Lasik (since 1994)
This combined technique is the most widespread procedure. First, a thin flap of cornea is created with a microkeratome. Then the flap is lifted up, allowing the laser to treat deeper instead of at the surface of the cornea. The flap is then put back into place and covers the treated zone. Both eyes are done during the same procedure, if needed.
For myopic patients, the laser flattens the centre of the cornea; for hyperopic patients, the laser modifies the periphery thus making the cornea more curved; and for people with astigmatism the laser gives back a spherical shape to the cornea.
2 days before the surgery, the patient will have to start eye-drops and then, continue those for 5 days.
Driving could start again after 24 hours.
Side effects :
A surgery is a surgery! Side effects may occur and complications are always a risk… but they are rare.
During the first 2 to 4 hours following the surgery, you may feel some discomfort which can be efficiently reduced with analgesics.
Your eyes may be more sensitive to intense light during the stabilization period (few weeks). You may see halos or stars around lights at night following a laser treatment.
Vision may fluctuate during the day until complete stabilization (few weeks).
Dryness could be felt during the first days and could be permanent. If it is too important, we may have to insert plugs.
Regression (tendency of the eye to bounce back toward its original shape) may happen during the stabilization period and is related to the individual healing of the eyes. An enhancement procedure may be considered after the 6 months if the surgeon thinks it is appropriate.
Cases of infection are rare : around 1/7,500.
