low-light vision problems

Until recently, laser vision correction (as well as eyeglasses and contact lenses), could only correct common vision problems like nearsightedness, farsightedness, and astigmatism. These types of vision problems are called lower order aberrations.

There can be other imperfections in your eye's optical system that may affect your vision clarity and how well you see in low light or at night. Called higher order aberrations, these imperfections are believed by ophthalmic experts to contribute to common low-light vision problems, including glare and halos.

Traditional LASIK procedures can't correct higher order aberrations, and neither eyeglasses nor contact lenses can help with these vision problems. An exciting procedure from Alcon, called CustomCornea®, is capable of treating both lower and higher order aberrations.

Diagnosing Higher Order Aberrations

CustomCornea® is a Customized LASIK procedure, using technology that can diagnose, measure, and treat higher order aberrations. How is this accomplished?

Your surgeon uses the LADARWave® wavefront device, made by Alcon, to send a beam of light into the eye. As the light passes through your optical system, the device measures your visual distortions and creates a three-dimensional map. This unique pattern is your wavefront map.

Your map, which shows any lower and higher order aberrations that you may have, is transferred to the laser. The laser uses the map as an exact guide to reshape your cornea and correct your vision.

Whether or not you have problems in low-light situations, make sure to choose a surgeon who can accurately measure and diagnose your vision disorders, and who will discuss your laser vision correction options with you thoroughly.
