YAG LASERS IN CATARACT SURGERY
International Ophthalmology Clinics, 1987Le laser YAG est largement utilise pour pratiquer des capsulotomies posterieures et peut etre un instrument majeur dans le traitement de complications postoperatoires telles qu'un blocage pupillaire un glaucome malin une incarceration du vitre dans la plaie operatoire et pour lyser des ...

The YAG laser: An American experience
American Intra-Ocular Implant Society Journal, 1983We used the OPL3 neodymium-YAG laser to treat 86 patients, 41 male and 45 female, for secondary opacification of an intact posterior capsule one month to four years after planned extracapsular cataract extraction or phacoemulsification, with or without intraocular lens implantation.

Experimental YAG Laser Sclerostomy
Archives of Ophthalmology, 1984A Q-switched neodymium-YAG laser was used to produce a corneoscleral perforation in human cadaver eyes. A through-and-through incision could be created solely with the YAG-laser at peak pulse energies of 16 millijoules (mJ). The minimal total energy required for perforation was 3,312 mJ. However, "optimal" perforation, producing splitting along natural

Ultrafast Phenomena, 1994
Recent advances in mode-locked solid-state lasers have resulted in pulses as short as 8.5 fs in the 800 nm region from Ti:sapphire oscillators [1]. Using similar techniques, sub-50 fs pulses [2-4] have been generated in another solid-state laser system, Cr:forsterite, which operates in the 1.2 to 1.3 μm range.

Erbium‐YAG and holmium‐YAG laser ablation of the lens
Lasers in Surgery and Medicine, 1994AbstractEr‐YAG (2.9 μm, 200 JJLS pulsewidth) and Ho‐YAG (2.12 μm, 250 μS pulsewidth) lasers were used to irradiate bovine crystalline lenses. Mass ablated increased with increasing fluence for both lasers and was greater for the Er‐YAG than the Ho‐YAG laser at all fluences. The mass loss vs. fluence curve was nonlinear for the Er‐YAG and linear for the

Ocular Effect of Neodymium-Yag Laser
American Journal of Ophthalmology, 1984We aimed a high-powered pulsed neodymium-YAG laser incrementally from air to the anterior portion of the vitreous in rabbits to evaluate its effect on the corneal endothelium, the lens, and the dynamics of intraocular fluid. Corneal endothelium damage occurred as much as 3.5 mm away from the site of optical breakdown.

Safety of Neodymium-Yag Lasers
American Journal of Ophthalmology, 1983The neodymium-YAG (yttrium, aluminum, garnet) laser is fundamentally different from the commercially available argon, ruby, carbon dioxide, and krypton lasers. All of those lasers work by the generation of heat because the energy of the laser is absorbed in the form of heat in a tissue. This produces a thermal coagulation of tissue in a focal area. The
