LASIK FAQ

Laser eye surgery is an umbrella term for several eye surgical treatments used to fix refractive errors (i.e., how your eye focuses light). The most common types of laser eye surgery include LASIK, PRK, LASEK and EpiLASIK.

However laser eye surgery can vary in the specifics of the procedure, the recovery time, which surgical instruments are used and your patient candidacy. You might be a much better candidate for PRK, for instance, than for LASIK.

Frequently Asked Questions About LASIK

What is laser vision correction?

It is a surgical procedure that uses a cool (non-thermal) beam of light to carefully improve the cornea – the surface area of the eye– to enhance vision. The laser eliminates microscopic bits of tissue to flatten the cornea (to remedy nearsightedness), steepen the cornea (to correct farsightedness) and/or smooth out corneal abnormalities (to fix astigmatism).

The objective of laser eye surgery is to alter the shape the cornea so it does a better job of focusing images onto the retina for sharper vision. LASIK and PRK are two types of laser vision correction.

Recovery Time and Complications after LASIK Eye Surgery (Blurred Vision, Feelings, etc)

Are LASIK and PRK safe?

The FDA acknowledges LASIK and PRK as tested, safe and reliable. Laser vision correction uses a cool (non-thermal) beam of light that is computer managed.

Although no one knows the precise number of complications, studies suggest that the incidence of small difficulties such as dry eyes and nighttime glare is around 3 percent to 5 percent, while the risk of major occurrences such as lost vision is believed to be less than 1 percent. There are no known cases of blindness from LASIK or PRK. Once again, outcomes typically are excellent.

Can I have both eyes done at the exact same time?

Many surgeons carry out a LASIK procedure on both eyes at the very same time. Because it takes longer for clear, comfy vision after PRK, many surgeons will wait a week or 2 between eyes for PRK.

Present FDA-approved laser vision correction techniques, such as LASIK (laser-assisted in situ keratomileusis), have a higher predictability of the outcome with a lower occurrence of complications.
