What is the difference between SMILE and LASIK?
Differences Between LASIK & SMILE LASIK treats all refractive errors. SMILE treats myopia with or without astigmatism, but not farsightedness or astigmatism by itself. LASIK requires a flap to be cut in the cornea, so the excimer laser reaches the inside of this part of your eye.
How does a microkeratome work?
The microkeratome works with two independent motors: one for the oscillation of the blade and the other for the forward movement. Once the cut is finished, the oscillation of the blades is stopped and the Pendular heads move to the start position. This allows very precise and smooth cuts.
Can I use phone after SMILE?

What is a microkeratome blade?
A microkeratome is a precision surgical instrument with an oscillating blade designed for creating the corneal flap in LASIK or ALK surgery. The normal human cornea varies from around 500 to 600 micrometres in thickness; and in the LASIK procedure, the microkeratome creates an 83 to 200 micrometre thick flap.
Who invented microkeratome?
In the 1950s, Columbian Opthamologist Jose Barraquer developed the microkeratome and keratomileusis technique. He would cut thin flaps in the cornea to alter its shape and investigate how much of the cornea was needed to be left unaltered to provide long-term results.
