I had a macular hole repair. I was told it was an urgent operation and you could lose some of your sight in that eye if not repaired asap. I was also told there was a possibility of the other eye developing a hole as the eyes tend to mirror one another. I had a holiday abroad booked when I saw the consultant but was allowed to go. He booked me in as soon as I came back. He really emphasised how important it was to have it done asap for best outcome. The operation took about an hour, if that, and was done under a local anaesthetic and was painless. It was quite fascinating to watch it on the screen. I experieneced no pain afterwards.
My consultant was adamant that I observe 'face down' for 5 days. Less hard to do than you imagine and well worth it. I followed his advice to the letter and had no problems since. I had a nephew in law who had the same operation, didn't follow instructions and ended up with 75% vision. Five days is nothing compared to the rest of your life with sight.
I rented structures to help me cope with 'face down' - four in all. The ones I found most helpful were the table to lie on and the chair. The sleep one was no good for me. I ended up using the seat pads of the sofa on each side of me at night plus pillows to prevent me rolling over onto my back. I constructed a 'face down' structure from, I think, heavy tomes covered with pillows to enable me to breath. Well worth trying in advance to get something that suits you. I think I would have used crates if I had had time to figure that out. The whole idea of face down is to keep pressure off the back of your eye. You can shower, as per medical advice, as long as you look down. You can also visit the loo, eat etc at a table as long as you look down. Sounds a right pain, it is , but worth it. My consultant was delighted with my result and my optician told me it was the best result he had seen in his entire career and he is no spring chicken. I haven't had any problems since.
Do not delay having it done. I didn't develop one in the other eye. As another poster has said it does accelerate cataracts and I was made aware of that. True to his word I developed them two years later. It was dealt with and no problem since.
Small tip - when wiping your eye, boil some water, put in a container, let it cool, and use only that water to wipe eye with a cotton pad for next two weeks. Change daily. Advice from Moorfileds hospital. You can see it on their website. Also works for cataract operation.
BTW you can use computer, watch TV, read using the bed or chair and a mirror for TV. What's not to like about five days rest, doing your own thing, and no-one can say a word.
Good luck, OP.
