Lasik 101

Chances are, you’ve heard of LASIK. What about PRK, LASEK or Epi-LASEK? Right now, these terms may only be letters on a page to you — and that’s okay. Long story short, they’re all types of laser vision correction, a procedure in which an eye care doctor uses a laser beam to reshape the surface of the eye, making it more effective at focusing light and ultimately leading to better vision.


Today, LASIK is by far the most widely performed type of laser vision correction.1 Once the procedure is complete, patients may see details like never before almost instantly; noticing objects like a clock on the wall with clarity.

How long does LASIK take?

The entire procedure typically takes less than 30 minutes — and depending on the technology, as little as 10 minutes. Some patients have even been able to get back to their routine within a day.

How common is LASIK?

Over 16 million people worldwide have enhanced their eyesight and lifestyle with LASIK.2 As LASIK grows in popularity — more and more people are eliminating the causes of fuzzy vision and increasing their freedom from glasses and contacts — even if they’ve relied on correction their whole lives.

How well does LASIK work?

LASIK procedures have been performed for decades, and the technology has evolved over time to deliver better and better results. Though individual results may vary, the majority of patients enjoy 20/20 vision or better with their naked eyes after laser vision correction3 — and with CONTOURA® Vision, nearly 1 in 3 patients enjoy better vision than they had with glasses or contacts.4 Results like these let people enjoy many of their favorite activities without contacts or glasses!
