Hi HA Kap
Yes I have recently had cateract surgery. Dec 2010 and Feb 2011. It has been one of the best things I have done!
It is outpatient surgery -- in and out the same day -- wearing street clothes. I went in at 10:00 am was out at 12:15 pm. Wearing no makeup I was wheeled into surgery room where Doctor and Assistant welcomed me. Doctor whiped my face with something then placed equipment around eye to hold in place. No problem. I was told to look at light. Doctor and equipment removed my lens (I honestly felt nothing) and all I could 'see' was blur. Then lense replaced. He gave me two stiches which I felt but absolutely no pain. I mean that. No pain.
After surgery I could see quite well, just a little blurry. Overnight I wore a see-through eye patch and everything was perfect the next day. Doctor gave me prescription eye drops before and after surgery and instructions not to bend down or wash my face or hair in the shower for one or two days.
Two months later I went through the process again.
Because I have 'long distance' sight and slightly different vision in each eye, the doctor took this opporunity to give me slightly different focal lengths in each eye.
I now wear glasses only for reading and with a much smaller adjustment level. Was as high as 3.25, after 1.75.
You should be able to trust your doctor and ophthalmologist/eye surgeon when she/he says your surgery will be fine.
Do not worry. Although you don't necessarily need anything to ease your worry, if your surgeon says OK, then go ahead. You will not feel very much at all during surgery, except for some new sensations, I repeat, it is not painful and the results are marvellous.
Cataract surgery has come a long way in just 10 years. No long time to recoup now.
