Dvali Corneal Tunnel Dissector Spatula

Precision Engineering for ICRS: The Dvali Corneal Tunnel Dissector Spatula

For advanced corneal surgery, especially the treatment for keratoconus, the quality of intrastromal channels is a key factor in the effectiveness of the operation. It is the Dvali Corneal Tunnel Dissector Spatula (Left or 6.9 mm), a specialized device for ophthalmology that was designed to construct these exact pathways for the placement of the intrastromal corneal ring segment (ICRS).

Through providing a controlled process to separate corneal lamellae, this spatula guarantees a uniform tunnel width and depth, which is crucial to stabilization and the refractive outcomes for the implant.

Technical Specifications and Design

The Dvali spatula has been designed using a specific geometry designed to allow for the seamless dissection of

• Semicircular Dissector (o 6.0 millimeters): The 6mm diameter is specifically designed for diameters of rings, providing an adequate path to ensure a smooth and easy insertion, while preserving the cornea's structural integrity.
• Counterclockwise (Left) orientation: This "Left" model is designed specifically to work with clockwise and counterclockwise movement. Surgeons frequently utilize this with a "Right" model to ensure an aesthetically balanced tunnel formation starting from the initial incision.
• Ergonomic round handle. The 5mm diameter handle, it provides an ergonomic grip. This allows for micro-rotational motions required to slide the dissector along the stroma with minimal force.
• Minimal Dimensions: Its overall size is 95 millimeters (3.75"), which gives the surgeon great maneuverability under the microscope for surgery.

Material Excellence: Titanium and Stainless Steel

Available in high-quality Titanium as well as Stainless Steel The Dvali dissector was designed for the challenging working environment of the operating room.

1. Titanium Benefits: Often preferred for its lightweight properties (approx. 40 percent less than steel) It helps reduce hand fatigue when performing delicate movements. It's also non-magnetic and extremely resists corrosion, which means the equipment is "like new" after hundreds of years.
2. Stainless Steel Durability: For those who want an older-fashioned "weight" and tactile feel, the surgical-grade stainless steel model offers outstanding Tensile strength as well as polished edges for a smooth tissue entry.

Clinical Applications in Modern Keratoconus Surgery

The main purpose of the Dvali spatula lies in the placement of segments such as Ferrara rings and Kerarings (Mediphacos) and KERATACx. In the procedure, the blade that is semicircular is inserted into a pocket. Due to its blunt but thin design, it serves as a "corneal separator," splitting the stromal fibers on the natural plane, rather than cutting them. This helps reduce trauma and facilitates quicker healing post-operatively.

Maintenance and Reusability

The Dvali Corneal Tunnel Dissector Spatula is an reuseable, not sterile device. It should be cleaned thoroughly and sterilized after every use. The sturdy construction of this instrument guarantees it can withstand sterilization at high temperatures without losing its precise curvature or tip strength.
