LASIK is an advanced form of laser vision correction used to treat myopia. In many cases, it can also successfully treat people with hypermetropia and astigmatism.
LASIK is an acronym that stands for “laser-assisted in situ keratomileusis.” “In situ” translates into “in position” or “in place” and “keratomileusis” is the medical term for the reshaping of the cornea in your eye.
The procedure is performed to remove microscopic imperfections of the cornea (the thin dome at the front of the eye) that cause incorrect refraction of light through the eye. Corneal abnormalities can be uneven (astigmatism), be very flat (causing hypermetropia) or too curved (myopia).
While not everyone can benefit from LASIKsurgery, advances in technology mean it is now suitable for the vast majority – even for those who have been deemed unsuitable in the past.
The LASIK procedure differs from other forms of laser vision correction in many ways. One of them is that two different lasers are used. The first laser is used to create a small flap in the cornea.This provides access for the second laser, which is then used to make the tissue alterations that permanently correct your prescription.
Another huge benefit of LASIK is the short, usually painless, recovery period. Treatment is performed quickly (15-30 minutes), and many patients report rapid improvement in their vision—usually within 24 hours. Youwill be able to return to your normal activity almost straight away. Many people return to work the day after their treatment.
The best results of LASIK eye surgery are when used to treat mild to moderate levels of myopia, mild hyperopia and astigmatism.
The most advanced FEMTOSECOND LASIK operation begins with a three-dimensional scan of your eye. This provides your surgeon with a visual map of your unique eye anatomy so that he knows exactly how to correct your vision.
Once this is complete the procedure continues as follows:
After completing the treatment, you’ll find that your eyes are sensitive to light for the first 24 hours or so—for this reason, you’ll be told to bring dark sunglasses with you to wear after surgery.
The discomfort after LASIK is, if anything, very mild. If necessary, you can take pain relief medication. Your vision may be blurry in the first hours, but this usually returns within 24 hours.
