Microkeratome

A microkeratome is a precision surgical instrument containing an oscillating metal blade. It is used in the creation of the corneal flap necessary to complete LASIK surgery.

Your ophthalmologist will place the microkeratome over your eye, using suction to ensure that the instrument does not move during the flap creation. The blade on the microkeratome creates a hinged flap that allows the excimer laser to reshape your cornea in order to correct your refractive error.

Recent advances in LASIK technology have made modern microkeratomes vastly more effective than those used in the early years of LASIK surgery. These advances have led to more accurate results and vastly fewer complications.

The best microkeratomes on the market create corneal flaps that are uniform in thickness. This is accomplished largely by maintaining proper suction throughout the entire procedure. Two of the most effective microkeratomes available today are:

Moria M2
Hansatome™

Microkeratome vs. IntraLase®

Today, you also have the option of “bladeless” LASIK using IntraLase. There are advantages and disadvantages to both. At your initial consultation, your LASIK surgeon will advise you as to which method will work best for your particular refractive error and corneal characteristics. It is important to use a laser eye surgeon who is skilled at performing both microkeratome and IntraLase LASIK procedures.

The microkeratome method is generally faster, lasting about three seconds compared with the 15-20 seconds needed for IntraLase. There is also less suction needed with a microkeratome. As a result, patients generally experience less inflammation and discomfort.

While rare, there is a small risk of complications with the microkeratome, including:

The creation of a partial flap
A hole on the flap
The creation of a flap that is thinner in the middle and thicker on the outside edges

IntraLase flaps are created using computer technology, enabling your eye surgeon to better control aspects of the flap such as thickness and circumference. As a result, IntraLase flaps are generally a more consistent thickness throughout the edges and center.

Please contact an eye doctor in your area to find out which LASIK option is best for you.
