Posterior Capsulotomy—1064 nm Nd:YAG
The Selecta 1064 nm laser is indicated for disruption of the posterior capsule
of the eye (posterior capsulotomy).
Contraindications
The following represent contraindications for posterior capsulotomy or
pupillary membranectomy:
• pre-existing ocular pathologies including:
– corneal edema that interferes with visualization of the capsule
– diffuse haze of the aqueous humor
– extensive corneal dystrophy
• chronically elevated intraocular pressure (IOP), especially when
uncontrollable under medication
• eyes with no potential visual function
• subjects with glass posterior chamber intraocular lenses (IOL),
except those subjects whose medical condition precludes invasive
surgery
• 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 involved in Nd:YAG laser
posterior capsulotomy or pupillary membranectomy, including:
• significant transient elevation of intraocular pressure (IOP),
• persistent elevation of IOP,
• cystoid macular edema,
• rupture of the anterior hyaloid face and anterior displacement of
the vitreous,
• retinal detachment
The potential impact of using of high energy levels and a high number of laser
pulses (i.e., at the upper limits of the available ranges) to disrupt some
pupillary membranes must be considered. The anterior shift of the plane of
optical breakdown from the focal point and elongation of the breakdown
region that occurs as power increases become significant at high energy levels.
These effects may result in increased risk of injury to the corneal endothelium,
the iris, and, if present, an intraocular lens (IOL). Corneal. iris, and IOL
