I had mine done in March 2016
My eye were -4 in one eye, -3.75 in the other.
I had them done at Sheffield Vision Centre, based in the hospital.
I had ReLEx SMILE, which at the time was one of the newest methods:
It cost just under £2000 per eye - I had both done. You could pay up front or therewasis 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 was 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.
There were cheaper alternatives with some high street branches, etc. but 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.
Its been over 3 years now and I have been really happy so far.
I could see without any issues the following day, I could drive the following afternoon, after my first post-op appointment. My eye sight at that point was already very good. At my appointment a month later my eye sight was described as 20/20 and healing was excellent.
On the day my appointment was at 8:30am and I was walking out of the surgery by 9:15am.
The procedure didn't hurt at all. It felt a little strange - but definitely no pain. It was so quick. Afterwards I was given a range of drops, some dark goggles (to wear that day and in bed for first few days) and sunglasses - I needed these the first day and whenever it was bright for a short while. About 2 hours later my eyes began to sting and water. Again, not painful but uncomfortable. However, this only lasted about an hour or so and gradually lessened. My eyes were watery for a while that day and my eye sight was blurry and hazy but gradually cleared as the day went on - I could use my laptop and phone later that day, zoomed in. Buy the evening I could see - close up was still hazy but not long distance.
The next morning I could see really well. I had a follow up that morning and my eye sight was pretty much 20:20 vision already, and much better than my contact lens correction had been. The follow up a week later was even better results and healing was quick and pain free. I did wear dark glasses for a little while if it was bright, but the sun sensitivity reduced with time. And initially I had some glare/halo effect when driving at night, I used to have this with glasses and lenses anyway but again it reduced - this has gone entirely now.
So far everything has been fantastic and I am so glad I did it. I had mine done at 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. They also took the ageing into account when doing them, so I assume they over correct perhaps to do so, though that may be age dependent.
