Night glare after LASIK is caused by your cornea being in 2 pieces forever, since the LASIK flap is cut, lifted up, put back down–and never fully heals. This is why you can enhance a LASIK years later by digging the flap back up–because it never heals. Because of this, after LASIK, light is invariably scattered and refracted by the flap interface. Put another way, the “sandwich” configuration of your cornea is what causes backscatter of light. This is most noticeable at night–and causes night glare.
Because your cornea is never cut and no flap is made in SafeSight™, night glare is avoided. In fact, after SafeSight™, many of our patients say that their night vision is actually better than it was before in glasses or contacts!
Dry eyes after LASIK is also caused by cutting the flap. When this cut is made, most of the corneal nerves are cut–and never grow back. Your eyes are lubricated by the tear film, which is distributed when you blink. You blink when you (subconsciously) sense your eye drying out. This is why you cannot keep your eyes open forever–eventually, this sensation of dryness is so powerful, you cannot avoid blinking.
But what happens when you cut most of your corneal nerves? Published studies have shown that normal people blink every 5-10 seconds–but after LASIK, they blink only every 10-15 seconds. In fact, they’re staring themselves dry without even knowing it!

Dr. Chynn has also eliminated all complications in the operating room by no longer cutting flaps. That’s why we can have the only glass “open OR” in NYC! Do you think we could have people watching on the sidewalk during their lunch, invite companions into the OR, and stream our live LASEK seminars live if there was even a small chance of a major complication? Of course not!
