The operation itself is very simple now - at one time it was quite a procedure, and done under a general. The modern technique is done under a local (this is simple eyedrops, which are applied by a nurse when you arrive, there are three or four lots, including ones that make your pupils dilate as this makes the surgeons work easier)
The make a tiny incision, then use a special ultrasonice probe that liquifies the eye's natural lens, which is then sucked out. The artificial lens is then inserted, it unfolds and anchors itself once inside the eye.
There are no stitches, as the eye seals off the wound naturally, very quickly.
It is probably a good idea to stay indoors espescially if it is sunny, as the eye remains dilated for some time and brigh tlight can be uncomfortable for the rest of the day.
The eyeshield stays for that day, and every night for a few days/a week. If you think rubbing will be an issue, it can be left on but you will have to remove it for each lot of drops. Four times daily for a week (or maybe two, I forget).
The drops can make the eye sticky, you can use a cotton bud stick dipped in BOILED (sterile) water to clean off any "goo".
You just keep a watch for signs of infection, usually the discomfort (if any) fades after a day or two.
You can bend or carr heavy things for a while, as they both increase the pressure inside the eye, potentially this could cause the incision to open up and even allow the content sof the eye to escape or cause the lens implant to come loose.
During the operation the attending nurses can hold hands/head if it is really necessary.
