Ophthalmic scalpels are precision instruments specifically designed for delicate eye surgeries, aimed at minimizing tissue damage and ensuring high precision and stability during operation.
Core Features and Classifications
* **Ultra-thin Blade:** Typically only 0.1-0.2 mm thick, some diamond blades are even thinner, minimizing trauma to sensitive tissues such as the cornea and sclera.
* **Diverse Types:** Classified according to surgical needs, including corneal blades, scleral blades, vitrectomy blades, and diamond blades, suitable for cataract, glaucoma, corneal transplantation, and vitreoretinal surgery, respectively.
* **Materials and Safety:** Blades are mostly made of stainless steel, titanium, or diamond, and are often disposable and sterile to reduce the risk of infection; the handles are ergonomically designed to ensure stability during operation.
* **Technological Evolution:** From Mechanical Blades to "Bladeless" Surgery
With technological advancements, traditional mechanical scalpels are gradually being replaced by laser technology. In femtosecond laser cataract surgery and ICL implantation, femtosecond lasers (such as the American LenSx system) have replaced traditional scalpels in completing crucial steps such as corneal incision and capsulorhexis, a technique known as "bladeless surgery." This technology is precisely controlled by a computer throughout the entire process, avoiding human error, resulting in cleaner incisions and faster postoperative recovery.
