capsulorhexis

(kăp″sū-lor-ĕk′sĭs)
A common method of cataract extraction in which a circular incision is made in the anterior capsule to permit lens extraction.

capsulorhexis 

A form of capsulotomy in which the incision of the anterior capsule is made in a smooth circular pattern along the periphery of the lens to enable removal of opaque lens material during extracapsular cataract extraction. It is the preferred method of capsulotomy when inserting a rigid intraocular lens because the incision is less likely to tear than that made by the 'can-opener' technique.

Anterior chamber was filled by sodium hyaluronate (3.0%), and a 4.0-5.0 mm anterior continuous curvilinear capsulorhexis was performed by using a capsulorhexis forceps.
Long-term results of phacoemul-sification combined with primary posterior curvilinear capsulorhexis in adults.
However, this device only has a capsulorhexis stage and not the other modules available in the Eyesi[R] simulator.
A major incision of 2.4 mm in size was made in the cataract surgery, and for stabilization of the anterior chamber and endothelial protection, 3% sodium hyaluronate, 4% chondroitin sulfate (Viscoat), and 1% sodium hyaluronate (Provisc) were used during capsulorhexis and intraocular lens (IOL) implantation.
It is generally advised that primary posterior capsulorhexis (PPC) should be performed in children younger than 4 years of life, since the risk of developing PCO even if posterior capsule remains intact is 100%, due to more reactive inflammatory response in younger age [20, 39, 40].
Cataract surgery requires sufficient mydriasis, to facilitate capsulorhexis or capsulotomy, phacoemulsification, and finally intraocular lens insertion.
The procedure involves a small self-sealing incision on the cornea, followed by an opening created on the anterior capsule of the lens known as a capsulorhexis. The inner lens is then broken up using a phacoemulsification procedure and aspirated out.
Among the areas they consider are managing capsulorhexis and complications, soft and mature cataract management and complications, intraocular lens implantation in the absence of adequate capsular support, machine management in complicated cases, toxic anterior segment syndrome and endophthalmitis, and prevention pearls and damage control.
TB is employed in the course of cataract surgery to visualize the anterior capsule during capsulorhexis [17,18].
After sterile preparation, a 2,2 mm clear corneal incision, intracameral lidocaine, intracameral hydroxypropyl methylcellulose (Acryvisc[R], Zeiss, Oberkochen, Deutschland), and 55.5 mm continuous curvilinear capsulorhexis were followed by phacoemulsification performed at the same phacomachine (Millenium[R], Bausch & Lomb Storz) in all patients, aspiration irrigation, and hydrophobic IOL implantation.
The phacoemulsification was performed from 2.4 mm scleral tunnel and then the lens capsule was grasped and removed by 23-gauge capsulorhexis forceps from the corneal side port.
After clear cornea incision (knife 2.4 mm) and paracentesis, continuous curvilinear capsulorhexis was performed using forceps.
