Iridotomy—1064 nm Nd:YAG 111
Selecta
PBL200051, Rev J
Iridotomy—1064 nm Nd:YAG
The Selecta 1064 nm wavelength is indicated for performing an iridotomy
(hole in the iris).
Contraindications
The following represent contraindications for iridotomy. Pre-existing ocular
pathologies including:
• eyes with opacities of the media such that the iris cannot be
adequately visualized
• eyes without a pupillary block component to their glaucoma
• eyes with a glass IOL
Variations in IOL material and geometry may affect YAG procedural
parameters and clinical success. Consult the IOL implant packaging and/or
the IOL manufacturer for special considerations.
Warnings
Risks
As with any surgical procedure, there are risks in Nd:YAG laser iridotomy,
including:
• significant transient elevation of IOP
• damage to the lens
• transient bleeding from the iridotomy margin, and hyphema
• localized corneal damage
• anterior chamber reaction (including flare, cells and debris)
• closure of the iridotomy with time
• inability to control glaucoma adequately (despite a successful
iridotomy), necessitating chronic medical therapy or further
invasive intraocular surgery
• damage to the retina or choroid
In addition, there are risks that have not been reported but which are
theoretically possible in Nd:YAG laser iridotomy, including:
• persistent elevation of the IOP
• rupture of the anterior hyaloid face and anterior displacement of
the vitreous in an aphakic eye
Accordingly, the physician should make an objective assessment of the
potential benefits of Nd:YAG laser iridotomy in light of these risks.
