www.nucleusinc.com Cataract Eye Surgery. This 3D medical animation depicts the phacoemulsification and extracapsular removal of a cataract (cloudy lens), and the placement of an artificial lens. The lens of the eye is responsible for focusing images onto the back of the eye. It is normally transparent. As a normal part of aging, the lens begins to cloud and causes a gradual, painless loss in vision. Cataract removal is most often performed to better examine the back of the eye when monitoring for damage from certain diseases such as diabetes or glaucoma and to improve vision. There are two main types of cataract removal. The large majority of cataract surgeries are performed using the phacoemulsification technique. During the phacoemulsification technique an ultrasound probe breaks the cloudy lens into tiny fragments. The fragments are vacuumed out through a tiny incision. An intraocular lens implant is then inserted to replace the natural lens that was removed. Because the incision is tiny, stitches are often not necessary and visual improvement is usually noted relatively soon after surgery. During the extracapsular technique the cataract is removed as one entire piece. This requires a larger incision and stitches. An intraocular lens implant (artificial lens) is inserted to replace the natural lens that was removed. Recovery is usually slower, due to the larger incision. The stitches sometimes need to be removed, which is usually done in the office. After both …

I had cataracts in both eyes, there’s no way to prevent them, and the surgery to remove them was easier than you think…the day of the surgery sucks, but you walk out with pretty much perfect vision…it’s amazing!

they can give you a general sedative, you go to sleep before,then wake up after they are completely done, they do it on patients who ask, or some that are likely to flinch(like in your case) if they see the instrument coming…i am the same way, i had to be knocked out, it was fine

you really don’t notice it, if they don’t use stitches, you have no idea where the incision is…until you watched this video!

The surgery was done in ancient Rome but sticking a hollow needle into the eye and sucking out the lens or flipping over the lens

@Sherbert923 ~ Your eyes probably got so used to the HD it adjusted everything you saw to look like what the game did.. But isn’t HD a good thing? I’m not a doctor, so I suggest you go to the doctor.

I am 40 and just had cataract surgery on my right eye. I was sedated and slept for about five minutes and then woke up and conversed with the doctor as he finished the surgery. I did not feel anything other then wetness around my eye. There was no pain during recovery either. No tylenol needed. I am having a hard time adjusting because only one eye was done. The whole operation was about 30 minutes and as I said, Painless…the anticipation is worse then the procedure! Best of luck….

I have a question… is correct during this surgery used local anesthesic and sedation?… or just the first one?…
and after the surgery in how long time the patient must to wake up?…
thanks its a doubt…
26. January 2010 at 8:06 pm
Either one, my son had this done at 7 years old and they used a local, my father in law had it done and they sedated him.
28. January 2010 at 9:53 pm
I’ve had both eyes done with local anasthetic @ 38yo with 4 weeks between procedures, i have to say the most pain i felt was the sting of the eye drops you have first, the procedures themselves were painless, to anyone having this surgery don’t pannic, it just sounds and looks worse than it is

i have a question, why do you need to put in an artifial lense
like what about cateract surgerys in ancient times
they cut into eyes to remove cloudiness, did they insert things into the eye after the old lense was removed? I’m just curious…..
18. February 2010 at 2:36 am
@papasmurfXXX They don’t have to insert things, but who wouldn’t want them inserted? The artificial lens can correct vision to 20/20. Without it you are either near blind or you have to wear those real thick glasses that people used to wear. I had cataract surgery and for the first time since high school i have 20/20 vision and don’t need glasses.
18. February 2010 at 4:08 am
oh so in historical times they didnt insert anything, therefore your could go near blind or wear really thick glasses after having your caterract removed, eh, why not people who have glasses get new lenses to cure their vision.

22. February 2010 at 10:23 pm

22. February 2010 at 11:32 pm
@papasmurfXXX they could, but most get lasik surgery. Either way, it’s cosmentic and often not covered by insurance.
