Ask an Eye Doctor and Get an Answer ASAP
Hello and thanks for your question. Are you available to chat?
Let me start addressing your questions:
2. There are other options, called premium intraocular lenses or presbyopia-correcting intraocular lenses. These lenses claim better independence from glasses after surgery for distance vision, near vision and intermediate vision... Now that being said...
Because the lenses are able to do this fancy thing, there is a loss of contrast sensitivity at all of these distances. Some people don't mind that, but some people will not put up with this loss of contrast sensitivity and they want the lenses out. In addition, there can be halos/glare associated with these lenses--most people have those symptoms resolve after 6 months to a year, but some people never have that resolve and again, they want the lenses taken out. Because of the compromised contrast sensitivity with these lenses, people with dry eye syndrome, glaucoma, macular degeneration and other eye diseases need to have a very frank discussion with their surgeon about getting these lenses implanted, because they are much more likely to not tolerate them.
3. Assuming you got the monofocal IOL and had that calculated for your clearest vision without glasses to be in the distance, then your computer screen maybe something you can see without glasses, if it is set back far enough (within reason of course), but anything closer than that you would probably need some glasses to see it (hopefully just over-the-counter magnifying / reading glasses.
4. Another alternative that the minority of people choose is the arrangement called monovision, if they know they have a cataract in both eyes that needs to come out. This is where one eye is "set" for distance vision and the other eye set for near vision. With this arrangement, the brain has to "learn" how to use one eye for distance vision and one eye for near vision. The people who do this already in contact lenses tend to be very happy, but it doesn't allow them to see the very small things up close and more importantly this arrangement obliterates their depth perception. So doing things like climbing stairs, parking a car, etc. become very difficult. For this reason, only a minority of people are able to tolerate this arrangement.
