Abstract
Embodiments of the present disclosure generally relate to microsurgical cutting devices for ophthalmic procedures. In certain embodiments, a cutting tool assembly includes a first blade in a fixed position and a second blade configured to move relative to the first blade to perform a cutting motion. The first blade includes a first longitudinal body portion and a first end portion extending laterally from the first body portion. A distal surface of the first end portion has a bowed morphology to match a curvature of a retinal surface and is further coated with a first coating to reduce damage to ocular tissues during use. The second blade includes a second longitudinal body portion and a second end portion extending laterally from the second body portion. A distal surface of the second end portion includes a cutting edge for cutting tissues, while a proximal surface thereof is coated with a second coating.
