Question: What can LASIK surgery cure other than near and farsightedness. I see haloes as well as bad vision and my eye doctor said that LASIK surgery can correct the haloes I see. Is that true?
Answer: LASIK Surgery is a type of Laser Vision Correction that can treat common refractive eye problems such as nearsightedness, farsightedness and astigmatism. In some cases it can be used to treat the minor near vision focusing problems from presbyopia, the normal loss of focusing due to age. Halos can occur for many reasons. Some people with high prescriptions and thick eyeglasses can see reflections and halos and reflections off the edges of their eyeglasses. If this is the case then a trial with contact lenses would allow the demonstration of the "edge free" optical effect before having LASIK. Typically using specialized coatings and materials in eyeglass lenses can also eliminate reflections and halos from thick eyeglass lenses. Halos can sometimes be caused by changes in the crystalline lens of the eye due to clouding of the lens-this may be the beginning of a cataract or could even been just a stable clouding of the lens that you have had from birth. LASIK probably would not be appropriate for this optical aberration. Halos can be caused by uncorrected astigmatism or other irregularities in the cornea. Irregularities in the cornea often cause high order aberrations to be present. A high order aberration called spherical aberration can cause glare and halos to occur that are not typically correctable with spectacles or soft contact lenses. If you have high order aberrations such as spherical aberration, Custom Wavefront Guided LASIK or Custom Wavefront Optimized LASIK can often correct or reduce the spherical aberration. These are only some examples of what might cause your halos-there are may more that might be related to other eye problems, conditions and diseases. You need to first understand the source of your halos and your eye doctor should then be able to explain why LASIK will treat the source of the halos. If your eye doctor is not a top LASIK Surgeon you should locate the best LASIK Surgeon in your area and schedule a consultation in order to have a second opinion. A top LASIK Surgeon will be able to measure all of the optical aberrations in your eyes as well examine the health of your eyes to make sure they are free of disease and qualify you as a good LASIK candidate who will benefit from LASIK Surgery.
