Yah lor, after op very fast go home liao. I can't exactly rem but I don't think the whole thing took me 2 hrs. It's faster than that.
Actually I didn't really get a chance to see if the machines look scary, haha. Cos once you get into the room, the nurse will immediately help you to lie down on the bed, then the doc will move the machine over your eye already! The machine cuts the cornea. During the procedure, just look at the red dot of flash and follow whatever instructions your doc tells you, very straightforward one. You will feel something pressing into your eye area, but it's not painful.
After the surgery, don't watch TV, don't read, don't use the computer. For me, I just lie on my bed. I wanted to sleep but couldn't really do so cos my alarm clock will ring every 15 mins! Have to drip the lubricant eyedrop every 15 mins mah. Also the antibiotic eyedrop every few hours. You won't be able to fall asleep one lor.
