IVE HEARD THAT GLARE AND HALOS AT NIGHT CAN BE BAD AFTER LASER VISION CORRECTION?
Much of the negative information presented in the popular media regarding Laser Vision Correction has involved night vision problems, primarily glare and halos. When I started doing Laser Vision Correction in 1996, glare and halos were often present at night, causing difficulty for patients driving at night. However, with the new smooth Excimer laser profiles, the automated tracking systems and the large FDA-approved optical zones available on the VISX Star S4 Auto tracker and Autonomous LADAR Excimer Lasers, night vision complaints have significantly decreased. When we initially started Laser Vision Correction in 1996, we were using Excimer Lasers with 5.5 mm optical zones. The Visx Star S4 now has a treatment zone of 8.2 mm. With this large of an optical zone, glare has significantly decreased as a complication. I’ve also learned to very carefully measure the patients pupils in dim light (when the pupils are maximally large and dilated) and to then make sure that I use an optical zon
