There is no surgical procedure that is without risk, and LASIK is a surgical procedure. It is also a choice. If you do not feel the potential risks outweigh the demonstrated benefits, do not undergo the procedure.

Loss of vision: There can be loss of lines of vision on the vision chart that cannot be corrected with glasses, contact lenses, or further surgery. In extreme cases, there may be complete loss of vision.

Debilitating visual symptoms: Some people develop glare, halo effect and/or double vision that can seriously affect night vision. Even with improvement in visual acuity, there may be reduction in ability to see in low-contrast settings, such as night or fog. These symptoms may or may not improve with time.

Under or over correction: Very few people experience 20/20 correction the first time. You may require additional treatments (called corrections) or additional treatments may not be an option and you will still require the use of corrective lenses.

Dry eye symptoms: Your eyes may not be able to produce enough tears to keep the eye moist. This may result in loss of visual acuity due to blurring. This may or may not be alleviated with the use of plugs and drop therapy may be required on a lifetime basis.

Even with screening and performance of the procedure by a skilled surgeon, serious complications may occur.

Under the care of an experienced doctor, carefully screened candidates with reasonable expectations and a clear understanding of the risks and alternatives are likely to be happy with the results.
