What kind of problems does LASIK surgery correct?

LASIK is performed to correct the refractive errors of nearsightedness, farsightedness and astigmatism. LASIK corrects the corneal shape that causes these refractive errors so light can focus directly on the retina.

When was the first LASIK surgery performed?

1988
The First Laser Vision Correction Procedure (1988) The first laser vision correction procedure took place in 1988, when a 60-year old woman with a serious vision problem allowed surgeon Marguerite McDonald to perform the first photorefractive keratectomy (PRK) procedure on her damaged eye.

How has laser eye surgery benefited society?

Improved vision. In fact, about 95 percent of individuals who undergo laser eye surgery worldwide are satisfied with their visual results from LASIK. Also, a strong majority of LASIK patients achieve 20/20 vision or better following conventional laser eye surgery.

What are the disadvantages of laser surgery?

Risks

  • Dry eyes. LASIK surgery causes a temporary decrease in tear production.
  • Glare, halos and double vision. You may have difficulty seeing at night after surgery, which usually lasts a few days to a few weeks.
  • Undercorrections.
  • Overcorrections.
  • Astigmatism.
  • Flap problems.
  • Regression.
  • Vision loss or changes.

What’s the worst vision for LASIK?

To qualify for the newest LASIK technology (topography-guided LASIK), your refractive prescription should fall within the following: Up to -8.0 diopters of nearsightedness, or. Up to -3.0 diopters of astigmatism, or.

Does LASIK last forever?

But, LASIK is permanent. LASIK permanently corrects the vision prescription that you have at the time of surgery. This means that it cannot wear off. However, any underlying conditions such as presbyopia that progress over time can cause changes to your vision, making the original LASIK procedure less effective.
