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.

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.

However, contraction of the capsulorhexis orifice as a result of fibrosis may cause IOL dislocation and associated refractive changes.
The technique of continuous curvilinear capsulorhexis (CCC) allows placement of IOL in the natural anatomical position.
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.
In most eyes, ECCE was performed using the W-shaped incision [Figure 1],[sup][8] followed by a continuous curvilinear capsulorhexis (CCC).
The routine surgical procedure for congenital cataract is to perform continuous curvilinear capsulorhexis (CCC), aspirate the soft lens matter, perform posterior circular capsulorhexis and remove the anterior vitreous.
20,21] Recently, it has also been shown that phacoemulsification with continuous curvilinear capsulorhexis (CCC) induced a less severe blood-aqueous barrier breakdown than extra capsular cataract extraction (ECCE) with a linear capsulotomy.
A continuous curvilinear capsulorhexis was performed and all of the eyes received intracameral injections of two viscoelastic substances (Viscoat--Alcon labs, SP, Brazil; Metilcelulose 2%--Ophthalmos, SP, Brazil) to maintain the chamber and protect the endothelium.
Anterior capsulorhexis was performed using a pair of capsulorhexis forceps or a bent 27-gauge needle (Figure 1(c)).
But the smaller diameter of the capsulorhexis meant that Kathy didn't get a 6-mm clear aperture when she chose a 6-mm lens; the aperture was closer to 5 mm.
