What are the benefits of using wavefront technology?

Wavefront-guided LASIK not only corrects the eye’s nearsightedness, farsightedness or astigmatism — much as glasses, contacts or conventional refractive surgery do — it also reduces the possibility that higher-order aberrations may cause glare, poor night vision, halos and blurry images after surgery. Higher- order aberrations are distortions in your vision that cannot be corrected with glasses and contacts and can only be measured with wavefront analysis.

One of the main differences between conventional LASIK and wavefront-guided LASIK is that with conventional LASIK, the laser tends to use the same power treatment over the center and sides (periphery) of the cornea, whereas wavefront technology modifies treatment over the peripheral cornea to further improve optical quality. For people with larger pupils, particularly under low-light conditions, such as at dusk or nighttime, quality of vision is generally improved.

It is important to understand that wavefront-guided LASIK may not be suitable for everyone. Even with wavefront-guided LASIK, vision after surgery may not be perfect due to individual differences in healing after laser surgery. The ideal LASIK patient is more than 21 years old, since refractive error is more likely to still be changing in people younger than this. Some people more than 21 years old are still experiencing change in refractive error, making them unsuitable for LASIK.

Your ophthalmologist can determine if wavefront- guided LASIK is an option for you. If you are a candidate for this advanced procedure, you’ll join a growing number of people who are enjoying a better quality of corrected vision.
