How does Lasik work?
The cornea, the transparent front window of the eye, contributes
two thirds of the total focusing power of the eye. Altering its
shape changes the focusing power of the eye. LASIK flattens the
cornea to correct short-sightedness or steepens the cornea for far
sightedness. This re-shaping process can also be used to correct
The surgeon creates a very thin corneal flap with an instrument
called a microkeratome. The laser is used to re-shape the bed of
the cornea under the flap. The flap is then re-placed which sticks
like cling film without the need for stitches. Vision recovers
rapidly with minimal discomfort.
