What is CCC in phaco?
What is CCC in phaco?
Continuous curvilinear capsulorhexis (CCC) is considered the standard and a critical step of anterior capsule opening in modern cataract surgery (either phacoemulsification or manual sutureless extracapsular cataract extraction) .
How do you make Capsulorhexis?
Summary of technique
- Anterior capsulorrhexis is stained with trypan blue.
- Use cystotome to scrape a tear in the anterior capsule.
- Remove cystotome with side turn on retraction from incision.
- Replace with capsulorrhexis microforceps and grasp one of the flaps and pull over briskly 180 degrees away from incision.
What is Hydrodissection in cataract surgery?
Hydrodissection is a technique to separate the lens nucleus from the cortex and the capsule by injecting fluid, under the anterior capsule leaflet. A fluid wave can be seen as the balance salt solution (BSS) passes between the nucleus and cortex.
Why bridle suture is done?
For two reasons : To fix the eyeball so that the eyeball doesn’t move during the procedure. To fix the eye in a downward position exposing the superior sclerocorneal junction to make the curvilinear incision and to extract the cataractous lens.
What is Sulcus IOL?
The IOL is positioned in the ciliary sulcus and the optic is captured posteriorly through the anterior and posterior capsule openings. This maintains IOL centration and prevents formation of Elschnig’s pearl and visual axis opacification posterior to the IOL.
What is capsular phimosis?
Anterior capsule fibrosis and phimosis, commonly described as anterior capsule contraction syndrome (ACCS), is the centripetal constriction and fibrosis of the capsulorhexis following cataract removal.
What is anterior Capsulorhexis?
Definition. The capsulorhexis (greek rhexis: to break) is a technique of anterior capsulotomy. The capsulorhexis delineates a circular and continuous central opening in the anterior capsule. It allows expression or phacoemulsification of the lens nucleus.
Can a cataract surgery be redone?
Cataract surgery is irreversible. This is because the cloudy natural lens that results in a cataract is removed during surgery and cannot be placed back in.
Why is hydrodissection important?
Therefore, successful hydrodissection improves our efficiency, reduces the risk of posterior capsular rupture, and by cleaving the cortical attachments, reduces the rate of posterior capsule opacification. 2,3 By optimizing our technique and instrumentation, we can reliably achieve these benefits on a consistent basis.
How do you do hydrodissection?
For this minimal fluid technique, hydrodissection was divided into four steps as follows:
- Step 1: Cleavage of the cortex from the posterior capsule.
- Step 2: Termination of injection once the hydrodissection wave has completely crossed the lens equator.
- Step 3: Use of the cannula tip to gently depress the lens.
