All LASIK patients will experience some degree of temporary night glare for about 6 weeks post-op. This is due to microscopic swelling in the flap which goes away. Many describe it as comparable to their vision at night with a soft contact lens. ASA patients can experience similar temporary glare as the surface of their eye heals. With Dr. Dell’s technique of measuring the pupil size in near total darkness using an automated infrared pupillometer, adjusting the excimer beam size to suit the pupil, and using sophisticated eye tracking technology, night vision complaints are very unusual. Many of our patients tell us that their night vision is superior after surgery to anything they had prior to surgery.
