Which laser vision correction would have less chance of complication such as hazy vision after surgery: Lasik or PRK?

PRK has a lower chance of complications than traditional LASIK. 

 

However Intra-LASIK and PRK are both so safe that it is difficult to compare.  Both are among the safest procedures in existence.  Comparable to dental surgery in safety or laser hair removal.

 

Intra-LASIK and PRK are both similar to getting a laser treatment in your cornea, which is the fastest healing area of the body, faster than your skin.

Corneal haze has long been a complication of PRK.  With the newer lasers and medications used during and after surgery to modulate healing it is much less common than it has been.  The newer lasers create a smoother ablation and this substantially reduces the risk of complications.   Most surgeons now use a drug called Mitomycin that reduces the chance of haze substantially.  Patients can do their part as well.  Avoid pregnanacy for the first few months.  Substantial changes in hormonal status substantially increases the risk of haze.  The use of UV protecting sunglasses for a year after your procedure is also important, even on a cloudy day.  Lastly, many surgeons believe that the consumption of one gram of Vitamin C per day for the first year is also helpful.
