Here is a very long comment about cataracts, surgery, and my experience.
I went through cataract surgery a year and a half ago. Before the surgery I was extremely near sighted (could see close objects clearly, distant objects were blurry.) Both eyes also had a strong astigmatism (cornea and/or lenses distorted giving double vision and wavy objects near and far.) I had worn hard contacts for years. As I got older I had to wear bifocals to read. Then I did try the one contact for reading and the other for distance. (Before considering this for cataracts most doctors prescribe one close and one distant contact lens to see if you can adapt.) My brain could not adapt; I could be driving and suddenly everything would be blurry as my brain would switch to the close vision eye instead of the distant one. I had to concentrate to bring focus back to the distant eye; really frightening on Los Angeles freeways.
I did a lot of research (as OregonLuvr and CougarFan can attest I am pretty OCD about researching things) and chose to have the more expensive implanted lenses to change from nearsightedness to distance vision and to correct the astigmatisms. I did not chose the “multifocal” lenses because, according to my research, they do not give as sharp a vision as the single distance lenses and usually there is more difficulty seeing at night with rings and blurry spot around lights. Also the brain must learn and adapt to focusing on one section or the other. Given my history with the contacts, my brain does not like to adapt. Many times people still need to wear glasses because fitting implanted lenses, of any type, is not an exact science. My surgeon said most who choose multifocals are very adamant about not wanting to wear glasses for anything and are willing to put up with any drawbacks.
I also chose to have the more expensive laser assisted surgery because the cuts are more precise and are said to heal faster with less complications.
Medicare only pays for the less expensive single focus basic lenses; single focus for distance or close vision in both eyes, or for one close and one distance. They will only pay for the usual “blade” surgery, not laser.
My surgeon said it is usual to wait three weeks after operating on the first eye to do the second. In my case he only waited two weeks because he did not schedule any operations the week before Thanksgiving, so there is some flexibility. The only minor problem that caused was taking two different sets of eye drops on two different schedules. I told him I was extremely anxious about EYE surgery and needles and would like to be “out” during the surgery. He said there would be a couple of time when they needed me to respond, but they could use Versed for conscious sedation. They did not want my blood pressure sky-high either.
During the surgery for the first eye, the only thing I felt was some pressure on the eye once during the laser part, and then moving to the other operating theater for the lens implant part. Two hours after I got home I could see distant objects clearly with that eye. I did have one complication, dry eye. When the surgeon telephoned in the evening I told him the eye was watering a lot and it felt like sandpaper rubbing over the eye when I blinked. He said to use some gel- type artificial tears and it should go away immediately and it did. I recommend to all my friends that they should have some at home just in case. After the next day follow-up appointment my vision was 20-20 and I was cleared to drive. (I did have to wear a contact in the un-operated eye so that my eyes could work together until the next eye was done.) If you are farsighted and have lenses for distance or nearsighted and get close lenses you will skip this step.
During the second surgery I felt nothing and remembered nothing. When I got home my vision was crystal clear. There was no pain, not even any discomfort. Next day appoint showed vision in this eye was better than 20-20.
As far as restricting activities, I was told to not go jogging or any high impact activities for about two weeks after each surgery.
I love not having to wear glasses, except for reading or close work. I can walk in the rain without having to wipe my glasses, (I live in Washington state) I can walk up and down stairs without having to hold my head steady (like with bifocals.) My vision is still better than 20-20.
