In reply to arch:
I haven't have it done, although I'm totally specs/CL dependent and have been offered it for free. Optical Express (a bunch of crooks - avoid) offer it to optometrists when they're training or if you go for a job with them. Obviously I come across a lot of patients who have had the surgery and I find out exactly how well it's turned out in terms of how good their vision is, and any other symptoms they experience.
I would say in general it's pretty good, but also, quite a lot can go wrong. In just a small sample of everyone I've met or tested that have had it, I would say very roughly that somewhere around 50-75% have no complaints. One case I know well started out similar to me (-6.00ish) and one year after surgery she can get by without specs but needs them to drive - she's now about -1. Persistent dry eye symptoms are common (no surprise since the corneal nerves are severed, and these are what tell you to blink and produce tears). Slightly crap vision - e.g. haloes round light when night driving is not common but not very rare either. I've see a couple of cases of annoyingly crap (slightly hazy) vision - plus some interesting ones where the change in the refraction (i.e. going from needing to not needing specs) has knocked some of the eye muscles out of whack so the two eyes sometimes give up working together as they should (something called decompensating phoria - not a serious condition, but annoying).
Personally, I'm perfectly happy with glasses and contact lenses, and if they're not working right I can change them. With correction, my vision is excellent as I'm a young healthy guy, although it is absolutely mega-shite without correction (I'm -6.00-odd plus astigmatism). I don't want my best corrected vision to be worse than what I have now and I don't want to risk anything that's going to cause permanent or semi-permanent symptoms.
So, in general, it's pretty good but the risks are not insignificant and your daughter may well just end up wearing glasses again after a bit (but likely with a smaller prescription).
I would ask:
- what % of patients achieve (uncorrected) VA of 6/4? (6/6 will be their success criteria, but as a healthy 25 year old, she probably sees 6/5 - a bit better than 6/6, or 6/4 two bits better than 6/6). This will tell her how likely it is that her vision after surgery will be as good as what she has now with correction. If she's seeing 6/4 in specs now and then goes to 6/6 she might be pissed off even though the company count it as a glorious success!
- what % of patients complain of dry eye symptoms after 1 month, 6 months, 12 months?
- what % of patients report visual symptoms e.g. haloes, loss of contrast sensitivity after 1, 6, 12 months?
- what % of patient still use (distance) specs 1 year, 2 years on.
- what % of would-be patients do they refuse to operate on due to risks of poor outcomes (you'll need to compare this to competitors to make sense of it. A low refusal rate is bad news - it means they take risks to get business!)
They probably won't be able to answer these questions. If I didn't get satisfactory answers to these questions, they wouldn't get my money and they certainly wouldn't be cutting any flaps in my corneas!
Hope that helps. If it puts you off, sorry! I think it's a good treatment, but it involves slicing though your daughter's corneas and burning the tissue inside in order to reshape them. That obviously entails risks, and the company has very strong incentives to minimise your knowledge and perception of those risks. Your daughter should be absolutely 100% aware of those risks, and at a minimum should be able to compare different companies'/surgeons' hard data on what they achieve.
Take your time, gather a lot of information and comb through it seriously. We're talking about slicing into your daughter's corneas here, it's worth some serious consideration.
Good luck,
Jon
