I had a detached retina that required a vitrectomy, retina reattachment with stitches and laser and lens replacement.
Surgery was keyhole micro surgery and I was awake throughout under light sedation so I could carry on a conversation but felt blissfully calm and carefree.
I was walking out of the hospital 30 minutes after the surgery was completed.
Recovery was weird but not painful. I had a gas bubble placed in my eye to hold the retina repair in place and replace the vitreous fluid removed during the vitrectomy. As a result I had to do 'posturing' which meant staying in a facedown position with my nose parallel to the floor at all times for 3 days. At most I was allowed to be upright for 10 mins an hour which was basically to allow for eating and drinking.
This meant walking bent at the waist at a 90 degree angle and that I bought a cheap sunlounger with a face hole which I slept on in the living room and used during the day, I had my iPad positioned underneath so I could watch tv and do games. It was weird.
My eye was very red (pictures included to help you prepare a little as I had not been warned about how unpleasant it would look for a couple of weeks) and I had to wear a plastic shield for the first 24 hours then after that just had to be careful to not get water in it or lay on that side and put pressure on it. I had lots of drops that I had to use for a couple of weeks and the only real discomfort was because I had 3 stitches on the surface of my eyeball which were scratchy when I blinked for about a week.
Vision in that eye was non-existent for the first few days because of the gas bubble, then that slowly started to break down and be replaced by new vitreous fluid and it was like when you're in the pool wearing goggles and you have your eyes half underwater and can see over the waterline. Everyday the water line gradually lowered until it disappeared entirely.
My vision is permanently reduced in that eye but not because of the surgery the surgery did improve my visual acuity a little and prevented complete blindness in that eye, it just couldn't fix the long term damage caused by the underlying fucked-up-ed-ness of that eye.
Overall it was an easy surgery and recovery with some odd moments.
