Ans. Yes, the cylindrical errors up to 6 are treatable. In our experience with the laser technology we use, the Wavelight 500 Hz system, we have near zero night vision problems from even US FDA data. In our practice we till date have seen no glares, haloes etc.
This also depends on one test which checks your pupil size dynamically in light and dark, which is part of your evaluation process with us. Your friend may have been treated with an older technology and hence facing these issues. In fact our laser is one of the best for re correcting such issues of older lasers with Topolink treatments.
