Every time I turn around another friend has decided to have LASIK (laser in situ keratomileusis) surgery to help their vision. LASIK surgery could probably help my vision but the damn procedure just scares me! I would never have both eyes operated on at the same time. Further, it concerns me that we don’t know what may happen to those eye balls 10 or 20 years after surgery!
Now I can add a new concern – problems with night vision after LASIK surgery called the “halo phenomena” don’t seem to be effected. Even with successful LASIK surgery patients may keep experiencing disturbances in night vision, according to a report in the British Journal of Ophthalmology for August.
The results stem from a study of 110 eyes that were successfully treated with LASIK for myopia and astigmatism. A device called the Starlights system was used to measure changes in the halo phenomena, that is, the visualization of halos around light sources under night vision conditions.
