Surgical knives designed for cutting the anatomical structures of the eye. These devices consist of manual, slender, handheld instruments that may have a variety of different geometric shapes and sizes. They usually include a cylindrical or flat handle attached to a very fine tapered straight or curved metallic, diamond, or silicon blade that ends in a millimetric sharp or semi-sharp cutting edge. Dedicated eye surgery knives both reusable and disposable are available for surgical and microsurgical procedures such as cornea and lens capsule cutting, cataract surgery, and eye tendon cutting (i.e., tenotomy).
