SafeSight is the most advanced version of laser vision correction that is possible with modern medicine today. LASIK is 10x as risky, reduces the structural integrity of your eyes, can worsen glares, halos, and dry eyes, may not get you to your best vision possible. There are also issues of flap complications before and after surgery that may cause a LASIK patient to have poor vision or even go blind after treatment.
The major fear of LASIK after surgery is cutting the corneal flap. There have been many instances of corneal flaps dislodging after trauma to the head, getting poked in the eye etc. Thus, the flap created during LASIK carries two major risks: the risk of a poor flap placement or a disintegrating flap in the OR, and the postoperative risk of having a flap dislodging at any moment.
The end result of all these complications, if they are not properly treated is a corneal transplant and patient will end up being blind. This is why professional sports players, the US military, and airline pilots all opt for LASEK treatments over LASIK
Dr. Chynn use to perform LASIK and had LASIK on himself, but switched over to LASEK (or SafeSight) in 2004 because he realized that it was a much safer procedure with less risk and complications than a LASIK.
