What are YAG lasers used for?
A YAG laser is used to puncture the anterior capsule peripheral to the IOL optic to allow the trapped material to drain. Alternatively, a posterior capsulotomy can be created to achieve the same result. Anterior capsular contraction syndrome or capsular phimosis may occur with a small capsulorhexis.
How safe is YAG laser?
YAG laser capsulotomy is a very safe procedure and complications are very, very rare. Potential pitfalls of the procedure include inadvertent damage to the patient’s lens replacement (intraocular lens) or retina, but these are very rare.
Does YAG laser hurt?
The YAG (Yttrium-Aluminum Garnet) laser uses laser light in a focused beam to make small openings in the posterior capsule to clear the clouded membrane. No anesthetic is required since the capsule has no nerve endings and therefore there is no pain, just like hair or finger nails can be cut without pain.
What was the name of the first neodymium laser?
Trivalent neodymium ion Nd 3 + was the first lanthanide from rare-earth elements used for the generation of laser radiation. The Nd:CaWO4 laser was developed in 1961 ( Johnson and Nassau, 1961 ).
Which is better Holmium laser or neodymium laser?
The holmium laser has a high absorption coefficient in water and therefore has a better safety margin and has more than 100 times the energy absorption than the neodymium laser (Maydeo et al, 2011).
When was the nd-cawo4 laser first used?
The Nd:CaWO4 laser was developed in 1961 ( Johnson and Nassau, 1961 ). Historically, it was the third laser which was put into operation (the first was ruby, the second the U 3 +:CaF laser). Over the years the neodymium laser became one of the most used lasers for application purposes.
Which is better Nd YAG or neodymium doped YLF?
Neodymium-doped YLF can provide higher pulse energies than Nd:YAG for repetition rates of a few kHz or less. Compared to Nd:YAG, the Nd:YLF crystal is very brittle and fractures easily. It is also slightly water- soluble — a YLF laser rod may very slowly dissolve in cooling water which surrounds it.
