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 ...
Swelling of the macula, the central part of the retina, results in macular oedema and can occur a few days or weeks after surgery. Most such cases can be successfully treated. [ 31 ] Uveitis–glaucoma–hyphema syndrome is a complication caused by the mechanical irritation of a mis-positioned IOL over the iris, ciliary body or iridocorneal angle.
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 ...
PCO is a common side-effect of many cataract surgeries and is easily treatable with a one-time laser capsulotomy procedure (see below). Accommodating IOLs interact with ciliary muscles and zonules , using hinges at both ends to "latch on" and move forward and backward inside the eye using the same nerves and musculature as normal accommodation.
Manual small incision cataract surgery (MSICS), which is considerably more economical in time, capital equipment, and consumables, and provides comparable results, is popular in the developing world. [6] Both procedures have a low risk of serious complications, [7] [8] and are the definitive treatment for vision impairment due to lens ...
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 ...
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.
