I had my vision corrected with them in Birmingham approx 3 years ago, had LASIK, cost around £4K. It was a small miracle as far as I was concerned!
I was quite short sighted, so the first thing I did each morning was to reach for my specs. The freedom of being able to see clearly in the shower, or in the rain, or to go swimming and not have to worry about prescription goggles is fabulous. Simply not to have the weight/feeling of glasses on my face was such a novelty - spent the first few months still trying to push them up my nose even though they weren't there!
When I took my specs off on the treatment table everything was blurred, but when I sat up a few minutes later I could clearly read the sign over the doorway across the room - amazing.
I was really scared, so an extra member of staff came into the room to hold my hand and make soothing noises. The procedure was strange and a bit unpleasant, but not painful. I'm a real wimp but I'd have it done again in a heartbeat and second time around I'd be a bit apprehensive perhaps, but not frightened.
I'd say they do downplay the level of discomfort immediately post-op - after the anaesthetic drops wore off my eyes were very sore and streaming and I had to keep them closed, so you'll need someone with you to take you home. BUT, my recovery time was very quick. I got home, drank a fair amount of Bailey's, napped on the sofa for a couple of hours and when I woke up my eyes felt much less sore. The next morning they just felt a bit gritty and the next day they were back to normal. I think they say the first 6 or 7 hours are the worst and it's best to sleep through them.
I didn't have any eye drops or anything, just had to wear goggles during the night and sunglasses outside for a week or so - which was probably the worst bit because I felt daft wearing sunglasses in October.
A couple of years later I went to see my optician because the air con at work was making my eyes dry, and he said that if I hadn't told him I'd had surgery then he would never have noticed the scars because they were tiny and really hard to see - so the surgeon did a great job. Optician also told me to take cod liver oil to prevent dry eyes, I was a bit sceptical but it seems to work.
Re: the hard sell - they're a commercial business in a competitive market, like any other offering a service they chase leads. If you don't like the calls tell them to stop contacting you and to remove your details from their database. Shop round and see what other providers there are locally, but don't let it put you off having the procedure, if it's what you want.
You can't haggle over the price. I think any operation at a private hospital or clinic is expensive and this is very delicate surgery. Just because it's offered on the High Street doesn't make it less intricate or the surgeon less qualified or skilled. It's not like at the hairdressers where you can get it done cheaper if the junior practices on you!
You sound quite nervous and undecided, which is understandable. I was a terrified (but determined) bag of nerves with a very low pain threshold, so if I can do it I'm sure you can!
