The first 4 hours after the op was uncomfortable, stinging pain in both eyes with watering and a streaming nose. Cloudy, blurred vision. Then, exactly four hours after, it suddenly stopped completely. Starbursts, glare around bright lights did hurt initially. Now, four weeks later, still there but less severe and no pain unless you stare too long towards a light. Position yourself so you do not look up at a person during a conversation and wear sunglasses as much as possible. I wore a baseball cap to work to stop overhead lights bothering me and closed the office curtains so |I did not look at bright light. Driving was and still is an issue. I avoid night driving but I have seen an improvement. Long vision is amazing. I would recommend this treatment. It's well worth a few hours of stinging and a few weeks of glare!
