What is LASIK?
LASIK is Laser In-situ Keratomileusis and refers to the use of laser technology to reshape the cornea. This surgical procedure combines the use of the microkeratome, or intralase, which creates a partial flap in the cornea, and the precision of the excimer laser which removes a thin layer of tissue from the cornea.
LASIK is performed in our Manassas office as an outpatient procedure. The actual surgery usually lasts less than 15 minutes, with most patients experiencing an improvement in their vision within the first few days of the procedure, some within hours of their treatment.
The eye is numbed with anesthetic eye drops. Then a partial flap is created in the cornea. The hinged flap is then folded back, exposing the middle part of the cornea.
The computer-controlled excimer laser, having been pre-programmed for the patient’s correction, is applied to the exposed corneal surface to remove a micro-thin layer of tissue.
In the final step, the flap is folded back into its original position. The treated area is completely covered by the flap.
Following the procedure, you will be given eye drops, protective sunglasses and eye shields to help your eyes heal. By the next morning, your vision will be greatly improved. Your vision may be slightly blurry for a few days, but most patients return to work within 48 hours.
About the Eye
Nearsightedness, or myopia, is a condition in which distant objects are blurry or even indistinguishable. This condition occurs if the eye is too long which causes the light rays entering the eye to focus in front of the retina.
Farsightedness, or hyperopia, is a condition in which distant objects are clear and close up objects are blurry. This condition occurs when the eye is too short for the cornea’s curvature, and the light rays entering the eye focus on a point beyond the retina.
Astigmatism is a condition in which the cornea has an oval shape, rather than being perfectly round. This can cause both distant and near objects to be blurred and distorted.
