I had mine done on 30 March this year.
My eye were -4 in one eye, -3.75 in the other.
I had them done by Mr Edwards at Sheffield Vision Centre, which is based at the Hallamshire Hospital in Sheffield: www.sheffieldvisioncentre.co.uk
I had ReLEx SMILE, which is one of the newest methods: www.sheffieldvisioncentre.co.uk/laser-eye-surgery/relex-flexsmile-eye-surgery
It cost just under £2000 per eye - I had both done. You can pay up front or there is a payment plan. There is no discount available - was fun listening to a man trying to negotiate one though - and any profits go into the NHS system at the hospital. This is an all-in price, including all checks before and afterwards, the procedure, the after care including the various drops, safety 'google' things for first week sleeping, and sunglasses.
I didn't want to risk going anywhere cheaper tbh - I had good recommendations, both in "real life" and there were good reviews online too. If I was having my eyes sorted I wanted to pay for it - guess I was happy to go with 'you get what you pay for' type of thought.
I have been really happy so far - it is now 2 months on. I could see without any issues the following day, I could drive the following afternoon infact, after my first post-op appointment. My eye sight at that point was already very good. At my last appointment, a month later, my eye sight was described as 20/20 and healing was excellent. I return at the end of this month for my 3 month check and envisage no issues.
They say the final 'how well has it worked' check is at 9 months. But so far everything has been fantastic and I am so glad I did it. I'm 43y and wish I'd had it done years ago! I love not dealing with lenses anymore.
They cannot prevent eye sight deterioration from nature ageing. You may still require reading glasses when you are older - that just can't be prevented. However, at least if that does happen in the future, at least I can just have standard reading glasses to pop on when needed, and not have to mess with two pairs or varifocals.
