YAG Laser Peripheral Iridotomy
Iridectomy
An iridectomy, also known as a surgical iridectomy or corectomy, is the surgical removal of part of the iris. These procedures are most frequently performed in the treatment of closed-angle glaucoma and iris melanoma.
Nd:YAG laser
Nd:YAG is a crystal that is used as a lasing medium for solid-state lasers. The dopant, triply ionized neodymium, Nd(III), typically replaces a small fraction of the yttrium ions in the host crystal structure of the yttrium aluminum garnet, since the two ions are of similar size. It is the neodymium i…

How successful is laser iridotomy?
Iridotomy helps to prevent AACG by flattening the convex surface of the iris and widening the angle in patients with relative pupillary block. Success rates of laser iridotomy have been reported to be from 65-76%,7,8 and are relatively low in patients of east Asian descent.
Is laser iridotomy a surgery?
Laser Iridotomy surgery, a common procedure used to help relieve eye pressure caused by glaucoma, is one of the many cutting-edge procedures we can provide. DMEI glaucoma specialist, Ben J. Harvey, MD, talks us through exactly what laser iridotomy surgery is and how it's used to treat DMEI's glaucoma patients.
Is laser iridotomy painful?
Laser Iridotomy Surgery is Nearly Painless Generally speaking, the procedure is nearly painless. Your eye is anesthetized with numbing eye drops, and a small lens is placed on the surface of the eye to help focus the laser.
What is YAG laser peripheral iridotomy?
YAG PI involves creating a tiny opening in the peripheral iris, allowing aqueous fluid to flow from behind the iris directly to the anterior chamber of the eye. This typically allows an opening up of the angle of the eye. The narrow or closed angle thus becomes an open angle.

Is laser iridotomy really necessary?
It is recommended in eyes which have the angle closed for at least half the eye and have high eye pressure or glaucoma. In eyes which have a closed angle but normal eye pressure and no optic nerve damage, laser iridotomy may be recommended as a preventive treatment.
Can you drive after iridotomy?
You should not drive for 24 hours following the treatment. You will be given short-term eye drops to use at home for a few weeks after the laser procedure.
Does laser iridotomy cure glaucoma?
Closed-angle (of pupillary-block) glaucoma is one of many types of glaucoma. Often it can be cured through a procedure called an iridotomy.
How safe is laser iridotomy?
However, laser iridotomy has low risk of side effects and is a very safe procedure that prevents a potentially devastating eye condition.
Why is my vision still blurry after YAG laser?
After YAG laser capsulotomy, it is not uncommon to experience more floaters than normal. During a YAG laser capsulotomy, the clouded capsule of the eye is broken up to allow light to pass through. Some of the increased floaters are due to small pieces of the capsule floating around in your eye.
What does YAG stand for?
YAG stands for Yttrium Aluminum Garnet. These are the crystals used to generate the laser.
Is laser iridotomy really necessary?
It is recommended in eyes which have the angle closed for at least half the eye and have high eye pressure or glaucoma. In eyes which have a closed angle but normal eye pressure and no optic nerve damage, laser iridotomy may be recommended as a preventive treatment.
Can you drive after an iridotomy?
If it is a Laser Peripheral Iridotomy (LPI) or Selective Laser Trabeculoplasty (SLT) there are no driving restrictions after the procedure.
Can you drive after LPI surgery?
When can I drive after LPI? You will need to avoid driving for 2-3 days after LPI. It is recommended that you wear sunglasses during the day for the following week after you commence driving.
Can I fly after laser iridotomy?
There is no problem in flying 24 hours after having undergone a peripheral laser irridotomy (IPL), a trabeculoplasty or any other type of surgery for glaucoma.
What is a yag PI?
YAG iridotomy, YAG PI. Laser treatment for glaucoma is used in a variety of ways. Laser can be used for angle closure, when it is applied to form a tiny opening in the iris (known as an iridotomy), or laser is used to treat the ciliary body (either externally or internally), or laser can be applied to the drainage angle ...
How big is an iridotomy?
The iridotomy is usually less than 0.75 mm in diameter.
How does SLT work for glaucoma?
SLT treatment lowers eye pressure by treating the drainage angle - the trabecular meshwork (the trabecular meshwork is a thin strip of porous tissue found in the front of the eye). This type of laser typically lowers IOP (eye pressure) by several points, and lasts for years in most cases. Like all treatments for glaucoma, the effect can wear off in time. This is important to understand, as in many chronic conditions (for example like arthritis) the treatments are aimed to prevent the situation from getting worse (in the case of glaucoma by lowering IOP to a safe level), rather than from curing the condition. Unfortunately, any field lost from glaucoma is invariably permanent, however the good news is that every point of IOP lowering makes the risk of progression of glaucoma lower. SLT also helps to reduce the fluctuations in eye pressure noted moreso in glaucoma patients.

How to do SLT?
Notes about the SLT procedure: 1 You will be asked to sign a consent form. 2 Afterwards, most patients do not notice any pain of discomfort. 3 The effect of laser treatment can take many weeks (even 2-3 months) for a drop in eye pressure to be noted. 4 If you have a dry eye, please take lubricants a little more often 2-3 days before laser, as the can be a little drier with laser treatment. 5 SLT laser works well in around 2/3rd of patients, i.e. not in everybody. SLT is a very safe treatment, safer than all types of surgery, and therefore it is considered at an earlier stage in many cases.
How long does it take to recover from YAG PI?
Recovery after YAG PI is quick, typically 2-3 days. A short course of topical steroid drops after treatment may be given to keep the eye comfortable as there can be some sensitivity to light for a few days after treatment. You will be asked to sign a consent form.

Anaesthetic drops will be put in the eye (s) that need laser. Several individual laser applications are required, and this takes only a few minutes. Each spot is perceived as a bright flash of light. Each laser application typically does not cause discomfort.
When Is Laser Iridotomy Used?
Laser iridotomy is recommended for patients whose angle is closed for at least half of the affected eye. Patients who also have risk factors for high blood pressure, diabetes, or glaucoma will also qualify for laser iridotomy.
What happens during a laser iridotomy?
During a laser iridotomy, the laser light creates a small hole in the iris, which leads to an increase in the angle between the iris and the cornea. This exposes the trabecular meshwork, encouraging fluid outflow.
What is the angle of the eye?
In laser iridotomy , the “angle” is the angle between the iris (the colored part of the eye) and the cornea, the clear window in front of the eye. The narrower the angle, the more limited the flow of fluid from the eye. This causes the fluid to back up, increasing the internal pressure on the eye.
How much does laser iridotomy cost?
The cost of the procedure ranges from $1,250 to $1,650.
Why do cataracts need surgery?
This is especially the case if cataracts develop because the inactive proteins that form on the lens of the eye could close the angle again. Cataract surgery would be required to remove the obstructions before the intraocular pressure starts building up again.
