Difference In Visual Acuity
Though there was no difference in visual acuity (the ability to see objects at a distance that is measured with 20/20 as its standard), there was a difference in night vision that was dependent upon which laser was used. In this study only the Alcon and VISX machine were used with Wavefront technology.
About 20-25% of patients had worse night-driving abilities following LASIK with the Wavefront machines, while about 40-50% of patients saw worse at night after being treated with the other two machines. It was also reported that VISX offered better identification at night than the other three lasers.
Though studies that compare the available lasers are just recently gaining popularity, it is likely that many more will take place in the near future, offering even better information for the discriminating consumer.
If you have read or heard anything about LASIK in the past year or two, then you probably know about the new Wavefront technology, touted as the newest advancement to help give you better vision than traditional LASIK can offer. What you may not have heard of is the newest add-on to Wavefront LASIK, called iris registration.
