaucoma.
The procedure is performed on an outpatient basis. The patient sits in front of the device. The treatment is done with the interposition of a glass placed on the eye which facilitates the work of the doctor and allows to keep the eye still. The latter is insensible by the instillation of drops. Several types of LASER devices can be used (Argon LASER or LASER diode, LASER Nd: YAG) depending on the diagnosis, appearance and color of the iris. In some cases, two different LASERs are used in the same procedure. The creation of an opening in the iris is done without opening the eyeball. Moderate pain, such as pitting, burns, shocks, can be felt despite anesthesia.
In the vast majority of cases, the operated eye is painless. It may cause inflammation for a few days. It is common to observe a transient increase in intraocular pressure as well as rapidly regressive intraocular hemorrhage. The patient can return home within hours. He should be treated for a few days.
This treatment, intended to combat the possible undesirable effects, can associate an anti-inflammatory eye drops, a treatment lowering the intraocular pressure, and an eye dilatation dilating the pupil. The latter causes a visual gene predominant in near vision, and prohibits driving. It is therefore advisable, if you are active, to schedule a work stoppage during the treatment period. All medicines used also contain contraindications and undesirable side effects at the local or general level. You should read the instructions carefully and report any abnormalities to your ophthalmologist.
Your ophthalmologist will examine you in the week following the intervention on one or more occasions, and remains at your disposal to answer your questions.
Although it is perfectly standardized and usually followed very well, LASER treatment does not escape the general rule that there is no safe surgery. It is therefore not possible for your ophthalmologist to formally guarantee the success of the intervention.
Severe complications of iris laser treatment are very rare. They may require reoperation and lead, in the most extreme cases, to the loss of any vision of the operated eye, or even to the loss of the eye.
Intraocular hemorrhage is common. It generally regresses rapidly.
Persistent corneal disorder.
An increase in eye pressure which in the most severe cases may require urgent re-intervention.
Inflammation of the eye.
