Microkeratome

Microkeratome is a precision surgical instrument used in refractive surgery to create a corneal flap. It was first introduced in the 1990s and has since been an integral part of procedures like LASIK.

History

The microkeratome was first developed by Jose Barraquer in the 1950s. It was initially used in a procedure called keratomileusis, which was the precursor to modern LASIK surgery. The instrument has undergone several modifications over the years to improve its safety and efficacy.

Function

The microkeratome is used to create a thin flap in the cornea. This is done by moving the instrument across the eye while it cuts a layer of the cornea. The flap is then lifted to allow the surgeon to reshape the underlying cornea using a laser.

Types

There are several types of microkeratomes available, each with its own set of advantages and disadvantages. Some of the most common types include the Hansatome, Moria, and Amadeus microkeratomes.

Complications

While the use of a microkeratome has significantly improved the safety and efficacy of refractive surgery, it is not without risks. Complications can include epithelial defects, flap striae, and buttonholes. However, these complications are rare and can often be managed effectively.
