Learn More About LASIK
LASIK (laser in-situ keratomileusis) is a popular vision correction procedure to treat visual disorders stemming from an imperfectly shaped cornea. During LASIK, one of our International EyeCare surgeons gently reshapes the cornea so it can refocus light rays more precisely on the retina for clearer vision.
LASIK is performed using topical (eye drop) anesthesia in a two-step procedure:
- First, a thin, circular flap is made in the cornea using a microkeratome or femtosecond laser. The surgeon then folds the flap out of the way.
- In the second step, the corneal tissue underneath the flap is reshaped using an excimer laser (a cool ultraviolet light beam) to remove microscopic pieces of tissue from the surface of the cornea reshaping it. The flap is then put back in place to heal.
The procedure is quick and virtually painless. Today, LASIK employs advanced technologies including:
- 3D digital mapping of the eye
- Wavefront-guided or optimized excimer lasers
- Microkeratome or femtosecond laser flap technology
These advanced technologies provide superior safety and precision, enabling surgeons to customize procedures for the patient and better visual outcomes.
