LASIK (Laser In Situ Keraromileusis ) is the most modern procedure, using the Eximer Laser, to correct nearsightness and astigmatism. ... The way the procedure is done is by applying some anesthetic drops to the eyes. Then the surgeon will use a keratone, an instrument similar in design to a carpenter’s plate, to raise the most superficial layer of the cornea. This is called a flap. The cold laser beam then gently reshapes the cornea & the flap is closed. In most cases both eyes can be done at the same time. Although no procedure is perfect, Eximer Laser technology allows us an unparalleled degree of precision and predictability. This makes laser vision correction in our opinion, the best procedure available for suitable candidates.
