I had cataract surgery 2 months ago. Which enhancement is better Lasik or PRK?

My vision is worse than before the surgery. Which enhancement is better? Are these two the same thing - Lasek and PRK? How long should I wait after the cataract surgery to do this? I can't drive my car at night because all lights are distorted & I have no distance vision at all. When reading, I seem to have a droopy eyelid. Vision is dim until I hold my right eyelid up - then it's clear.I also just had a Posterior Capsulotomy today. How many days before I can expect to see without the film over my eyes?
