Ophthalmic surgery being performed using OVD.

An Ophthalmic Viscosurgical Device (OVD) is a specialized medical device used in ophthalmic surgery to maintain the shape and protect the delicate structures within the eye. This article provides an overview of OVDs, their uses, and their importance in various eye surgeries.

Purpose

Ophthalmic Viscosurgical Devices serve several critical purposes during eye surgeries:

• Maintaining Space: OVDs are used to create and maintain space within the eye during surgery. This space allows the surgeon to work effectively and prevents the collapse of the anterior chamber.

• Protection: OVDs provide a protective barrier to delicate eye structures, such as the corneal endothelium, preventing damage during surgical maneuvers.

• Optical Clarity: They help maintain optical clarity within the eye, ensuring that the surgeon has a clear view of the surgical site.

Types of OVDs

There are different types of OVDs, each with specific properties and uses. Common types include:

• Sodium Hyaluronate: A clear, viscous substance used in cataract surgery and other anterior segment procedures.

• Chondroitin Sulfate: Used for its viscoelastic properties and biocompatibility, often in glaucoma surgery.

• Hydroxypropyl Methylcellulose: A clear gel used in anterior segment surgeries and for protecting the corneal endothelium.

• Sodium Chondroitin Sulfate-Sodium Hyaluronate: A combination of two substances, providing both protection and space maintenance.

Surgical Applications

Ophthalmic Viscosurgical Devices are commonly used in various eye surgeries, including:

• Cataract Surgery: OVDs are essential for maintaining space and protecting the delicate lens capsule during cataract removal and IOL (intraocular lens) implantation.

• Glaucoma Surgery: OVDs help create space and protect the corneal endothelium during procedures like trabeculectomy.

• Corneal Transplant Surgery: OVDs are used to maintain space and protect the donor cornea during transplantation.

• Vitreoretinal Surgery: In some vitreoretinal surgeries, OVDs may be used to stabilize the retina and maintain space within the vitreous cavity.

Advancements and Research

Advancements in ophthalmic surgery continue to drive research into OVDs, with a focus on improving their safety, effectiveness, and biocompatibility. Ongoing studies explore new formulations and applications in eye surgery.
