What is Lasik

Lasik is the abbreviation for laser-assisted in situ keratomileusis. It is a refractive surgery procedure that reshapes the cornea and attempt correct vision disorders such as myopia, hyperopia and astigmatism. This procedures uses highly specialized laser called excimer laser that alters the shape of the cornea which is the transparent front covering of the eye and eliminates the need to use contact lenses or eye glasses.

How does Lasik work?

During the Lasik procedure, a corneal flap is created first using a microkeratome (a precision surgical instrument with an oscillating blade) then the flap which resembles a soft contact lens is pulled back so that the underlying corneal tissue is exposed. Next, the laser beam is applied to the interior surface of the cornea to reshape the tissue. The excimer laser is computer-controlled to remove tiny amounts of tissue to precisely reshape the cornea. The excimer laser is a cool laser, it doesn't produce any heat, so no damaged is caused to the surrounding tissue.

After the laser treatment, the flap is gently repositioned onto the treated area without sutures. It acts as a natural bandage, it eases the discomfort of the patient and fastens the healing process.
