Hydrodissection

Hydrodissection is a medical procedure that involves the use of fluid to separate tissues along natural planes of dissection. This technique is commonly used in cataract surgery, where it helps to separate the lens nucleus from the lens capsule.

Procedure

The procedure of hydrodissection involves the injection of a balanced salt solution between the lens capsule and the lens nucleus. This is done using a cannula, which is inserted through a small incision in the cornea. The fluid creates a plane of separation, allowing the lens nucleus to be freely rotated and subsequently removed.

Applications

While hydrodissection is most commonly associated with cataract surgery, it is also used in other surgical procedures. For example, it can be used in plastic surgery to facilitate the removal of fat during liposuction. In this context, the fluid helps to separate the fat cells from the surrounding tissue, making them easier to remove.

Risks and Complications

As with any surgical procedure, hydrodissection carries some risks. These include potential damage to the lens capsule, which can lead to a condition known as posterior capsule rupture. This can result in vision loss if not promptly treated. Other potential complications include infection and inflammation.
