What type of blade is used by the surgeon to make a clear corneal incision?

The appropriate type of blade used to create a clear corneal incision is a microkeratome. This instrument is specifically designed for making precise, thin incisions in the corneal tissue during surgical procedures such as LASIK or cataract surgery. The microkeratome allows for a controlled depth and angle of incision, which is crucial for optimal surgical outcomes. It produces a clean cut that minimizes trauma to the surrounding tissues, aiding in faster healing and reducing postoperative complications.

While a scalpel is a common surgical tool, it is generally used for other types of incisions and is not typically employed for corneal procedures where precision and minimal tissue disruption are paramount. Scissors are designed for cutting soft tissues and are not suitable for making incisions in the cornea. Lasers, though they are used in various surgical contexts, serve different purposes, such as reshaping the corneal surface rather than making a physical incision in the same way a microkeratome does.
