I had both eyes done about 4 years ago, I under went the Lasik procedure.
I was short sighted in both eyes and both eyes where rugby ball shaped so I was on the borderline of not being able to have it done at all.
However went for it, had both eyes done at the same time and have better than 20-20 vision, I can read off the chart.
The downside? well I am now going v slightly long sighted - this happens to us all as we get older and I was warned that this would happen. Also in the beginning I was getting a corona effect around reflective objects at night such as road signs - this dimished after about 3 months and is hardly noticable now.
Was it a life changing experience - in my case yes.

As noted in previous posts there are no long term studies available about the long term effects, so yes we are all test subjects for now.
What ever your Dad decides - good luck to him.
Oh by the way the disclaimer list that you get before the surgery can induce rapid bowl movements as you learn what could go wrong!
I still went ahead - was I stupid, thats up to you guys to comment:omg

Edit: Sorry should have mentioned I had it done at Leeds, can't remember the company, but Richard Branson and Sharon Davis had it done by the same company - I thought I might sue Richard if it went wrong for endorsing a dodgy process!
