In the LASIK system, the reshaping takes the area beneath each micro-skinny flap usually the usage of some other laser, the femtosecond laser.

During a laser eye remedy, anesthetic eye drops are implemented to lessen any ache, and the healthcare professional inserts a small ‘clip’ to maintain the eyelid open.
