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 ...
The risk of retinal detachment is the greatest in the first 6 weeks following a vitreous detachment, but can occur over 3 months after the event.. The risk of retinal tears and detachment associated with vitreous detachment is higher in patients with myopic retinal degeneration, lattice degeneration, and a familial or personal history of previous retinal tears/detachment.
Danièle Aron-Rosa (born 1934) is a French-Tunisian ophthalmologist and physician-scientist most known for developing the picosecond, ophthalmic Nd:YAG laser for eye surgeries. She has been called one of the two most respected laser pioneers in ophthalmology, alongside Franz Fankhauser .
removing all the contents of the eyeball during evisceration (complete removal of all structures within the eye in diseases like endophthalmitis: Lid plate: flat large instrument that has a groove and is placed between the lid and globe of the eye to provide a solid support for eyelid surgery Hammer, chisel and bone gouge: bone cutting and shaping
When performed with a YAG laser designed specifically for vitreolysis, reported side effects and complications associated with vitreolysis are rare. However, YAG lasers have traditionally been designed for use in the anterior portion of the eye, i.e. posterior capsulotomy and iridotomy treatments. As a result, they often provide a limited view ...
An eye examination, commonly known as an eye test, [1] is a series of tests performed to assess vision and ability to focus on and discern objects. [2] It also includes other tests and examinations of the eyes. [2] Eye examinations are primarily performed by an optometrist, ophthalmologist, or an orthoptist.
Er:YAG lasers can be used in laser aided cataract surgery but owing to its water absorbable nature Nd:YAG is preferred more. [8] Erbium YAG dental lasers are effective for removing tooth decay atraumatically, [9] often without the need for local anesthetic to numb the tooth. Eliminating the vibration of the dental drill removes the risk of ...
Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses.This can include various methods of surgical remodeling of the cornea (keratomileusis), lens implantation or lens replacement.
