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 ...
Capsulorhexis or capsulorrhexis, and the commonly used technique known as continuous curvilinear capsulorhexis (CCC), is a surgical technique used to remove the central anterior part of the capsule of the lens [1] from the eye during cataract surgery by shear and tensile forces.
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 ...
Depending on the procedure, they should avoid driving for at least 24 hours after the surgery, largely due to effects from the anaesthesia, possible swelling affecting focus, and pupil dilation causing excessive glare. At the first post-operative check, the surgeon will usually assess whether the patient's vision is suitable for driving. [94]
At the first post-operative check, the surgeon will usually assess whether vision is suitable for driving. [38] With small-incision self-sealing wounds used with phacoemulsification, some of the post-operative restrictions common with intracapsular and extracapsular procedures are not relevant.
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 ...
A peripheral iridectomy is the surgical removal of a portion of the iris in the region of its root, leaving the pupillary margin and sphincter pupillae muscle intact. [2] It is used in the treatment of glaucoma. [1] A preliminary iridectomy, or preparatory iridectomy, is the surgical removal of part of the iris preceding cataract extraction. [2]
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 ...
