180 Degrees
180 degrees of Selective Laser Trabeculoplasty using Neodymium:Yttrium Aluminum Garnet (YAG) laser Selective Laser Trabeculoplasty: The procedure uses light energy provided by a neodymium (Nd):Yttrium Aluminum Garnet (YAG) laser that is directed into the iridocorneal angle via a goniolens viewed through a standard slit lamp. Neodymium:Yttrium Aluminum Garnet (YAG) laser: The procedure uses a 400 μm spot size of light energy provided by a low-energy, Q-switched, frequency-doubled (532 nm) neodymium (Nd):Yttrium Aluminum Garnet (YAG) laser with a short pulse duration of 3 nanoseconds that is directed into the iridocorneal angle via a goniolens viewed through a standard slit lamp.
