In acute angle-closure glaucoma cases, surgical iridectomy has been superseded by Nd:YAG laser iridotomy, because the laser procedure is much safer.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 .
A laser peripheral iridotomy (LPI) is the application of a laser beam to selectively burn a hole through the iris near its base. LPI may be performed with either an argon laser or Nd:YAG laser. [6] [7] There is currently no sufficient evidence to show any benefit on the use of iridotomy versus no iridotomy to slow down visual field loss.
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]
Surgical iridectomy can be done manually or with a Nd:YAG laser. Laser peripheral iridotomy may be done either before or following cataract surgery. [87] 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.
Laser eye surgery or laser corneal surgery is a medical procedure that uses a laser to reshape the surface of the eye to correct myopia (short-sightedness), hypermetropia (long-sightedness), and astigmatism (uneven curvature of the eye's surface). Importantly, refractive surgery is not compatible with everyone, and people may find on occasion ...

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.
