What is Mechanical Microkeratome Lasik? Different to laser Femtosecond Intra-Lasik
The first step of Lasik eye surgery is to create a thin flap in
the superficial layers
of the cornea. Traditional mechanical
Lasik surgery uses a metal blade called microkeratome to made
the flap, the laser Lasik surgery made flap with
Femtosecond
laser ( Femtosecond
Lasik).
In traditional mechanical microkeratome Lasik, the microkeratome
has many moving metal parts and the blade is inserted and must
oscillate freely. There were problems with quality control with
some of the blades. The flap that is reflected might have jagged
edges due to these blades leading to irregular surface of the
cornea. This can give rise to vision problems such as
astigmatism.
While IntraLase Femtosecond system has greatly reduced the
number of side effects and improved the safety of the procedure
in comparison to microkeratomes, the expenses of the procedure
with the IntraLase has gone up by almost $300 per eye.

cost of a Femtosecond laser and an annual maintenance fee are
the biggest factor.
