Months or years after the cataract operation, the remaining posterior lens capsule can become opaque and vision will be reduced in about 20–25% of eyes. [4] This is known as posterior capsule opacification (PCO). PCO is best treated by posterior capsulotomy using YAG laser. [4]
Slit lamp photograph of posterior capsular opacification visible a few months after implantation of intraocular lens in eye, seen on retroillumination. Nd:YAG lasers are used in ophthalmology to correct posterior capsular opacification, [6] after cataract surgery, for peripheral iridotomy in patients with chronic [7] and acute angle-closure glaucoma, [8] where it has largely superseded ...
The technique is most commonly used for lithotripsy of urinary calculi and the treatment of posterior capsulotomy of the lens. [3] When used in corneal surgery, picosecond and nanosecond disruptors are used on the lamellae of the corneal stroma, and the method may be preferable as it leaves the epithelium and Bowman's layer unharmed. This ...
A posterior capsulotomy is an opening of the back portion of the lens capsule, which is not usually necessary or desirable unless it has opacified. [12] The types of capsular openings commonly used in MSICS are the continuous curvilinear capsulorhexis, the can-opener capsulotomy, and the envelope capsulotomy. [4]
In the early 1980s, Danièle Aron-Rosa and colleagues introduced the neodymium-doped yttrium aluminum garnet laser (Nd:YAG laser) for posterior capsulotomy. [7] In 1985, Thomas Mazzocco developed and implanted the first foldable IOL, and Graham Barrett and associates pioneered the use of silicone, acrylic, and hydrogel foldable lenses. [7]
Management involves cutting a small, circular area in the posterior capsule with targeted beams of energy from a laser, called Nd:YAG laser capsulotomy, after the type of laser used. The laser can be aimed very accurately, and the small part of the capsule which is cut falls harmlessly to the bottom of the inside of the eye.
Accommodative intraocular lenses may also have a slightly higher risk of developing posterior capsule opacification (PCO), though there is some uncertainty around this finding. [16] PCO is a common side-effect of many cataract surgeries and is easily treatable with a one-time laser capsulotomy procedure (see below).
Yttrium aluminium garnet laser (YAG laser) to correct posterior capsular opacification (specially after removal of a cataract, if required), peripheral iridotomy, retinal surgery, laser-assisted sub-epithelial keratectomy [4] etc. Electrolysis: used for permanent hair removal Electrocautery: for electrosurgery Phacoemulsification
