Precision Pulse Capsulotomy is a non laser capsulotomy procedure performed using a device with a soft collapsible tip and circular Nitinol cutting element that is connected to a control console. The Nitinol tip can be collapsed sufficiently to pass through an incision of about 2.2 mm, after which it springs back into circular shape inside the ...
The technique is most commonly used for lithotripsy of urinary calculi and the treatment of posterior capsulotomy of the lens. [3] When used in corneal surgery, picosecond and nanosecond disruptors are used on the lamellae of the corneal stroma, and the method may be preferable as it leaves the epithelium and Bowman's layer unharmed. This ...
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]).
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 appropriateness of surgery depends on a person's particular functional and visual needs and other risk factors. [52] Cataract removal can be performed at any stage and no longer requires ripening of the lens. [clarification needed] Surgery is usually outpatient and usually performed using local anesthesia. About 9 of 10 patients can achieve ...
U.S. farm industry groups want President-elect Donald Trump to spare their sector from his promise of mass deportations, which could upend a food supply chain heavily dependent on immigrants in ...
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 ...
