I can share my exp. I have had lasik done 5 yrs ago and that is the best investment I have made.
My myopia was 800 degrees both eyes with 150 astig... almost like blind cat before. Went to this doc call Dr Jerry Tan. He was the first to do Lasik in Asia. Price a bit on the high side but I think eyes are impt. But I chose him because at that time, the machine he was using was a generation above those used at hospitals or other clinics. Faster, more accurate. Yes, I actually called up the clinics and hospitals and asked what machine they used and then researched on the net to compare the machines.
Anyway, there will be a pre-op tests of few hours. Then on actual day, before d op, they put in some numbing drops to your eye. Then during the op, the doc will open your eye lid with a device to keep it open so that u cant blink. It is not uncomfy cos ur eyes are numb. Then he will put something over your eye to create a flap. no feeling for me cos numb. Then he opens the flap using a device, then ask u to stare at a light. Then seconds later, he said he will close back your flap. then it is done. Very fast one.
Healing process : vision will improve day by day and then it stablises at about 1 to 3 months time.
Now my vision is left eye, better than 6/6 quite pin sharp. The tester says almost eagle vision. Right eye, 20 degree astig.
