In acute angle-closure glaucoma cases, surgical iridectomy has been superseded by Nd:YAG laser iridotomy, because the laser procedure is much safer. Opening the globe for a surgical iridectomy in a patient with high intraocular pressure greatly increases the risk of suprachoroidal hemorrhage , with potential for associated expulsive hemorrhage .
If narrow angle glaucoma persists after iridotomy, it is called plateau iris syndrome and subsequently managed either medically (miotics) or surgically (laser peripheral iridoplasty). This condition is sometimes discovered after an iridotomy causes a rapid increase in eye pressure. [1]
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
Surgical iridectomy can be done manually or with a Nd:YAG laser. Laser peripheral iridotomy may be done either before or following cataract surgery. [89] Swelling of the macula, the central part of the retina, results in macular oedema and can occur a few days or weeks after surgery. Most such cases can be successfully treated.

Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses.This can include various methods of surgical remodeling of the cornea (keratomileusis), lens implantation or lens replacement.
Trabeculoplasty is a laser treatment for glaucoma. It is done on an argon laser equipped slit lamp, using a Goldmann gonioscope lens mirror. Specifically, an argon laser is used to improve drainage through the eye's trabecular meshwork, from which the aqueous humour drains. This helps reduce intraocular pressure caused by open-angle glaucoma. [1]
