What is Hydrodelineation in cataract surgery?

What is Hydrodelineation in cataract surgery?

Hydrodelineation is the act of separating an outer shell (or multiple shells) of the lens of the eye from the central compact mass of inner nuclear material (also called endonucleus) during a cataract surgery by the forceful irrigation of a fluid into the mass of the nucleus.

How are polar cataracts treated?

Treatment: When posterior polar cataracts become visually significant (either in infancy if the cataracts are large enough to be amblyogenic, or in adulthood when they cause glare), they can be surgically removed. However, the high risk of posterior capsular rupture makes surgical removal often very difficult.

How do you do Hydrodissection?

For this minimal fluid technique, hydrodissection was divided into four steps as follows:

1. Step 1: Cleavage of the cortex from the posterior capsule.
2. Step 2: Termination of injection once the hydrodissection wave has completely crossed the lens equator.
3. Step 3: Use of the cannula tip to gently depress the lens.

What is meant by Hydrodissection?

Hydrodissection is the process of injecting small amounts of a special fluid into the capsule of the lens in the eye in order to make dissection easier. It makes the surgeon more capable of performing maneuvers during extracapsular or phacoemulsification surgeries.

What is meant by phacoemulsification?

Phacoemulsification: A type of cataract surgery in which the lens with the cataract is broken up by ultrasound, irrigated, and suctioned out.

What is done in phacoemulsification?

Phacoemulsification, or phaco. A small incision is made on the side of the cornea, the clear, dome-shaped surface that covers the front of the eye. Your doctor inserts a tiny probe into the eye. This device emits ultrasound waves that soften and break up the lens so that it can be removed by suction.

What is the recovery time for cataract surgery?

The recovery time for cataract surgery is short. Any soreness and discomfort should disappear within a couple of days. However, depending on the nature and size of your cataracts, and your physiology and ability and heal, full recovery could take anything from four weeks to six weeks.

What causes polar cataract?

It has been suggested that posterior polar cataracts are caused by persistence of the hyaloid artery6,7 or invasion of the lens by mesoblastic tissue. 8,9 It appears that posterior polar cataract forms during embryonic life or early in infancy and usually becomes symptomatic 30–50 years later.
