Healon: The Essential Viscoelastic Substance for Ophthalmic Surgeries

Healon is a type of viscoelastic substance used in ophthalmic surgeries

Healon is a type of viscoelastic substance used in ophthalmic surgeries. It is a sterile, non-pyrogenic solution that is commonly used during cataract surgeries and other intraocular procedures.

The primary function of Healon is to maintain the stability and integrity of the eye during surgery. It acts as a cushioning agent and provides protection to the delicate structures within the eye. Additionally, Healon helps to create and maintain space in the eye, allowing the surgeon to perform the procedure with precision.

Healon is composed of sodium hyaluronate, which is a naturally occurring substance found in the body, particularly in the tissues and fluids of the eye. This material is highly biocompatible and does not elicit an immunological response.

During cataract surgery, the natural lens of the eye is replaced with an artificial intraocular lens (IOL). Healon is used to create and maintain a stable environment for lens insertion and positioning. It also helps to prevent damage to the corneal endothelium, which is the innermost layer of cells in the cornea.

Healon is typically injected into the anterior chamber of the eye through a small incision. It forms a protective coating on the cornea and other intraocular structures, allowing the surgeon to manipulate and remove the cataractous lens without causing damage.

After the surgery, the Healon is gradually absorbed by the body and replaced by the natural fluids of the eye. It is well-tolerated by most patients and does not usually cause any adverse reactions or complications.

In summary, Healon is a viscoelastic substance used in ophthalmic surgeries to maintain the stability of the eye during procedures like cataract surgery. It helps create space in the eye, protects delicate structures, and aids in the insertion and positioning of an artificial intraocular lens.
