In the LASIK procedure a thin flap is created in the
cornea. The flap is folded back to expose the corneal stroma or underlying
tissue. Some corneal tissue is removed by the laser, the flap is then
To create a flap, a corneal suction ring is applied to hold
the eye in place. This suction causes transient dimming of vision. The flap can
be created by a mechanical Microkeratome or a femtosecond laser microkeratome. A
hinge is left at one end and the flap is folded back to expose the stroma or
middle section of the cornea.
An excimer laser (193 nanometers) is then used to reshape
the cornea depending on the individual prescription of the eye. The laser
ablates or vapourises tissue without any heat, burning or cutting. However, the
smell of the ionising gases is memorable, like “burning hair”, though no heat is
created. The laser precisely removes minute amounts of tissue, tens of
thousandths of a millimetre.
The flap is then repositioned and remains in position by
natural adhesion, no stitches or bandages are required. Patients experience
little or no discomfort during surgery and some grittiness the night following
Visual recovery is rapid with most patients seeing very
well the next day and being able to return to work on the second day, depending
on their work environment. Patients who work in dusty, dirty places may need to
have a longer period away from work.
It is essential to use eyedrops for a period of time after
surgery. It is also recommended to refrain from strenuous exercise for 2 weeks
and from swimming for 4 weeks after surgery.
LASIK can be used to treat up to 8 dioptres of Myopia and
up to 6 dioptres of astigmatism.
determined mainly by the shape and thickness of the cornea. Thin and irregular
corneas are not suitable for LASIK.
The risks and complications of LASIK are very low. We
ensure this by thorough
assessment before surgery and diligent follow up afterwards.
