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 ...
Cataract surgery is generally performed by an ophthalmologist in an out-patient setting at a surgical centre or hospital. Local anaesthesia is normally used; the procedure is usually quick and causes little or no pain and minor discomfort. Recovery sufficient for most daily activities usually takes place in days, and full recovery takes about a ...
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.
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 ...
Endophthalmitis is a serious infection of the intraocular tissues, usually following intraocular surgery complications or penetrating trauma, and one of the most-severe. It is rare in cataract surgery due to the use of prophylactic antibiotics. [28] Hypopyon occurs about 80% of the time. [8] Glaucoma may occur and may be very difficult to ...
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]).
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.
