Laser In Situ Keratomileusis (LASIK) is one type of laser vision correction or refractive surgery offered by UW Health in Madison.
What is LASIK?
Eye surgeons at UW Health Eye Clinics currently perform several types of LASIK surgery:
  • Laser In Situ Keratomileusis (LASIK) involves the use of a special instrument to raise a flap of corneal tissue. The excimer laser is then used to remove a thin layer of cornea underneath to treat nearsightedness, farsightedness and astigmatism.
  • IntraLASIK is the first blade-free laser technology using a laser to make a safer, more precise corneal flap during LASIK surgery.
  • Custom LASIK uses a wavefront analyzer to guide the treatment of additional imperfections in the optical system of the eye called higher order optical aberrations. This customized treatment can reduce the risk of glare, halos around lights or ghost images, and deliver better results than current conventional treatment.  
How do PRK and LASIK differ?

PRK offers patients an excellent option to achieve their desired vision correction but recovery of vision is delayed until the surface layer of the cornea heals. Your doctor may recommend separating the treatment of each eye by one week.
LASIK involves less initial discomfort and allows patients to see better sooner after surgery. Both PRK and LASIK produce about the same final visual result.
