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]
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 ]
Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y 3 Al 5 O 12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant , neodymium in the +3 oxidation state, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are ...
Growth of natural lens cells remaining after the natural lens was removed may be the cause, and the younger the patient, the greater the chance of this occurring. 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 ...

Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group. It is a cubic yttrium aluminium oxide phase, with other examples being YAlO 3 (YAP [2]) in a hexagonal or an orthorhombic, perovskite-like form, and the monoclinic Y 4 Al 2 O 9 (YAM [3]).
